State Planning & Research (SPR) Implementation
The following list highlights implementation activities undertaken during Fiscal Year 2004:
| SPR# | Project
|
| 473 | Arizona Intelligent Vehicle Research: 2003-04 was the
first full winter of operations for the projects seven research snowplows. The
deployment of on-board warning systems was not complete until February 2003, so testing
was limited in that winter. This year, four snowplows equipped with collision warning
radar, and three others with passive-infrared night vision, completed more than 40,000
miles of highway operation in a variety of winter storm conditions. These tests, on seven
highway segments in northern Arizona, established the advantages and limitations of the
two low-cost commercial driver-warning systems. As a result, this project recommends wider
use of collision warning radar for snowplows and other ADOT fleet units. However, the TAC
recommends further winter storm evaluation of night vision, and has suggested further
design refinements by the manufacturer. |
| 486 | Highway Facilities for an Aging Arizona Population: The
immediate outcome of this research was Arizonas successful competition for a federal
grant to set up a demonstration project on US 60 near Sun City to study this issue in
detail. The grant amount is $91,950 ($73,560 in Federal and $18,390 State funding). In the
long run the improvements made to better accommodate older drivers are expected to reduce
the frequency of crashes. This will save money and lives. Each future fatality avoided
saves over a million dollars, each incapacitating injury crash avoided saves over $50,000,
each non-incapacitating injury crash avoided saves over $17,000, each possible injury
crash avoided saves nearly $10,000 and each property damage-only crash avoided saves over
$6,000. |
| 519 | PM10 Research for Developing Educational Tools and Outreach
Programs. The Final Research Project Report was published October 2003. This project developed an educational outreach and certification program for the Maricopa County PM10 non-attainment area. It is intended for educational use statewide. The logo Blue Skies Training Program was adopted for this training. On June 11th, 2004 the first training session was conducted and was very successful. It is managed by Beverly Chenausky, Air Quality Programs Supervisor, ADOT TPD. Another session will probably be scheduled in the fall. There are also plans to implement an online training package presently in the early stages of development. Program information is available at this web location, http://tpd.az.gov/air/blueskies/main.htm |
| 535(1) | CVISN Safety Information Exchange, Nogales Port of Entry. A
pilot test of hardware and software has been designed and will be implemented during the
next fiscal year. |
| 539 | Third Party Transaction Cost-Benefit Analysis: The
research showed that the cost per transaction for MVD Customer Service is $10.66 versus
$9.54 for Third Party (a savings of over $2.1 million per year). In addition to the cost
savings of the Third Party Program, the Program provides a number of significant
intangible benefits, such as: reduced wait times in existing Customer Service offices,
more convenient hours and days of service availability, reduced customer travel time and
improved customer goodwill, reduced need for new buildings, MVD staff, and equipment,
improved image of MVD responsiveness, process improvement, and demonstrated success of
e-government and private-public partnerships. |
| 543 | Strategies to Integrate Environmental Stewardship into
ADOTs Business. Draft Report was submitted to the Technical Advisory Committee
(TAC) in May, 2004. TAC review completed and Final report submitted for Technical editing.
Publication pending. The projects recommendation is to be presented to the ADOT Core Team at one of its regular meetings for consideration. At the same time a Stewardship Committee was constituted to look into ways that ADOT can implement needed efforts. This team is led by ADOT Health & Safety Administrator Sonya Herrera. |
| 560 | Improving Construction Communication. Eight actions
are being taken to improve communications on the 59th/Grand Project. (1) A
plans review has revealed project milestone dates and bulletins will be issued for each,
at minimum. (2) Regional signing has been reviewed and may be supplemented. ADOT and
Glendale are discussing additional local signing. (3) The existing design
site, grandavenuecorridor.com is being transferred to construction for project specific
use. (4) We have requested that Glendale hire a fulltime project liaison and this duty
will pass to that position if its created. (5) Radio advertising will be purchased
as part of the project kick off public information campaign. Additional use
will be as necessary, only. (6) Television will probably be relegated from a construction
standpoint to public relations activities, however, Glendale may use for local promotion
during construction. (7) ADOT will work closely with local newspapers and the AZ Republic
to publicize all elements of the project. No paid advertising is expected for
construction, but may be purchase by Glendale. (8) Numerous briefings are planned prior to
construction to keep facts straight. |
| 566 | Alternative Modes as an Air Quality Mitigation Strategy. Four actions are being taken. (1) Move AZ has incorporated alternate modes into its planning process. (2) ADOT will more actively participate on the CMAQ committees. (3) ADOT will request research through the Arizona Transportation Research Center on an as needed basis. (4) ADOT has implemented a statewide program. PTD is assisting ADOT trainers with the Telework program so telework can be an option statewide, not just in Pima and Maricopa County. |

The new U.S. Environmental Protection Agency standard for particulate matter focuses on the size range of particles that are easily respired and retained within human lungs, 0.1 to 2.5 microns in diameter (PM2.5). Our current knowledge of particle emissions from transportation-related sources is based primarily on the existing PM10 standard, a measure of the mass of particles smaller than 10 microns. PM10 is dominated by the larger particles, so that current understanding of the contributions of transportation-related sources to PM10 is not applicable to PM2.5. Future transportation models that predict ambient particle concentrations will have to incorporate the PM2.5 standard. Because large variations in emission factors occur because of variables like climate, roadway type, and vehicle type and conditions, generic emission factors from other regions or laboratory studies will not suffice. Accurate modeling of the Phoenix urban area requires direct measurement of particulates, their compositions, size distributions, and concentrations and accompanying meteorological conditions in three dimensions along and away from the linear sources that major roadways represent. Measurements of particulates must be accompanied by accurate counts of vehicle numbers, types, and their speeds.
A significant challenge in a field study of roadway emissions is separation of the urban regional plume from the freeway emissions. A second challenge in an area of complex terrain like Phoenix and Tucson is that the concentration of particles in the urban plume and the dispersion of roadway pollutants are both dependent upon position within topographically controlled wind fields. The experimental design must address these problems.
There is a serious disparity between receptor-model and emission-inventory estimates of the contribution that combustion sources make to fine particulates. For the Phoenix area, receptor models estimate that 70% of primary fine particulates come from combustion. In contrast, emission inventories estimate that 18% come from combustion. Part of the disparity is due to an underestimation of PM2.5 from vehicular exhaust coupled with possible overestimates of re-entrained dust. More of the disparity may stem from a lack of knowledge of the composition of re-entrained dust, which may consist of aggregates of soil particles with carbonaceous material rather than just soil particles alone. A field study combined with numerical modeling is the best way to answer this question. The accurate evaluation of any fine particulate control strategies cannot proceed without our knowledge of the different contributing particle fractions.
The proposed study will provide data about transportation-related particulates that are essential for future transportation modeling due to (1) the serious non-attainment status of the Phoenix airshed, (2) the continuing growth in traffic caused by growing population, and (3) the eventual enforcement of the PM2.5 standard. The work on emission factors for re-entrained mineral dust will be the first such study to use quantitative single-particle analysis methods. The aircraft study will provide data about the 3-dimension variation in aerosols and associated meteorological conditions, essential for accurate fine-scale modeling of linear roadway sources. It will provide optical data that are linked to data about the aerosols chemical and physical properties, essential for modeling of visibility impairment. The combination of rapid population growth in Maricopa County, current and planned future freeway construction, and the non-attainment status of the area with regard to federal standards make it imperative that we gain a better understanding of transportation-related particulates and of their dispersion and transport in our desert, complex terrain region. Delay in examining these issues will only make it more difficult to address these issues.
To determine the contribution of vehicle-related emissions on major roadways to PM2.5 and PM10 in the Phoenix airshed;
| · | For vehicle-related emissions to determine the relationships between particle properties such as individual-particle and bulk composition, size, and optical properties; |
| · | To determine emissions factors for re-entrainment of mineral dust particles from major roadways, arterials and freeways including data by vehicle type and speed; |
| · | To determine whether re-entrained mineral dust is aggregated with significant amounts of carbonaceous material; |
| · | To improve numerical modeling of fine particulate dispersion modeling |
| · | To make progress on the resolution of the disparity between receptor models and emissions inventories of fine particulates for the Phoenix airshed. |
| · | Evaluate existing literature and estimate particulate deposition rates |
At a minimum, the following tasks will be accomplished:
| 1. | Sample and analyze particulates using ground-based individual-particle and standard PM2.5 and PM10 mass samplers on freeway medians and arterials at either existing Arizona Department of Transportation (ADOT) traffic-counting locations or co-located with special counters. Quantitative single-particle analysis of inorganic particles by automated scanning electron microscope should cover the size range of 0.1 to 10 microns, from which the equivalent of both PM2.5 and PM10 can be extracted. |
| 2. | Measure the temperature, relative humidity, and wind speed (down to 0.5 m/s) at the freeway median sites for use in modeling. Measure the average fine particle concentrations. |
| 3. | Make measurements both upwind and downwind of such segments in order to separate the contribution of background emissions from roadway emissions. Both single-particle and mass aerosol samplers should be used. The aerosol optical properties and meteorological conditions should be measured. |
| 4. | Numerically model the deposition of vehicle-related fine particulates. |
| 5. | Determine the mass emission rates and relative contributions of combustion particles, other vehicle-related particles such as from tires, and re-entrained mineral dust to primary fine particulates emitted from major roadways in the airshed. |
The proposed research will be of direct relevance to the Environmental Planning Section of ADOT and falls within the areas of responsibility of Air Quality personnel. The work will also be coordinated with the Air Quality Division of the Arizona Department of Environmental Quality (ADEQ).
The project is completed except for final report revision - which is currently ongoing. All field experimentation and analysis is finished. The final report draft review is completed. Principal investigator has promised completed final report revisions September 2004.

Certain areas in the Maricopa County PM10 non-attainment area consistently exceed the PM10 National Ambient Air Quality Standards (both the 24-hour and annual standards). These high particulate pollution areas should be addressed by planning and developing an effective program to reduce particulate emissions and urban haze and should be based on tangible data addressing the efficacy of proposed abatement methods. One difficulty in constructing such a program is the scarcity of information for Maricopa County linking the sources of PM10 to high concentrations and specific costs and benefits for particulate control methods.
The Arizona Department of Transportation (ADOT), along with other agencies and industrial and area sources, are consistently asked to commit to air quality control measures without any background data to assess emission reduction levels or control measure costs or benefits. Many of the measures that are being committed to by the agencies and other sources are not having the needed impact to address the PM10 pollution problem, not only on a regional basis, but at locations experiencing high particulate concentrations. This results in the continuing threat of federal sanctions on highway construction funds.
A Brown Cloud Study was done in 1990 in Phoenix, but has not been updated. The study did identify transportation related PM10 sources as the major contributor to the problem
In its 1998 recommendations, the Governors Air Quality Strategies Task Force suggested that the Arizona Department of Environmental Quality (ADEQ) and ADOT participate in research to identify the larger emission sources and evaluate potential control measures for areas with high particulate emission concentrations. As a result, Senate Bill 1427 (1998) provided for a $50,000 appropriation from the state general fund in Fiscal Year 1998-1999 as a state match to ADEQ to monitor specific high PM10 pollution sites as the first step to reduce emissions in those areas. ADEQ is currently seeking the necessary matching funds for the $50,000 appropriation. This proposed project, along with the ADEQ project, is beneficial to ADOT as the projects will help both agencies meet the air quality commitments of the Governors Task Force. ADOT would be represented on the ADEQ project team as both a partner and a stakeholder, coordinating tasks through this proposed project. Because any potential sanctions for missing an air quality deadline will heavily impact ADOT, we are proposing that ADOT match the ADEQ project with this proposed project.
| · | Identification of sources of PM10 and their contributions. |
| · | Development of recommendations regarding effective and efficient measures which would address the cause and effect of high particulate levels in specific areas. |
At a minimum the following tasks will be accomplished:
| 1. | Physical samples at Greenwood location. Differentiate PM2.5 and PM10 |
| 2. | Chemical analysis, separating geological and combustion contributions. |
| 3. | Use video cameras in strategic locations for supplemental source apportionment. |
| 4. | Numerical Modeling |
| 5. | Traffic surveys for vehicle counts and classifications for fleet mix in area of study. |
| 6. | Build micro inventory around monitor, using in part the available with the Maricopa Association of Governments (MAG) and their contractors |
| 7. | Dispersion Model: Determine I-10 impact with respect to re-entrained vs. combustion contributions, including 27th Avenue and the freeway ramp. |
EXPECTED IMPLEMENTATION
While transportation construction projects would probably be impacted the hardest, most of ADOT would be affected in terms of the way highway projects are planned, programmed, designed, contracted out, and ultimately completed. As ADOT is an affected party in this effort, it is recommended that ADOT have at least two representatives on the ADEQ project committee. At the same time, two ADEQ representatives will be on the Technical Advisory Committee for this project, as suggested below.

Animal/vehicle collisions result in human fatalities, injuries, and extensive property losses every year in Arizona. As the Arizona Department of Transportation (ADOT) upgrades existing rural highways the problem intensifies. Collisions increase with speed and traffic volume. The issue of vehicle/wildlife collisions is becoming more of a concern to citizens and resource managers. These collisions cause millions of dollars of property damage and litigation associated with such collisions is increasing. These concerns are impacting highway construction costs and project schedules as highway designers and scientists look for solutions to the problem. A lack of scientifically collected data on the effectiveness of various mitigation measures compounds the problem especially here in Arizona where no valid studies have been conducted.
ADOT will be implementing a comprehensive package of measures to address wildlife concerns as part of the upgrade of SR260 from Payson to Show Low. These measures will conservatively cost more than 3.5 million dollars. None of these measures have been implemented in Arizona before nor has their effectiveness been evaluated. Since animal/vehicle collision mitigation methods will be used in the future on other highways in Arizona, it is imperative that these methods are evaluated to determine their effectiveness at increasing highway safety and maintaining wildlife permeability.
The objective of this proposed research is to measure the effectiveness of the various highway design features to reduce wildlife/vehicle collisions and maintain habitat connectivity on the state highway 260 corridor.
At a minimum, the following tasks will be accomplished by the researcher:
| 1. | Meet with the Technical Advisory Committee to discuss the scope of work
and action plan. |
| 2. | Document and report the incidence of wildlife/vehicle collisions along the
entire length of the study area. Analyze and compare the wildlife/vehicle collisions along
the test area with the data in the same areas collected since 1987. |
| 3. | Monitor the movement of adult elk in three time periods; pre-construction,
during construction, and post construction. Analyze the data to determine the degree to
which wildlife permeability across the highway is maintained. |
| 4. | Monitor the wildlife-proof fencing to determine its effectiveness at
limiting wildlife access to the fenced highway. |
| 5. | Document the research effort and findings in a final report. |
This research will provide the required data for the need, design, location, and frequency of underpasses for the conveyance of wildlife under a highway. It will evaluate the effectiveness of various wildlife-proof fence configurations in containing and directing large game animals. The research will evaluate the effectiveness of one-way gates and escape ramps in allowing large game animals to return to the off-highway side should a breach in the fence occur. This research will establish a database that will provide more complete information on the frequency, location, species, and damage related to wildlife/vehicle collisions
Phase I of the project is nearly completed with work in progress on an interim phase I report. Phase II of the project is currently on-going with good progress.

The Arizona Department of Transportation (ADOT) recognizes that it has an important role in environmental protection. It is in this light that the ADOT Core Team has identified environmental stewardship as one of three priority focus areas from a broader list of strategic planning challenges. It is ADOTs desire to strongly and proactively pursue a strategy or set of strategies that fulfill this role as an integral part of its business. Such a strategy (mix) should address matters over which the Department has formal control as well as those areas that it can influence.
The Departments role in environmental stewardship goes hand in hand with its other role to the taxpayers to deliver a transportation program on time and on budget. These are not mutually exclusive goals, nor should excelling at one mean doing so at the expense of the other. With the right mix of strategies, one can set out and succeed in excelling at both.
To develop an effective strategy (mix), focus must be placed on drawing upon effective processes from within the department as well as from outside the department. The Environmental Planning Group within the Intermodal Transportation Division and the Air Quality Programs section within the Transportation Planning Division (TPD), are currently involved in a number of leading efforts in environmental process streamlining, educational programs, performance audits, and outreach programs among others. These programs, with critical evaluation, can form a strong basis for future strategy. Some of these efforts also include on-going research projects through the Research Center. Outside the Department, other states may have identifiable programs that are already successful or that show strong potential to deliver effective solutions. Strategy elements that show promise, regardless of source, can be a part of the discussion, evaluation, and strategy development process.
Strategies in environmental stewardship ought to recognize the contributions from the many diverse role players. The most benefits will be achieved if the most players are involved and convinced to make their contribution. Those to be targeted for involvement will include:
· Local, state, and federal agencies
· Contractors in the construction and related industries
· The driving public
· The general public (as taxpayers and environmental stakeholders)
· Department employees and other state employees
1. To identify and evaluate effective environmental programs and isolate the key elements in those programs.
2. To recommend an environmental strategy or mix of strategies for ADOT as part of its strategic plan.
At a minimum, the following tasks will be accomplished by the researcher:
| 1. | Hold an initial project meeting with the Technical Advisory Committee
(TAC) to present their work plan and to solicit comments and input. |
| 2. | Review available materials on the subject to establish the state of the
practice in environmental stewardship for transportation agencies and to identify those
approaches showing the best results. |
| 3. | Hold meetings with key individuals and groups to solicit ideas on what has
worked, what will work, and how these individuals and groups could make their most
contribution. |
| 4. | Identify and evaluate approaches in environmental stewardship within ADOT
and elsewhere around the country that have proven effective or shown most potential. |
| 5. | Select elements of these approaches that together would make the most
significant environmental contribution. |
| 6. | Determine how these elements could most effectively be integrated into
ADOTs business. Focus should be placed on a continuous involvement of all
players/customers in a manner that optimizes environmental benefits. |
| 7. | Present the findings to key individuals and groups for discussion, with a
view to make necessary refinements. |
| 8. | Based on the above tasks, present a (futuristic) recommendation on the
environmental stewardship strategy (mix) for ADOT. |
| 9. | Develop an implementation plan to include marketing, financial, and
implementation schedule components. |
| 10. | Make a presentation to the Core Team / Research Council. |
| 11. | Write a final report, fully documenting gathered materials and decision processes. |
An Arizona Transportation Research Center (ATRC) project manager, working with the Environmental Planning Group (Champion) and the TPD Air Quality Team will put together a TAC and work with this committee to select and contract with a consultant to conduct the research. The Technical Advisory Committee will define the scope of work and monitor project execution by the contractor. The final recommendation and implementation plan will be presented to the Research Council and ADOT management (Core Team) for their consideration and implementation decision.
Final Report submitted July 2004 after completion of TAC review of the draft final report. Technical editing of the final report in progress.

Long-term exposure to noise is a function of atmospheric conditions that current highway prediction methods ignore by assuming a neutral, homogeneous atmosphere. Prevailing atmospheric conditions can cause receivers beyond those adjacent to a highway to be exposed to highway noise otherwise considered inaudible using standard prediction methods. This effect may not only increase audibility of highway noise but can produce noise levels that exceed the applicable noise impact criteria.
Noise emanates directly from primary noise sources such as exhausts and encased engines and from tires where the noise emissions depend upon the pavement type. Secondary noise sources arise due to reflections from pavement and vertical surfaces such as highway noise barriers. Noise barriers reflect sound energy from an elevated location and spread the highway noise over a wider area. Absorptive sound barriers offset this effect.
Negative public attitudes towards noise barriers can result from this increased noise. As an example, Ohio DOT temporarily suspended its Type II program five years ago in response to strong public criticism that arose from people whose properties were not adjacent to the highway but reported being able to hear it more clearly after walls were installed. People next to the highway still benefited from reduced noise, but more distant locations were exposed to greater highway noise.
Refraction is the underlying phenomenon that correlates with these observed (i.e. perceptible and measurable) increases or decreases of noise exposure. The refraction causes sound to follow a curved trajectory as it propagates away from the highway. As such, the effects are more noticeable at greater distances from the sound source.
The refracted sound path is fundamentally influenced by the effective sound speed as a function of height above the ground surface since sound refracts towards areas with lesser effective sound speeds. When the effective sound speed increases as a function of height, as is the case for downwind and temperature inversion conditions, sound will refract downwards. When the effective sound speed decreases as a function of height, as is the case for upwind and temperature lapse conditions, sound will refract upwards.
Over flat, grassy ground the effects of downward refraction can increase noise levels by about 0.5 dB(A) (over asphalt by about 2 dB(A)). However, when sound propagating near ground level is blocked by intervening obstacles, the introduction of refracted sound can increase noise levels by 30 dB(A). Since a 10 dB(A) change in sound levels is typically assumed to be a factor of two in changed perceived loudness, a 30 dB(A) change can be extrapolated to represent an eight-fold increase in perceived noise levels. This can negate the benefit provided to many receivers otherwise shielded from the highway.
The objective of the proposed research project is to quantify the typical non-neutral effect of refraction on highway noise, and the range of this effect, and investigate a method to screen for noise impacts.
At a minimum the following tasks will be accomplished:
| 1. | Review of literature and available data |
| 2. | Study differences between actual and neutral-atmospheric conditions |
| 3. | Assess the necessity for project specific monitoring and the utility of pre-existing regional data, such as wind roses |
| 4. | Implement prediction algorithm |
| 5. | Evaluate expected seasonal and diurnal patterns |
| 6. | Conduct two-week field measurement program during critical time periods |
| 7. | Correlate noise level variability with atmospheric parameters that control the effective sound speed profile |
| 8. | Investigate utility of a screening level design tool to identify potential noise impacts due to prevailing non-neutral atmospheric conditions |
| 9. | Document all project activity and recommendations in a Final Report. |
The Transportation Research Board (TRB) Section A1F04 on Noise has suggested that atmospheric effects remain the largest source of prediction error when the new Traffic Noise Model (TNM) predictions are compared to field measurements. R&D are required to estimate the effect of refraction on noise propagation for more typical, non-neutral atmospheric conditions. This R&D will assist ADOT in anticipating and addressing citizen concerns and allow for a better understanding of when and where increased audibility and noise impacts are, or are not, to be expected.
The preliminary screening for noise impacts due to atmospheric effects beyond first row residences will allow for greater opportunity to address citizen concerns in advance and consider the merits of additional noise mitigation, such as low-noise pavements and absorptive noise barriers. This will help increase public acceptance of highway projects.
Additional benefits to ADOT include more accurate prediction of the extent of potential noise impacts of new facilities on distant receivers, ability to study the spreading of sound by vertical surfaces such as noise barriers, and the prediction of the degradation of noise barrier performance by refracted noise.
Project is on-going with good progress made. A number of technical memoranda have been submitted to the technical advisory committee (TAC) for review. First phase of data collection was done April 2004, with second set scheduled for October 2004.

The typical strategy to reduce traffic noise near highways is the construction of concrete walls, masonry block walls, or earthen berms. These mitigation strategies are very effective for noise reduction, but sometimes result in undesired impacts, such as blocked views and large shadows across residents yards. Also, when there is a need to increase the noise reduction of existing noise walls, the standard approach is to add height to the existing wall or, many times, replace the entire wall with a new higher wall. These retrofitting approaches can be very costly.
Innovative noise barrier designs and treatments have been successfully utilized in other states and throughout Europe for a number of years that allow the initial construction of a noise wall to be lower in height than a traditional wall. Also, retrofitting an existing wall with an innovative top treatment will reduce noise levels and eliminate the need for costly wall height increases or wall replacement. Such top treatments include angled tops, irregular top edge, T-top treatments, and other applications.
The primary objective of the research is the determination of whether innovative noise barrier designs could be effectively utilized: (1) to reduce overall wall height and cost during initial construction, and (2) to substitute for costly retrofit wall height increases or wall replacement.
The research effort will begin with an exhaustive literature search of the various innovative noise barrier designs and treatments that have been used in other states and in other countries. The search will focus on designs for both initial construction and retrofit construction. The project will evaluate the economic, acoustical, and aesthetic feasibility of the innovative noise barrier designs for possible application in Arizona. An evaluation matrix will be developed to assist in this analysis.
It is anticipated that several strategies will be identified that could be effectively used in the ADOT noise abatement program. These innovative strategies will provide a cost-effective noise reduction, while reducing the aesthetic, visual, shadows, and other impacts typically associated with higher noise walls. Substantial cost savings are likely with the identification of innovative applications and top treatments that could reduce noise levels without costly retrofit wall height increases or complete wall replacement. A quantification of these costs will be part of the evaluation effort
This research effort will identify feasible innovative applications and top treatments for noise barriers that could cost-effectively reduce noise levels without undesired impacts. The ultimate implementation would be the use of these techniques where appropriate and beneficial.
Work on an RFP document in progress.

Big horn sheep occur in the area of the proposed Highway 93 upgrade and the potential exists that this population will be adversely impacted by highway upgrades. Previous studies by researchers have documented the movement of bighorn sheep across the existing Highway 93 alignment; these investigations have noted the occurrence of multiple collisions between sheep and automobiles during the years of the studies. As traffic volumes increase and the actual roadway increases in size from 2 lanes to 4 lanes, there is increased likelihood that highways may isolate resident populations of Ovis canadensis into small, disjointed herd units.
1. Identify the patterns of movement of Big Horn Sheep along this corridor.
2. Recommend measures to minimize adverse impacts during the US-93 projects construction phase.
This is the initial phase of a potentially multi-phase project to monitor big horn sheep (Ovis canadensis nelsoni) within the US-93 project area. The first phase of the proposed project will allow for the monitoring of big horn sheep with GPS equipped telemetry collars to identify the patterns of movement of the sheep. The monitoring will provide transportation officials and resource managers with a better understanding of where in the project area the natural corridors of the big horn sheep are located. This will constitute the basis for enhanced decisions on the incorporation of design features better suited to reducing or preventing collisions between vehicles and wildlife along areas of proposed improvements to Highway 93. The research will also enable resource managers to identify key habitat features that are used disproportionate to their availability and minimize adverse impacts during the US-93 projects construction phase.
The proposed research will be of direct relevance to the Environmental Planning and the Natural Resources Groups of ADOT. The work will also be coordinated with the Federal Highway Administration and other Federal, State, and local agencies including the Forest Service, the Arizona Game and Fish Department, and the Bureau of Land Management.

The use of high walls for noise abatement has become a common feature of construction in urban areas. Little is known about their air quality consequences with regard to concentrations of particulates, both from vehicle exhaust and from re-entrainment of road-surface dust. Recent work on Phoenix-area freeways has shown that coarse particulate (PM10) concentrations can be very high even on segments without sound walls during periods of low wind speed. The obstruction of winds by that would disperse particulates from freeway corridors may make this make the effect even more severe. If PM10 concentrations are found to be enhanced by the presence of high walls, then fine particulates (PM2.5) and primary emission gases such as carbon monoxide may also be enhanced and further study would be indicated.
When this research is completed, it could show that the practice of high noise walls may adversely affect air quality by concentrating vehicle-related particulates, both exhaust particles and re-entrained road dust. It could, on the other hand, prove that no significant effect is created by the high noise wall construction practices. Either result could support and guide future ADOT determinations regarding high noise wall installations.

One of the most effective methods of controlling traffic noise is to reduce the noise generated at the source. One means to accomplish this is to absorb the sound on or near the roadway. Alternative noise barrier designs and treatments have been successfully utilized in other states and throughout Europe for a number of years to address different performance needs. In some situations these designs allow for the initial construction of a noise wall to be lower in height than a traditional wall. Also, retrofitting an existing wall with an innovative top section can reduce noise levels and eliminate the need for costly wall height increases or wall replacements. However, there is no comprehensive compilation of information on such traffic noise reduction products, materials, and designs.
| 1. | Determine what noise reduction products, materials, and technologies are currently available that have potential as noise mitigation alternatives. |
| 2. | Compile available performance information and discuss whether a full-scale testing program by the department is recommended. |
Based on the results of the tasks in this project, an assessment of the expected growth in the acceptability and use of the alternative noise mitigation approaches will be completed. The nature of, and amount of available quality performance information will also be determined. Recommendations will be developed on how ADOT can best proceed on this and whether a full-scale testing program is needed. Should such a testing program be recommended, ADOT will evaluate and decide accordingly.

ADOT in the construction of highway projects over the last 10 years has transplanted substantial quantities of plant species that provide a major contribution to the area ecosystem and visual quality of highway projects. The cost of this planting on many projects can run $200,000 to $300,000 per mile. On SR 87 and US 93 heavy emphasis was placed on salvaging and transplanting of Saguaros, Ocotillo, Barrel and Yucca and some native trees. The plants salvaged and replanted on projects are watered one or two years after replanting as plant establishment. Because of the nature of the plants they may not show survival or mortality until they have been in the ground for 3 to 8 years. Since a number of plantings have been in the ground 5 to 10 years an inventory based on the projects plantings with an evaluation of survival and mortality would benefit the planning, design and construction of projects.
The salvage and replanting of plant materials can have a major visual and ecosystem effect on projects. At the present time no evaluations have been made that can contribute to our knowledge basis and towards improvement of project design. The Department annually spends several hundred thousand dollars per mile on salvaging and replanting on projects throughout the state. This would be a valuable expenditure when considering the cost for success and failure related to planting and re-establishment of these unique plants on highway projects
The resulting benefits would include the following:
| Since many of the species planted are in a time period when their survival or mortality can be determined, assessing the survival and mortality rate would provide information on species that salvage well and have a high level of survival. | |
| Research the contributing factors for survival and mortality. | |
| Develop additional criteria selection for salvage for replanting. |
1. Quantify the effectiveness and survivability of the
transplanting if native plants on highway projects.
2. Determine the level of survival and death of transplanted
plants.
3. Assess factors that contribute to survival and mortality of
transplanted plants.
4. Review information for improvement of projects requirements
ADOT has a number of projects now reaching an age where salvage and replanting materials could be evaluated to provide effective determinations. An evaluation of salvage techniques and establishment techniques would enable the Department monies to be spent more effectively.

Habitat fragmentation by highways generally creates species declines. For bighorn sheep, size of contiguous habitat is a critical factor determining population persistence. Arizona consists of 32 isolated bighorn sheep ranges of varying sizes, the Black Mountains in northwestern Arizona being the largest (>500,000 acres). The range contains the largest desert sheep herd in the U.S., and represents 31% of Arizonas sheep population. The Black Mountain herd also provides an important source population for transplants. Upgrades to SR 68 and U.S. 93 could create three smaller isolated patches of bighorn sheep habitat in the Black Mountains
Highway underpasses are used nationally to mitigate the effects of habitat fragmentation, yet few performance evaluations have been conducted (Foreman et al. 2003). Two underpasses were installed in the Black Mountains along SR 68 for wildlife crossing; however, their effectiveness remains largely unknown. Little is known about bighorn sheep use of underpasses elsewhere, or the factors that influence sheep use of crossing structures. Information is needed to ensure proper placement and design of passages on this and future highway projects planned in the Black Mountains.
| 1. | Quantify the effectiveness of SR 68 highway underpasses in facilitating bighorn sheep habitat connectivity in the Black Mountains. |
| 2. | Determine physical and biological factors that influence bighorn sheep use of these underpasses. |
| 3. | Recommend modification to wildlife crossing structures if necessary |
With the results of this evaluation ADOT will be able to make informed decisions when opportunities arise during maintenance and new roadway constructions, for the upgrade to and installation of wildlife crossing structures of proven effectiveness.

ADOT recognizes that with the construction of highway projects and to waters of the U.S. and important habitat areas that there is an opportunity to re-establish and enhance quality wildlife habitat areas. The present Permits frequently require planting on a replacement of 3 to 1 with up to 80% survival in the fifth year of the permit. Based on review of these permit areas it is becoming apparent that these requirements are beyond a naturally sustainable level with a number of projects falling short of these requirements. Since habitat and native planting has not been studied these criteria are based on assumptions beyond what the various ecological systems appear to be able to support especially in a drought.
The present 7 year drought that we are experiencing has a very direct effect on the survivability of the plantings. At the present time no one area can provide information from which to make evaluations and determinations which would provide a basis for new project plantings and specifications. Values that are appearing with projects require additional time and effort of the various staff resources in setting up new projects and addressing value issues.
The resulting benefits would include the following:
At the present time we estimate ADOT spends over several thousand dollars a year for plantings on various projects throughout the state. Evaluations 3 or 4 years after these plantings are being made are beginning to indicate that many of these plantings are being made beyond the naturally sustainable level. The research would provide additional direction to the Department on realistic expectations and commitments.

This Intelligent Vehicles (IV) project was the result of ADOT visits to the National Automated Highway Systems (AHS) Demonstration in San Diego, California in 1997. The project concept is to evaluate ITS driver assistance and guidance technology for maintenance vehicles in severe winter storm conditions.
The Arizona Transportation Research Center (ATRC) is conducting this project in-house. Six winters of testing and evaluation have now been completed. Phased project reports were published by ATRC in February 01, May 02, September 03 and January 04. The ATRC will continue to monitor implementation and field evaluation of IV snowplow systems.
The key objective of this ongoing project is to continue, and to implement, advanced snowplow research. A second objective is to pursue further research into intelligent vehicle systems, as it may eventually lead to deployment of advanced vehicles and dedicated lanes in Arizona.
This ongoing project will identify promising areas for deployment of ITS-IV systems in Arizona. It will support further research, tests and demonstrations as warranted in the areas of dedicated lanes, vehicle guidance and related technology. The current focus is on validation of new technologies to improve safety and efficiency of winter maintenance in Arizona conditions, and to promote implementation and further local evaluation of these systems.
Initial project efforts evaluated Intelligent Vehicle technology for congestion relief. A concept study was done on dedicated AHS lanes on I-10 from Phoenix to Tucson. A demonstration of magnet-guided, fully automated cars was conducted in late 1997 on a closed course in Tempe. Another on-highway demonstration in early 1998 employed cars with machine-vision guidance.
ADOTs Intelligent Vehicle research goal is to enhance travel safety and operational efficiency, and the current focus is winter maintenance. In 1998, ADOT joined the California Department of Transportation (Caltrans) to evaluate a prototype Advanced Snowplow (ASP), the Caltrans RoadView system. ADOT began tests of the Caltrans magnets in early 1998, and a six lane-mile test site was constructed on US 180 near Flagstaff in 1998 and 1999. The Caltrans ASP vehicle was shipped to Arizona for one month of training and testing each winter, for four years.
In early 2000, after two years with Caltrans, the research TAC directed that driver-assistance systems be installed on an ADOT snowplow. As a result, the 3M Company equipped a truck and installed five miles of magnetic tape on US 89 near Sunset Crater. Winter testing of this 3M Lane Awareness System in 2000-01 and 2001-02 was a success.
After four years of extensive training and evaluations of the Caltrans and 3M guidance systems, the TAC shifted the research to less complex commercial on-board warning systems for low visibility conditions. It was clear that the roadway-infrastructure systems were too costly for ADOT, and the TAC concluded in early 2002 that true whiteout storm conditions were not frequent enough in Arizona to justify the advanced, semi-automated systems.
The TAC requested that the project study two commercial on-board warning systems for low-visibility conditions Eaton VORAD Collision Warning Radar and Bendix XVision infrared night vision. ATRC acquired four radar and three night vision systems. Seven maintenance camps in three districts were each provided with a test system for one of their snowplows, and all were installed by January 2003. The 2002-03 winter was quite mild and dry, with only limited snowplowing results for the winter. This was considered the last winter of research, as it resulted in a regional deployment. A final project report 473(4) was published in January 2004 on the concepts and issues encountered with the 02-03 deployment of on-board warning systems.
This research program continued for another winter in an implementation evaluation mode. ATRC was able to complete a full winter of testing and evaluation in 2003-04, although it was yet another dry season for northern Arizona. Results of this just-completed second winter will be summarized for the TAC in a brief technical memorandum.
While the research activity is complete, the project will remain fiscally active for a third winter, in support of further implementation, operational use, and possible maintenance of the on-board warning systems on seven snowplows across northern Arizona.

A variety of independent ADOT systems currently monitor and report traffic activity, as well as roadway and weather conditions across Arizona. This range of field data includes traffic counts, weather data, signal timing, Variable Message Sign (VMS) displays, video signals, and the web-based Highway Condition Reporting System (HCRS) dynamic database.
Data formats vary, and the full range and detail of this valuable information is not consistently available to ADOT managers at state and district operations centers and in the field. There is a vital need to consolidate these key dynamic data sources and to provide consistent, user-friendly, one-screen access for more effective big-picture management of the states highways. The goal of the research is to provide direct links to these programs from the HCRS operator screen.
A related urgent need is to deliver critical real-time information on highway conditions and roadway operating decisions to the public. Location, range, cost or other constraints can limit real-time traveler information. A second key goal of this project is more timely, accessible, and reliable traveler information for the public.
The objectives of the project are:
The consultants workscope involves the following tasks:
The primary goal to consolidate roadway data sources will be implemented as soon as possible with the web-based HCRS system already in use statewide. This project will develop valuable new tools for operational management of the highway system by and among the Districts, and, for better rural delivery of critical traveler information.
The consultant, OZ Engineering, had a major role in developing the web-based ADOT Highway Condition Reporting System. Initial goals were substantially completed in 2003, to consolidate the three primary data systems (VMS, cameras, and weather data) with HCRS. As some project budget remained, a proposal was requested for a second level of traveler-information and HCRS operational upgrades. This work was approved and user-friendly enhancements for HCRS were added to the scope with a $15,000 funding increase. However, the new work by OZ was delayed due to third-party problems with the delivery of other high-priority HCRS data systems. As a result the 512 project was delayed until April 2004, when work on final tasks was resumed. The draft Final Report has also been initiated concurrently.

Railroad grade crossings create traffic control problems that severely impact traffic flow. Safety problems occur in urban areas when a street that feeds into a parallel arterial has a grade crossing near that intersection. Here, the left and right-turn arterial stacking lanes may overflow onto the parallel arterial mainline as a passing train blocks the minor street. At Flagstaff, this condition exists on SR 89 / Route 66 at the Enterprise Road intersection, with more than 85 trains per day.
Similar safety problems occur in semi-rural areas where grade crossings for feeder roads at freeway interchanges lead to long blockages of peak hour traffic, causing severe congestion. Even worse, overflows of queued vehicles onto the freeway mainline can occur as ramp capacity is exceeded. Smaller towns as well as larger cities have these problems and both the Pima and Maricopa County metropolitan areas recognize the issues and support the search for remedies.
In many of these cases, where highways and railroads are parallel, ADOT manages the affected traffic signals. ADOT currently has approximately 30 traffic signals with train preemption. Increases in both train traffic and vehicular traffic are predicted, as Arizona continues to grow.
This project will develop site-specific, enhanced train clearance algorithms that can provide significantly more green time, before the arrival of a train, to reduce overflows and congestion.
ITS technology can monitor train speed, acceleration, deceleration, and length far in advance of current systems that give a minimum 20 seconds of warning time. This data can enable new site-specific prediction models of train arrival times and crossing durations. Operating in real-time, the models can provide very early predictions to intersection signal controllers. Variable Message Signs can also communicate this real-time information to motorists.
The hardware for this ITS application already exists, and existing microscopic simulation software can be modified to provide real-time traffic data for individual vehicle movements, enabling an actuated controller to control the site signals. This software-hardware interfacing, or hardware-in-the-loop simulation, is an effective prototyping tool. These site-specific ITS prototypes can be rigorously evaluated using multiple Measures of Effectiveness. Hardware-in-the-loop simulation, with site-specific prediction models and control algorithm development offers ADOT a very high level of risk reduction for deployment in the future.
The following phases of research will be performed:
1. Sites selection, development of off-track detection
methods, and site data collection.
2. Development of site-specific train arrival prediction
models.
3. Prototyping ITS signal processing and microscopic
simulation of site traffic.
4. Hardware-in-the-loop prototype development, site-specific
controller algorithm development.
5. Total system prototype validation using second data set.
The only effective solution currently is grade separation structures, but the need and the cost far outstrip ADOTs ability to build them. The result of this applied research will be a congestion-mobility management tool for these situations, as growth continues and as traffic increases.
This project will benefit both the public and ADOT with regard to safety and to congestion-mobility management. Benefits of future application of this research will include:
This project was initiated through a JPA with the University in March 2003. Acquisitions of equipment, modeling software training, and field data collection were initial activities. VISSIM model development has been completed and signal control scenarios are being developed to establish the critical proof of concept, and thus to consider additional test sites in a second phase. Note a Phase 2 proposal was not approved for FY 05 by the ADOT Research Council.

Communication is the key to all ADOT operations and emergency response roles in both rural and urban areas of Arizona, from daily maintenance to events to incidents to regional security issues. Currently no single radio frequency allows for all responder groups to talk to each other. A critical need exists for secure cross-channel communications, on the present radio systems, both within ADOT and with its transportation agency and emergency response partners of all levels. Radio interoperability technology can overcome the lack of a common frequency, channel, or system between response team agencies, and across jurisdictional boundaries.
Homeland security concerns have created a new incentive, and new resources, to address key communications issues at all levels through strategic plans and interagency partnerships. However, the critical focus on homeland security must not downplay transportation-specific concerns. This Phase 1 communications systems research project will address current specific challenges of radio interoperability for ADOT and for its transportation-agency partners.
Overall, this programs objective is to enhance ADOTs performance in homeland security, enforcement, roadway incidents, and operations, by improving interagency communications. This Phase 1 Needs Evaluation will assess the current ADOT capabilities, constraints, problems, practices, and equipment in detail, and will also do the same for ADOTs partner agencies.
One key goal is to develop an Arizona database of current radio systems, frequencies, hardware, software, and operating plans currently in use by local and regional transportation agencies. This information will support ADOTs strategic planning, and also its effective coordination with the larger communications upgrade programs being developed at the state level specifically for homeland security.
A second key goal is to review and recommend the best interoperable system configurations and processes for Arizonas rural transportation system. ADOT is always a primary responder, and it sometimes is the lead agency for incidents, events and operations of all types. This project will recommend whether a central, regional, or district-level system, or some combination thereof, would best support both ADOTs internal needs and its partnership responsibilities. The effort will include the development of test plans to validate the recommendations under the variable communications conditions found across rural Arizona.
ADOTs Kingman and Flagstaff Districts and the ADOT Homeland Security Task Force are joint sponsors for this project, with technical and advisory support from Arizona DPS.
This project will define effective transportation interoperability in remote rural conditions across Arizona, and it will support ADOTs planning, and future tests and deployments, for operations and for local and regional incident response and command.
This project conducted a series of six workshops in rural districts across Arizona, involving both ADOT field forces and partner agencies. A database was developed including agency contacts and the details of radio systems and operational practices. The project has developed near- and mid-term recommendations to improve ADOTs operational communications, including several near-term pilot projects to validate these concepts. Reviews of the final report are in progress.
Project Champions are Lonnie Hendrix and Tim Wolfe (for ADOTs Homeland Security Task Force), with the Flagstaff & Kingman Districts. ADOTs Homeland Security Communications Subteam serves as the project TAC.

The proportion of the population over 65 is expected to double by 2040. Elderly drivers are an increasing element of the population, and with advanced age come increasing challenges to safe and efficient travel, and overall mobility for the individual. As the proportion of elderly citizens increases, it will be important to take advantage of every opportunity to enhance the driving ability of older drivers. Research has been conducted nationally into the needs of the elderly for Advanced Traveler Information Systems (ATIS), as well as the special characteristics of the elderly that may impact Intelligent Transportation System design and deployment. Key findings of earlier studies with regard to elderly drivers include:
However, very little research has been conducted into the elderly communitys reaction to such overall ITS program implementations as ADOT has deployed in metro Phoenix (CCTV cameras, Variable Message Signs, traffic detection, signal coordination, ramp metering, the national 511 system, and web-based traveler information). If ITS is planned and deployed effectively with regard to the concerns and limitations of the elderly drivers, the potential increase in roadway safety could be quite significant.
The acceptance and utilization of ITS by older drivers will be an important factor influencing future ITS implementations in those areas with concentrated and expanding elderly populations. One such potential study site would be in the West Valley (Loop 101, Bell Road, Loop 303, and Grand Avenue). Other sites and elderly populations in the East Valley will also be considered, in order to achieve balanced results from across the metropolitan region.
RESEARCH OBJECTIVES
The objectives of this project are to identify the level of elderly travelers satisfaction with ITS implementations on ADOT facilities, in particular the variable message signs, ramp meters, and traveler information systems, and to recommend potential improvements in operation and design. The primary project elements would be:
This research will help develop transportation strategies to improve the overall efficiency of the transportation system with regard to significant elements of the driving population. Information is essential to inform decision-makers at all levels federal, state and local on issues regarding ITS acceptance by the elderly population. The process owner is the Transportation Technology Group of ADOT, who ultimately would determine how the research results will be integrated into the states ITS planning and operational activities.
This project is in progress. The total project budget includes a 50 percent contribution by Maricopa Association of Governments.
Over the 2003-04 winter, mature-driver focus groups were conducted in both the eastern and western regions of the Phoenix metropolitan area. Also, a control group of younger drivers was similarly involved. A key area of this research is to evaluate ADOTs 511 traveler information system and its linked az511.com website. Due to progressive updates of the phone system and the website, limited follow-up evaluations are planned as the project approaches completion. At the same time, however, work is under way on the draft project final report.

Communication is the key to all ADOT operations and emergency response roles in both rural and urban areas of Arizona, from daily maintenance to events to incidents to regional security issues. There is currently no single radio frequency to allow all responder groups to talk to each other. A critical need exists for secure cross-channel communications on present radio systems, both within ADOT and with transportation agency and emergency response partners at all levels. Radio interoperability technology can overcome the lack of a common frequency, channel, or system between response team agencies, and across jurisdictional boundaries.
Homeland security concerns provide a new incentive, and new resources, to resolve Arizonas communications issues at all levels, through strategic planning and interagency partnerships. Interoperability is a statewide need, both for incident management and in Homeland Security situations, and is the core goal of a long-term (2010+) communications strategic planning effort by the Public Safety Communications Committee (PSCC) and the Department of Public Safety.
However, the critical focus on homeland security must not downplay transportation-specific concerns. This Phase 2 communications systems research project will evaluate near and mid-term operational interoperability solutions for ADOT and for its transportation-agency partners.
This program, in two phases, seeks to enhance ADOTs performance in homeland security, enforcement, roadway incidents, and operations, by improving interagency communications. This new Phase 2 Resource Planning project will build on the results of the current SPR-561 Needs Assessment research (Phase 1) with regard to the current status of ADOT transportation communications, the radio frequencies and systems currently in use across the state by partner agencies, and ADOTs priorities as defined for near-term solutions.
This new project will evaluate near- and mid-term solutions for the day-to-day communications constraints and agency issues in the statewide transportation environment. It will also seek to coordinate these potential solutions with the statewide interoperability plan and development schedule as determined by the PSCC, as well as other Arizona homeland security programs.
Through a series of small-scale local pilot projects, this Phase 2 research will validate the near-term recommended communications enhancements for ADOT and its core partners, based on the Departments statewide roles, needs and responsibilities. The regional pilot deployment efforts, if successful, will form the basis for statewide ADOT radio system upgrades that may be enabled with Homeland Security resources. Future implementation strategies at multiple levels will also be refined, based upon the potential availability of funding grants from various public safety and security resources.
The transportation communications resources to be evaluated in this Phase 2 project will enhance both day-to-day and emergency operations, and effectiveness, for ADOT in its key roles. It will provide better field communications in the selected pilot project areas, and will therefore justify near-term statewide applications of the key Phase 1 recommendations.
A key benefit of this project will be more timely and effective ADOT responses in all multi-agency emergencies, and better fulfillment of critical ADOT obligations in homeland security. It will also help to develop common goals and procedures among other transportation agencies and key partners in the State, with regard to improved operational effectiveness in all areas.
Enhanced field and regional communications will enable better decisions, faster response, more efficiency, and more lives and property saved in all situations both in any crisis, and, in all day-to-day activities.

In December 1998, ADOT completed Research Project SPR-457, a Strategic Plan for Statewide Deployment of Intelligent Transportation Systems. Since Arizonas statewide ITS design was completed, there has been an extensive deployment of the most critical systems in the plan. Now, after more than five years of implementation, the need exists for ADOT to review and to evaluate the key ITS concepts and hardware that are being used in rural Arizona on a wide scale.
The Kingman District in particular has been a key location for the early deployment of ADOTs new ITS concepts, with the I-40 Corridor and the US 93 NAFTA (North American Free Trade Agreement) Corridor meeting in Kingman. Hoover Dam and other Colorado River crossings are also critical to commerce and to national security. Also, in addition to the statewide plan, several other new ITS programs are being tested for the first time by the Kingman District, and these may be significant for the rest of Arizona. This district will therefore be the primary area of focus in this statewide evaluation project.
There are four primary goals for this Arizona rural ITS evaluation project:
An evaluation program will be developed to assess the performance of the key rural ITS systems used in rural Arizona. The study will review the results for each key system, as regards costs, benefits, reliability, and level of meeting client needs. It will then evaluate these individual technologies as integrated operational resources for management of the state highway system.
The project will involve a variety of outreach efforts, to include focus groups, mail, e-mail or phone contacts, and interviews. The primary emphasis will be on ADOT staff and key partners at several levels, with a secondary focus on the traveling public. Internal contacts will focus on reviewing systems status and performance issues at the state, district and local levels. Traveler contacts will assess the publics perceptions of ITS, and the related travel information as provided by ADOT and by other agencies.
Currently-deployed ITS-based elements in the study, as prioritized by the project TAC, include: VMS, HCRS, remote video cameras, Road Weather Information System (RWIS), the AZ511 travel information system, and the Statewide Incident Management Plan.
The project will primarily focus on the Kingman District. In addition to the above systems, this District also has tested many other innovative ITS-related concepts including portable VMS, Motorist Assist Patrols, emergency callboxes, truck escape ramp intrusion sensors and cameras, travel time monitoring with license plate readers, and Highway Advisory Radio.
This research project will evaluate and report on the performance of the statewide rural ITS system, with the main emphasis on northern Arizonas I-40 Corridor, where ADOT previously carried out an early deployment plan. Other less ITS-active rural highway corridors will also be reviewed for comparison, such as US 60, US 89, I-10, I-17, SR 87 and/or SR 260.
The significant value of this research for ADOT lies in validating the investment in current Rural ITS systems and concepts, and in identifying potential improvements for the future. This research will provide a detailed performance assessment of the critical systems, and of the overall ITS benefits to highway operations. It will enable better application of future resources, and may offer new ways to enhance the effectiveness of the current systems.
STATUS OF THE RESEARCH
This project was initiated in April 2004, and is conducting workshops in each ADOT district to assess the extent of use and the effectiveness of the systems deployed to date. Further data is being sought through public surveys, including a link from ADOTs AZ511.com website.

Snowplow operators face the most demanding set of operating tasks in the worst weather and traffic conditions. They work long and stressful shifts in snowstorms at any hour of any day throughout the winter. ADOT operators must not only drive a $250,000 snowplow, they also must operate spreader and plow controls, monitor the trucks instruments and radios, and stay focused on the weather and highway surface conditions and on the traffic around them.
Current operator training, with limited budgets and manpower shortages, often consists of sending out new drivers into winter storms with a partner-mentor-trainer for only a few work shifts, at best. For this level of skill and responsibility, such training is just marginally adequate.
ADOT will conduct a pilot program of snowplow operator training with new state-of-the-art simulator technologies. This research will test the effectiveness of realistic situational driver training in a safe off-highway environment. Simulator training can build decision-making skills for emergency situations before the operators are sent out alone on the roadway in a snowplow or other heavy vehicle. The significant investment in equipment justifies the development of an improved, more effective training program.
ADOTs Highways Division training staff will contract the training services for the pilot project from the snowplow-simulator system developer. The goal of this evaluation research project is to support and document the simulator training activity, and the long-term snowplowing safety record of the pilot program trainees. The primary task elements of this research effort are:
The results of this research will justify and support the future establishment of training-simulator facilities by ADOT for its equipment operators, both for the States critical snowplow operations and with the potential to support other types of heavy equipment training. Future options for ADOT may include the purchase of simulators, a lease program, or ongoing vendor services.
Improved driver skills and confidence will enhance safety for ADOT equipment operators. This in turn will provide better road conditions, improved driving safety, and enhanced schedule reliability both for the motoring public and for time-sensitive commercial freight operations.
Equipment operator retention may be measurably improved if better training enhances skills and confidence. This may reduce overall driver stress levels, increase job satisfaction, and improve performance in emergencies. Further significant value may be derived from reduced crashes and incidents involving ADOT fleet units and the public.

ADOTs Freeway Management System is designed to apply smart ramp metering, taking into account the impacts on mainline freeway traffic flow. However, since its inception, smart real-time traffic-adaptive ramp metering has never been implemented.
Planned FMS controller upgrades, and existing communication infrastructure, would allow the full utilization of new ramp metering control strategies, such as the U of As traffic-adaptive MILOS program, on extended freeway corridors. Such smart corridors will make ramp-metered traffic flows smoother and improve the operation of system interchanges and connecting corridors in the region. This projects corridor simulation modeling would validate the traffic-adaptive concept (this Phase 1), and will justify its early implementation when the FMS is upgraded (a Phase 2 effort, should it be shown beneficial in simulations).
ADOTs Transportation Technology and Traffic Engineering Groups will support the research effort in coordination with planned near-term Freeway Management System upgrades, as well as new FMS construction, in the Phoenix metropolitan area. The objectives of this research phase are three-fold:
This research will enable the full utilization in the near future of traffic-adaptive concepts and capabilities for which a platform is already designed in the ADOT FMS system. Significant benefits including reduced congestion, reduced emissions and improved safety.
This project will establish the basis for field evaluations of the most promising smart ramp metering system, when the planned hardware upgrades have been completed for the Valleys Freeway Management System.

The Strategic Highway Research Program (SHRP) investigated the cost effectiveness of several pavement surface treatment alternatives. However, the resulting data and analysis have not provided needed techniques and information for developing and promoting cost-effective pavement maintenance strategies.
The effectiveness of many maintenance activities such as pothole repair, crack sealing, flushing, surface treatments, etc., vary from area to area and their performance is difficult to quantify at a network or project level. In addition, considerable use of asphalt rubber is occurring by the Arizona Department of Transportation (ADOT). The preventive maintenance activities such as flushing, patching, etc. could be significantly different for these roadways. ADOT needs to establish procedures for the effective treatment of these products.
Many proprietary products have potential for providing cost-effective maintenance treatments. However, low-bid procurement processes often inhibit the use of these products due to the lack of information available to develop justifications based on public interest." Additionally, innovative contracting procedures such as warranted work are currently difficult to implement. Evaluation of the current laws and procurement procedures are necessary to determine how some of these other alternative procurement processes can be utilized.
The objectives of this project are to: (1) identify the maintenance surface treatment alternatives suitable for evaluation by ADOT, (2) develop a consensus on which alternatives to test, (3) determine the performance and cost effectiveness of these treatments, and (4) identify procurement issues which inhibit effective pavement maintenance and recommend solutions to these issues. This will be accomplished by developing an experimental design and constructing and evaluating test sections.
At a minimum, the following tasks will be accomplished:
The project will provide life cycle surface treatment comparisons that can be used to select maintenance strategies and for cost effective surface treatments for new construction.
One hundred ninety three test sections have been constructed. An additional 84 test sections were to be constructed in the fall of 2002 but the construction project was cancelled. The project is being conducted in three phases: Phase I Wearing Course Experiment; Phase II Surface Treatment Experiment; and Phase III Sealer Rejuvenator Experiment. Phase I and II is complete. Phase III, which is being conducted in conjunction with the FHWA National Sealer/Rejuvenator project, will have a total of 60 70 test sections placed in addition to the 193test sections constructed in support of phase I and II. The participating states are AZ, AL, CA, MN, and MI. Phase III test sections have been placed on SR 87 near Winslow and a second set will be place on US 93 near Nothing, Arizona. The second round of sealer-rejuvenator applications will occur in July-September.

In the rural areas MC-250 is the product of choice for filling potholes, fixing road base failures, and providing level-ups. Often times MC-250 is mixed with locally available aggregate on road tables and blended at the maintenance yard. It is then stockpiled for up to six months to a year and used as needed. At other locations, the MC-250 is obtained from commercial sources and stockpiled for future use. MC-250 cold mix is very inexpensive when compared to other types of paving and patching materials.
Commercially available alternatives to MC-250 are typically significantly more expensive (perhaps three to four times more expensive), or they did not have an adequate shelf life to remain in storage for a minimum of six months.
MC-250 contains volatiles that exceed the air quality standards for Volatile Organic Compounds (VOC) and is no longer used in the active enforcement areas. Although still permissible in some areas, it will eventually not be an option.
There is a need to find an alternative material(s) for MC-250 or alternative ways of doing business. For example it may be possible to obtain commercial materials so that there is not a need to stockpile for any more than two to three months. This might make it possible to use other materials that are not now considered acceptable. Similarly other techniques for leveling may be considered
The objectives of this research are to establish products and or processes that can replace MC-250 for its intended functions.
The minimum following tasks will be performed:
The products and or processes recommended in this study will be used to replace MC-250 for all of its current uses.
New Mix Design procedures, based on the Asphalt Institutes MS-14 methodology, were implemented for the 2004 cold mix procurement. Field evaluations of the cold mix production are on-going.

The Arizona Department of Transportation (ADOT) pavement management system (PMS) is used to allocate expenditures on pavement preservation. Data is collected annually on roughness, skid, cracking, rutting and flushing. This data is entered into the PMS system to allocate resources and to provide input into the pavement design function. One of the data fields that the PMS uses in project selection is the average maintenance expenditure per year. The expenditure is obtained from uploading data from the PECOS system.
The PMS system provides a continuous database of pavement performance for the state network.
Maintenance activities, such as preventive maintenance, are all recorded in the PECOS system. PECOS is a resource allocation system that tracks labor, materials and equipment. It does not track the outcome of the activity such as pavement performance for preventive maintenance activities.
There currently is no maintenance process by which outcomes, such as improved pavement performance, can be measured except through personal observation by the individuals applying them.
There is a need to develop a system that allows evaluation of the outcomes of maintenance activities so that their cost effectiveness can be determined and used in development of pavement preservation strategies.
The objective of this research is to develop a process that provides the ability to measure the outcomes of the pavement related maintenance activities.
The minimum following activities will be performed:
The product of this a new PMS system for the Department that will support both the PMS for materials and the preventive maintenance program for district maintenance.
The new PMS has been installed and has begun its two year warranty period.

For the greater part of the interstate construction program, the Arizona Department of Transportation (ADOT) maintained the responsibility to locate acceptable aggregate sources for construction purposes. ADOT would locate sources of material, obtain all clearances and permits and perform the geotechnical analysis of the pit composition. At one time, ADOT maintained a database of over 8,000 material pits located around the state. This process made ADOT liable for material acceptability and often times resulted in claims from the contracting industry based upon misrepresentation of the character or quantity of material involved.
In more recent times ADOT turned over the material source issue to the contracting sector. The contractor currently is responsible for locating and obtaining pits for each individual construction project. This makes the contractor entirely responsible for his quality and quantity of material obtained.
Recently, material sources are becoming increasingly more difficult to find and use, even for the private sector. Many of the material sources in northern Arizona are located within reservations and the Indian nations have been less willing to allow access and use.
The lack of material availability is even affecting aggregate sources for maintenance use. There is a need to provide reliable aggregate sources for construction and maintenance activities.
The objective of this research is to identify the aggregate sources available for construction and maintenance in northern Arizona and to determine the means by which these sources will be used.
The following minimum tasks will be performed:
The results from this research project will establish the aggregate sources for construction and maintenance activities in Northern Arizona.
This project will be piggy-backed upon a previous effort by the state land department. Efforts are underway to form a new TAC and begin prosecution of the project.

A significant number of the Arizona Department of Transportation (ADOT) bridges are twenty years and older. As these bridges age they deteriorate as a result of load related damage and from environmental damage such as freeze thaw action, sulfate attack, ASR activity, de-icing chemicals, etc.
Although the behavior of these environmental stresses is well documented, the detection and mitigation are difficult at best. It oftentimes requires sophisticated equipment and special materials.
Normal maintenance activities usually do not include repair to structures. However, as ADOT's aging structures become older and older repairs become more and more common. There is a need to provide both training and procedures for repairing bridge decks.
The objective of this research project is to develop procedures and training materials for repair of bridge decks by maintenance forces.
The minimum following tasks will be performed:
The results of this research would be used in working practice by ADOT's maintenance personnel.
The project has been re-scoped to develop a bridge preservation program process that includes, among other things, repair procedures. The project will identify the items to be considered in the preservation program, and develop specifications for each of the preservation work items to be contracted out. The bridge group, materials, and central maintenance are collaborating together to develop the work items, specifications, and contracting procedures.

The Arizona Department of Transportation (ADOT) has traditionally placed an open-graded Asphalt Concrete Friction Course (ACFC) on all interstate and high volume roadways. Over the last ten years the department has changed from predominantly using ACFCs to using Asphalt-Rubber/Asphalt-Concrete Friction Courses (AR-ACFCs). These materials are installed as the final roadway surface and are what vehicle tires contact. These open graded materials are somewhat porous and are designed to drain the roadway surface quicker. As a result, they provide better wet-weather friction, better stripe delineation and produce less glare from headlights during inclement weather. They are also generally quieter than conventional dense graded mixtures.
Since these materials are somewhat porous, they cannot be repaired using conventional hot mix or cold mix materials that are typically non-porous. When non-porous materials are used, they behave as a dam within the AR-ACFC, trapping water and accelerating its deterioration. Currently there is no readily available material to repair AR-ACFC surfaces effectively. There is a need to develop and evaluate materials suitable for repairing AR-ACFC surfaces.
ADOT currently has an ongoing research project, SPR 459, to develop Environmentally Acceptable Materials as a Substitute for Cold Mix. The asphalt binders studied in this effort can be used for application to the open graded materials. However, there is a need to evaluate whether their performance will be acceptable.
The objectives of this task are to develop/find materials for repairing AR-ACFCs and ACFCs and evaluate their acceptability for maintenance repairs.
The following tasks, at minimum, will be accomplished:
If the research is successful, implementation would be immediate. The products developed in this research would be used by ADOT maintenance to repair open graded friction courses.
This project will be developed concurrently with SPR 459

Plowing snow is very difficult, but very necessary. Poor weather reduces visibility. This problem is further exacerbated by the need to mount headlights higher on the equipment so they shine over the plows. This often results in the plow lights being almost at the operators eye level, which is the worst condition for reflecting light back into the snowplow drivers eyes, obscuring their vision even more. This headlight position also reduces visibility for on-coming traffic since the headlights are higher than normal. The additional colored beacon lights that are used on plows as warning devices also reflect off of the snow into the operators eyes. Although these lights are mounted behind the driver, they still reflect off the snow and obscure vision. Other problems that exist during plowing operations are the visibility through the windshield due to fogging over and the effectiveness of the wipers themselves.
A recent informal survey was conducted at the last maintenance workshop. Of the 50 to 100 respondents, not one operator felt that snowplow visibility was adequate. This is an alarming statistic since clearing of the roadway is the most significant safety improvement the Arizona Department of Transportation (ADOT) can make for the traveling public.
In addition to the reduced vision caused by these problems, increased driver fatigue is experienced. Since plowing snow is such a difficult event, anything that contributes to additional fatigue should be minimized or eliminated.
This problem was the focus of a recently completed National Cooperative Highway Research Program (NCHRP) study that made recommendations for improvements. ADOTs previous study on Winter Storm Operations also made recommendations to improve plow operations. However, no recommendations to improve lighting configurations have been provided to eliminate the problems described.
The objective of this research is to increase operator visibility and to reduce glare to on coming traffic during plowing operations.
The following tasks, at minimum, will be accomplished:
The results of this research would be used to modify ADOTs snowplow fleet.
A prototype light support system has been developed in-house to boom lights beyond the plow in front of the plow. The proof of concept work indicated significant advantages to the lighting approach. The durability of the lighting system was not acceptable however. Accelerometers were placed on the plow during dry pavement operation to measure the actual accelerations experienced. A modification to the light fixture attachment will be made for testing in the fall of 04.

The American Association of State Highway and Transportation Officials (AASHTO) is currently developing a new pavement structural design guide that will be available in draft form in 2000/2001. The new AASHTO pavement structural design guide will be a mechanistic based design procedure. This form of pavement design (i.e. mechanistic design) has not been used by the Arizona Department of Transportation (ADOT) previously. This type of design process is technically more challenging and requires a higher degree of knowledge on the pavement design engineer as well as a more sophisticated approach to materials testing and characterization.
At this same time, the Federal Highway Administration (FHWA) is attempting to complete the Strategic Highway Research Program asphaltic concrete (AC) mixture design process with additional ongoing research. This research will develop a simple performance test and provide models and advanced materials characterization tests.
Both of these studies will significantly alter the methods by which AC structural design and mixture design will be performed. The principal investigator on both of the above referenced research projects is Dr. Matt Witczak a professor at Arizona State University (ASU). To prepare ADOT for implementation of the above referenced research, ADOT and ASU have developed a five year strategic pavement research effort. The first year of this effort was funded with SPR 402 "Long Term Pavement Performance (LTPP) Superpave Implementation".
The overall objective of this continuation project is to implement a methodology for performance related specifications for asphalt pavements in ADOT. The short term objective is to leverage the ongoing research activities of AASHTO and the FHWA into Arizona design practice.
The minimum following tasks will be performed:
This is research is designed as a five year program intended to fast forward the implementation of the 2002 AASHTO Pavement Design Guide. Implementation of various technologies will occur as the research validates that the technologies are appropriate for Arizona use and implementation into practice.
The project is essentially complete. Awaiting delivery of the final report.

The national trend away from new construction to preservation of the highway system is requiring highway agencies to seek alternative approaches to pavement preservation. One option which has seen considerable increase in use is recycling. Although pavement recycling is reported to have been done as early as 1915, its principal use has been since the mid-1970s. Recycling consists of both hot and cold recycling which can both be done in place or off site.
Cold in-place recycling has seen ever-increasing use in recent times due to improvements in technology, longer performance records, and greater emphasis on quality control. Cold in-place recycling is generally referred to as full-depth or partial-depth recycling. Partial-depth recycling is more prevalent and generally consists of rehabilitating the top 2 to 4 inches of the pavement structure. Some agencies require the placement of an overlay or wearing surface on top of the cold recycled material while other agencies allow cold recycle as the final wearing surface.
Partial depth, cold in-place recycling is an attractive option for use in Arizona, particularly with the remote locations of many highways. Unfortunately, there is not a single, nationally recognized design procedure. Instead, many procedures have evolved based upon experience and varying design philosophies. Two major theories have been promoted for designing cold mix materials. The first is to consider the salvaged material as simply black aggregate with some hardened asphalt coating and to design an asphalt content to coat these particles. The second theory considers the asphalt present in the salvaged material as part of the future binder design. This approach evaluates the physical and chemical aspects of the salvaged binder and adds a rejuvenating agent to restore the reclaimed asphalt to its original condition as well as adding additional binder for coating of the aggregate. Recent efforts have indicated that perhaps the actual phenomenon is somewhere between these two theories.
Many different binders can be used in the cold mix process. Typically, binder contents range from 0.5% to 1.5% of emulsion for partial depth, cold in-place mixes. Medium setting and high-float emulsions and emulsified recycling agents are typically used. In recent times polymer modification of some of these binders has seen increased use. Different mix design procedures can result in the selection of different binder types as well as different binder contents. This aspect of the cold recycling process has led many states to develop their own design philosophies and procedures. These efforts are generally based on considerable local field performance data.
In addition to the more traditional methods of producing cold in-place material where the binder is incorporated directly into the salvaged material and then mixed together, foamed asphalt has seen a renewed interest and use. Foamed asphalt is a technique where the asphalt is foamed by first combining hot asphalt binder with water. The foamed binder is then mixed with the salvaged material by methods similar to those used in other cold recycling methods.
Although Arizona was one of the first states to use foamed asphalt techniques in the early 1960s, it has seen little or no use since that time. With advances in foaming procedures and mix design techniques, this may be a very cost-effective strategy.
Although the Arizona Dept of Transportation (ADOT) has constructed several cold in-place recycled projects, only limited or no experience exists with some of the different binder types and construction techniques. Since cold in-place recycling potentially offers considerable economic advantages, additional research is necessary to establish the best techniques and binders for use in construction and to begin to establish the life cycle costs of these design strategies.
The objective of this research is to evaluate the performance of test sections constructed using selected binder types and construction procedures. The test sections will be constructed to establish long term pavement performance.
At a minimum, the following tasks will be accomplished:
After three to five years of performance data, it is expected that the cost-effective design strategies and techniques will be incorporated into the pavement design process for strategy selection.
Eight test sections were constructed on SR87 north of Holbrook. Plans are underway to saw beam specimens from the roadway and test them in fatigue for materials characterization. All the test sections are performing similarly to date. A review of the historical information available for all of ADOTs approximate 20 CIR projects was conducted by ARA to document their construction and to evaluate their performance. A draft final report has been submitted.

Arizona is a mountainous state and many miles of the highway network pass through steep terrain, where rock slopes are adjacent to the highway. Rock falls of various dimensions occur and can cause damage to property and result in injury to people. The Arizona Department of Transportation (ADOT) has the responsibility to reduce the risks caused by these rock falls.
The objective of this research is to develop a non-invasive, low-cost rock slope stabilizing technique
The results of this research will provide Shotcrete materials and placement techniques that will enable contractor and maintenance personnel to non-invasively stabilize rock masses. Another product of the research will be a rock slope evaluation procedure to be used to determine where these materials/techniques will be used effectively. This information will be provided in easily understood material along with some training information.
Two interim reports were submitted and reviewed by the technical advisory committee, the first in July 1999 and the second in July 2001. Those two phases of the project are now completed. The second phase included a 2-year observation of stabilized rock masses for which no failures were observed. During the same observation period, 400 rock falls were recorded from adjacent non-stabilized rock, an affirmation of selective stabilization.
A final phase of this project was requested, and tentatively approved, to resolve the issue of performance in severe freeze-thaw areas - to be performed on US60 MP 236. This final phase, for a budget of $36,500, will also investigate the use of site mixed concrete and fluid enhancing techniques.

The continued preservation of the Arizona Department of Transportations (ADOT) pavements becomes an ever-increasing issue as non-renewable resources such as mineral aggregate become more and more difficult to obtain. Historically, ADOTs design philosophies have resulted in strategies that consist primarily of mill and fill and overlay. These pavement strategies are designed for approximately a ten-year life, at which time, another similar treatment would be performed.
Proper design philosophies evaluate life cycle costs to select the best available design option. However, the life cycle cost consists of both the construction cost and the user cost incurred by the public through delay, etc. While construction costs are easily defined, user costs are very difficult to quantify and often times may actually exceed the actual cost of the facility being constructed. Since the user costs are not directly borne by the agency, it becomes somewhat of a philosophical discussion as to what user costs should be considered.
In recent times, mineral aggregate sources have become increasingly more difficult to obtain in Arizona. However, our current design philosophies and economics require needing new materials approximately every ten years.
There is a need to consider reconstruction of significant roadways so that they can obtain design lives, perhaps as many as thirty to forty years before rehabilitation or reconstruction.
The objective of this research is to evaluate the best pavement design strategies available, considering the recently completed research project on pavement performance and the recently developed life cycle cost analysis model prepared by the Federal Highway Administration (FHWA).
The minimum following tasks will be performed:
The results from this study would be used by the pavement design group for selecting cost-effective design strategies.
The project is essentially complete. A draft final report has been submitted and is awaiting review by the TAC.

The use of warranty specifications has long been a consideration of the innovative contracting techniques. This type of specification was first used in Arizona for landscape items. However, there has been little use of this application in the Arizona Dept of Transportations (ADOT) highway construction other than for landscaping. Historically, the Federal Highway Administration (FHWA) would not allow warranties on Federal Aid Construction. There is also a continued belief that if you develop proper specifications, use quality materials and inspection techniques, there should not be a need for warranties.
However, there appears to be a growing need for maintenance activities on newly constructed roadway projects. This is a result of some aspect of the construction feature not performing as intended. This could be the result of improper design or improper construction. In either event, it requires additional, unplanned expenditure of resources.
The use of warranty specifications reduces the resources necessary to provide the initial inspection as well as the maintenance resources necessary to make repairs soon after construction. Recent discussions regarding contractor placed chip seals suggests that they may not be performing as expected. The use of warranties may improve their performance for example.
The objective of this research is to evaluate the institutional, political, and legal issues surrounding the implementation of warranty periods for construction projects.
The minimum following tasks will be accomplished:
The product of this research will be an implementation plan that provides the information and procedures necessary for including warranties in Arizona highway construction projects.
Two warranty projects have been developed. The first, which used a two-year warranty, has been successfully completed. The second warranty project was to be constructed during the fall of 02 and spring of 03. The construction project was terminated due to the condition of the existing pavement. The specifications, test procedures, and performance requirements have been developed for ADOT implementation. This work is being conducted in-house.

The planning and development of a single construction project involves many tasks and different agencies as well as a significant number of internal Arizona Department of Transportation (ADOT) organizations and individuals. This requires that all projects be scoped and planned well in advance so that right-of-way (R/W) and environmental clearance can be obtained and that sufficient time is available to test and design the facilities.
However, it often times takes as long as six to eight years from when the need for a particular project is first identified to when actual construction is underway. During this time, the infrastructure asset can deteriorate significantly and/or the problem being solved by the new project can become critical. There is a need to reduce the cycle time from when the need for a project is first identified until it is under construction. This will significantly improve our ability to respond to ever changing conditions and provide higher levels of service to our customers.
The objective of this project is to identify the changes necessary to reduce cycle time in getting construction projects underway and to develop an implementation plan to accomplish these changes.
The minimum following tasks will be performed:
No implementation is currently expected.

Traditionally, mix designs for gap-graded asphalt-rubber asphalt concrete (AR-AC) have been performed by the Arizona Department of Transportation (ADOT) staff using experience and judgment. Test criteria and specifications have not evolved to the point that mix design activities can be out-sourced. This results in significant reliance on personal judgment and experience. This also prevents standardization and proper performance evaluation.
ADOT currently uses recipe or method type specifications for AR-AC construction. The method specifications have evolved with time and represent the collective experience and knowledge of the agency. However, this experience is difficult to transfer and improve.
In the early 1990s, the Federal Highway Administration (FHWA) formed a pooled fund study to develop mix design procedures and specifications for asphalt-rubber asphalt concrete mixtures. Unfortunately, prior to completion, this study was terminated without producing these products. There is a need to standardize mix design procedures for AR-AC. This will allow outsourcing of the mix designs, standardization of the procedures, more contractor responsibility in achieving a quality product, and better performance measurements.
The objective of this research is to develop mix design procedures for designing and specifying AR-AC mixtures in construction.
The minimum following tasks will be performed:

The new AASTHO 2002 Pavement Design Guide will use a mechanistic-empirical design procedure. This is a completely new form of pavement design compared to previous AASHTO design procedures. Use of this type of approach requires knowledge regarding the modulus, thickness, and poisons ratio of each layer. Unfortunately, the current construction specifications are not based on these engineering properties. To successfully implement any mechanistic pavement design procedure and to move towards performance-related specifications, it is essential to develop tools that can measure the modulus of each layer. There is a need evaluate tools that measure modulus and can be combined with results from laboratory and field tests and quality control during construction. To attain a goal of performance related specifications it will be necessary to unify design methodologies to the construction quality control. Currently there is seismic based equipment that can be readily used in the laboratory for determining the modulus during the mix design stage and then used in the field to measure the as-constructed pavement modulus. These tests can be performed in two to three minutes and are completely non-destructive. They do not requiring coring of the materials nor any special fabrication in the lab beyond what is normally done during the design procedure.
The research objective is to develop a pilot program similar to what the Texas DOT is doing for evaluating the use of seismic equipment for construction quality control of hot mix asphalt concrete pavements.
If successful, implementation would require purchasing equipment

The durability of concrete aggregate has long been a problem in the transportation community. In particular, Alkali-Silica Reactivity (ASR) and Sulfate attack have been the two predominant problems associated with long-term concrete durability. Although considered an issue in surrounding states, this has not been considered a serious problem for structures or bridges in Arizona. Unfortunately, these problems typically take many years to manifest themselves and once detected, corrective action is often times difficult to undertake. So prevention is the best solution.
ASR and sulfate attack, although different distress mechanisms, occur as a result of an interaction between the environment and the concrete. Both distresses cause expansion within the hardened concrete resulting in cracking of the concrete.
A recent study on a major airfield in Arizona determined that significant alkali-silica reaction had occurred in the 14-year old concrete pavement. This suggests that this may be more of a concern than previously believed. This, coupled with the fact that it is an issue in surrounding states with similar geological sources, suggests that this needs further research.
The objective of this research would be to review the available knowledge regarding aggregate problems in Arizona and the surrounding states. The minimum following tasks would be performed:
The product of this effort would be a report detailing the available information on aggregate performance in Arizona and surrounding states.

Historically, noise mitigation measures used in the U.S. transportation industry have included use of barriers, walls, and separation (e.g., distance). These methods have been the only acceptable solutions for federally funded projects. Quiet pavements can also be used to mitigate noise but are not currently permitted because the Federal Highway Administration (FHWA) does not view them as a permanent solution.
In Arizona, like other states, berms and walls are the primary noise mitigation measures in the urban corridors. In April 2003, ADOT received approval from FHWA to allow the use of pavement surface type as a noise mitigation strategy. This approval allowed the use of Asphalt Rubber Friction Course (ARFC) overlays as a noise mitigation strategy when used on existing and newly constructed concrete pavements. Where this surfacing is used, ADOT receives a four-decibel reduction for the design of walls and berms. This credit equates to a six to eight foot reduction in wall or barrier height. Perhaps a more meaningful analogy is that if just a three-decibel reduction were achieved through the use of a quiet pavement, it would have a noise impact of about half of the actual traffic volume.
The FHWA approval was granted with the condition that Arizona be a pilot program, with specific research objectives and requirements. The required research is intended to validate the efficacy of using ARFC as a noise mitigation strategy. Since the FHWA was concerned that a pavement solution is not a permanent solution, they requested a pilot program to study the long-term performance of the ARFC overlay. ADOT committed to a long-range study for up to 10 years, the estimated minimum life cycle of the ARFC pavement.
The ADOT Intermodal Transportation Division (ITD) is currently conducting studies of Type 2 (wayside noise measurement) sites. The ITD studies will complement this research which focuses on Type 1 (source noise) and Type 3 (research grade) sites.
The objective of the research is to measure and compare noise generated from different pavement types over time. The effects of pavement design and pavement age will be monitored as they affect noise generation from vehicle traffic.
The results of the research will be used in the design of future road construction projects.

Currently, ADOT accepts asphalt concrete production based on ten different quality factors. These include: sand equivalent, fractured coarse aggregate particles, uncompacted void content (special mix), material spread, gradation, asphalt cement content, effective voids, stability, compaction, and smoothness.
Of these ten, four are used to determine the mixture-properties and compaction pay factor. They are gradation, asphalt cement content, effective voids, and compaction. The mixture property and compaction pay factor is used to pay the contractor for each ton of asphalt produced on the project. The purpose of the mixture pay factor is to determine payment, based upon on the percent of product within a specified tolerance. This allows payment to be based upon mixture quality. That is, the higher the quality the higher resulting payment.
The mixture property and compaction pay factors were largely developed on experience and judgment and on production equipment capability. The linkage between these pay factors and pavement performance and pavement design is currently not known.
It would be very beneficial to have pay factors that are based upon actual pavement performance and design procedures. The recently completed NCHRP 2002 Pavement Analysis tool provides the capability to evaluate the effect of these mixture characteristics on pavement design and performance. Therefore, rational pay factors could be determined based upon actual design conditions and attendant pavement performance.
The objective of this research is to develop new pay factors for inclusion into ADOTs specifications based upon analysis conducted using the NCHRP 2002 Pavement Analysis Tool. Sensitivity analysis will be conducted for each of the relevant mixture and compaction properties to determine their effect on pavement performance.
The results of this research should be used to replace the pay factors shown in section 416 of the standard specifications.

The Arizona Department of Transportation (ADOT) has primary responsibility for enforcing laws regulating size and weight of commercial and non-commercial vehicles on the states highways. ADOTs Motor Vehicle Division (MVD) coordinates enforcement activities. It is contended that overweight vehicles are the primary cause of highways within this state failing to meet their expected or designed life spans. Overweight vehicle axles cause a damage factor to the fourth power to pavement and the infrastructure. This equates to millions of dollars in damage that must be funded from highway user taxes and other sources. These expenditures for avoidable maintenance reduce the capability and funding to build new highways and to maintain existing roads in a comprehensive manner. We need to identify and quantify that cost figure.
The proposed research would promote effective enforcement of size and weight laws on Arizona highways. It would also give evidence of overspending or under spending for this activity. This would give valuable information to support efforts in weight enforcement, make planning for future highways more efficient, and provide budgetary directions or priorities for MVD.

Public transportation is rarely available in rural regions of Arizona. This puts those unable to drive themselves at a serious disadvantage when it comes to mobility.
Government entities in rural regions may lack information on how to start and operate a public transit system appropriate for their area. Getting this information could be the critical input needed to initiate more rural transit options in Arizona.
Identify, prioritize and discuss the most critical factors for the implementation of new general public transit systems in rural Arizona. Examples of factors could include local leadership, state and federal funding, transit dependency characteristics of local population, urban form and trip attractions.
The research will result in information that could be used to guide a more effective rural transit program in Arizona. The Transportation Planning Division will be the process owner.

The Arizona Department of Transportation (ADOT) wishes to do more electronic transactions (electronic bidding, procurement, other Motor Vehicle Division transactions, etc.). Many of these transactions require a signature in order to prove a particular person signed a document. Without an electronic means to prove that a particular person or business approved the transaction, these electronic transactions are not possible. This adversely affects the Arizona Department of Transportation by precluding these transactions from being done electronically.
Electronic commerce relies on secure communication between two or more trusting parties. Digital signatures are a necessary component for electronically completing certain transactions. With the volume of electronic commerce and business-to-business transactions skyrocketing, the acceptance of digital signatures is more a question of when rather than if.
But what exactly will a digital signature look like? While most people might imagine scribbling with little electronic pens on an interactive notepad, digital signatures will, for the foreseeable future, remain far more arcane and not entirely intuitive. For now, a signature is likely to be a simple bit of encryption embedded in ones own personal computer that tells other computers that a request for a commercial transaction over the Internet is coming from ones computer.
Digital signatures ensure a higher level of security and privacy for electronic messages or transactions. Using encryption algorithms, the sender encodes and then "signs" his message, and the receiver can only decode and read it with a corresponding secret code, or "key." The signature lets the receiver know the message hasn't been tampered with or forged. Many observers feel that adoption of such schemes, coupled with strong encryption, is necessary for mass use of the Internet for electronic commerce.
The estimated implementation cost for a full deployment will be determined by the research project. The Information Technology Group will be the ultimate process owner.

Various federal and state motor carrier safety information systems are now available, but are not installed nor being used at the Nogales Cargo Port. This hampers the ability for all commercial vehicle safety inspectors to capture, communicate and collect data pertinent to vehicles and drivers they are examining. The inability of truck inspectors to have immediate access to required records may lead to potential accidents or allow problem drivers to operate vehicles.
The state and federal governments are developing a multi-million dollar inspection facility at Nogales. The lack of timely vehicle and driver information will have an impact on the facility operating at full potential.
A Commercial Vehicle Information Systems Network (CVISN) will provide Arizona and federal truck inspectors with an excellent means to use available technology to obtain and exchange driver and vehicle records, both with Mexican and US authorities, especially as they relate to Motor Carrier Safety and crash history. A Commercial Vehicle Information Systems Network is another smart technology enhancement that will make easier law enforcement's job of making highways safer for the motoring public and preserving the transportation infrastructure.
Evaluate the specific needs in terms of a safety information exchange system under the umbrella of a Commercial Vehicle Information Systems Network and intelligent transportation systems related technologies.
The research outcome will help identify how the Arizona Department of Transportation, along with the Department of Public Safety and U.S. Department of Transportation, can enhance their collective motor carrier safety objectives. These successful accomplishments will lead to safer vehicles, safer drivers and an overall safer highway transportation environment, with an attendant drop in highway crashes and a decrease in resultant injuries and fatalities. The Motor Vehicle Division of the Arizona Department of Transportation will be the process owner.

Registering a vehicle and obtaining a drivers license are among the major points of contact between the public and the Arizona Department of Transportation (ADOT). We want to be customer friendly and make these types of transactions as simple as possible. At the same time, ADOT must ensure that drivers are qualified and fees are paid.
To minimize cost and maximize customer satisfaction, transactions between customers and ADOT should be conducted as efficiently as possible. Some of these transactions can be conducted over the phone, by mail, or on the internet. Other transactions (new drivers licenses, for example) require that the customer come to a Motor Vehicle Division (MVD) field office to take a vision or on-the-road test. There are an array of options and strategies for conducting these various transactions.
The question is, which set of options or strategies would be optimal for meeting the needs of ADOT and its customers?
1. Compile a comprehensive list of transaction methods that might be used by the Motor Vehicle Division.
2. Describe the advantages and disadvantages of each method.
3. Where feasible, estimate a cost/benefit profile for each method.
The research will result in information that could be used to guide a more effective Motor Vehicle Division customer service program in Arizona. MVD will be the process owner.

Driver education is widely used as a preventive and remedial measure aimed at improving roadway safety. A variety of programs are offered in Arizona and other states by government and private entities. The Governors Traffic Safety Advisory Council (GTSAC) is interested in examining the effectiveness of these programs and whether Arizona ought to invest more funds and efforts in driver education programs and, if so, which programs offer the best return on investment.
What is needed is a comprehensive survey of the results of these driver education programs in terms of before-and-after traffic crash and traffic violation rates (especially repeat offenders) for areas that use these various driver education programs vs. areas that do not. This survey should include programs within Arizona, as well as programs in other states. This would give state and local governments in Arizona a sound foundation for investing funds in ways that would efficiently improve roadway safety.
1. Estimate the impact of driver education programs on traffic crash and violation rates.
2. Estimate a cost/benefit profile for these programs where feasible.

In June 2001, the Arizona Transportation Research Center (ATRC) completed a research project in which a model was developed for evaluating prospective safety projects on local government streets and roadways. This model enables the user to identify high crash locations based on total crashes, fatalities, and aggregate cost of crashes. Further, the model then permits the user to compare benefit/cost ratios for prospective safety improvements. The result is a tool that assists local governments in selecting the most cost-effective means for remedying the worst crash locations.
This proposed project would adapt the previously developed model to include State Highways in the database. This would enable a more comprehensive safety analysis of all roadways in Arizona. Users of the model would be able to identify and propose remedies for the worst crash sites regardless of the jurisdiction controlling the sites. Safety project investments could be optimized across jurisdictional boundaries and drivers in Arizona would enjoy the maximum pay-off in terms of reduced crash costs per dollar of investment no matter where they travel in the state.
1. The existing database model will be enhanced to accommodate a statewide, multi-jurisdictional perspective.
The research will result in a report and model that can be used by state and local governments to more effectively evaluate potential safety projects. The process owner would be the Transportation Planning Division, ADOT.

Red light cameras and photo-radar are widely used automated traffic law enforcement devices. Would expanding their use even further be a cost-effective way to increase roadway safety? Or are there other more simple and less costly ways of reducing crashes? For example, it has been suggested that increasing the yellow-phase on traffic signals would be an effective way to reduce red-light crashes.
What is needed is a comprehensive survey of results as measured by before-and-after traffic crash rates for areas that use these devices vs. areas that do not. One or more other simple measures for decreasing crash rates will be examined for comparative purposes. Such research would give state and local governments a sound foundation for investing funds in ways that would efficiently improve roadway safety.
1. Estimate the impact of red-light cameras and photo-radar on traffic crash rates.
2. Compare these estimates with one or more simpler alternative measures.

The Arizona Driver License Manual is the states main tool for instructing drivers in the rules of the road. The Manual represents one of the Departments greatest opportunities/responsibilities for motoring public safety education. A good manual has the potential to make better drivers. Since the driver is the most significant factor in roadway safety, it is incumbent upon states to make their driver manuals as good as they can be.
Arizonas driver license manual is reviewed and updated annually by the Motor Vehicle Division (MVD), but this mainly addresses legislative and business process changes. A benchmarking effort that is both thorough and comprehensive to validate or enhance the content, formatting and delivery method of the information contained in the manual is needed.
1. Determine the best practices in driver manual publication and dissemination.
2. Recommend steps necessary for Arizona to adopt the best practices.
3. Document the safety implications of having a good driver manual.
The research will help determine if improvements to the Arizona Drivers Manual should be made. The Motor Vehicle Division will be the process owner.

With the advent of an aging population in Arizona, the need for a Comprehensive Automated Vision Testing program is increasing. The current process within the Motor Vehicle Division (MVD) is lacking in identifying vision deficient drivers. The increased traffic volumes present multiple challenges to all Drivers, but especially those with a vision deficiency. The lack of a Glare Recovery component, a Depth Perception Component and a good Peripheral Vision Component, leaves many Arizona drivers unprepared for the challenges of driving. Vision is 80% of the driving task, it is imperative that Arizona investigate new technology in this Area. With the expanded time frames between required re-testing, compounds the need for a better Screening process. Sign recognition, traffic signal identification, increasing traffic volumes and Traffic congestion all play an important part in the driving process. A vision deficient driver may be operating under the assumption that they are OK, because they have an Arizona Drivers License.
1. Identify cutting edge technology in the area.
2. Propose improved / new technology for testing.
3. Test and evaluate new technology.
4. Prepare and publish report of evaluation.
The Arizona Department of Transportation (ADOT) will conduct the research in two phases: (1) a pre-installation review of options and (2) a post-installation test of the chosen option. MVD will carry out the ultimate implementation if the recommendation of the research calls for it.
The estimated implementation cost for a full deployment will be determined by the research project. MVD will be the ultimate process owner.
The project is nearing completion.

Determine the extent and impact of commercial vehicles that bypass or circumvent the ports of entry (port runners) in order to avoid purchasing the appropriate permits or being cited for non-compliance with weight and/or registration requirements on roadways and revenues. It is widely believed that port runners are often illegal, carrying cargo that exceeds their limits, or drive in excess of the limits set by statute. This affects Arizona highways due to the increased damage incurred by overweight vehicles, decreases the safety of the motoring public due to potentially unsafe vehicles or drivers reduced capacity. Without clear knowledge of the extent of this problem, we cannot properly staff the facilities to impact this activity, nor divert resources to the locations and times most prevalent for these violators.
The Arizona Transportation Research Center (ATRC) will contract with a consultant to conduct the research. Arizona Department of Transportation (ADOT) management will determine whether to advocate any changes in existing law. If legislation is needed, ADOT will work with the governor and legislature to draft appropriate new laws.
The research will result in information that could help promote a more effective port monitoring of trucking in Arizona. With this information, more effective investment of public funds in highway transportation will be possible. ADOTs Motor Vehicle Division (MVD) will be the process owner. ADOT management will decide whether to implement any operational changes.

The Arizona Department of Transportations (ADOTs) approach to managing its highway maintenance program is based on developing the methodology and establishing maintenance processes, tools, and systems to achieve predefined Levels-of-Service (LOS) that are derived from customer input. This concept shifts emphasis from the traditional work program outputs to using maintenance programs to accomplish the desired LOS. It introduces accountability to the budgeting and allocation of maintenance funds by trying to tie dollars directly to LOS, as expressed by the using public. However, the program lacks the important ability to accurately predict the change in level-of-service measurements of features or feature groups when there is a change in the statewide maintenance budget or in the amount spent on a feature or feature group. Also, these LOS ratings or measurements are required to be reported to the Joint Legislative Budget Committee (JLBC) each year. For fiscal year (FY) 2004 the JLBC requires that we report all the LOS ratings in our strategic plan as only one composite number that combines the ratings from all features statewide.
The Arizona Transportation Research Center (ATRC) will contract with a consultant to conduct the research. ADOT central maintenance will assist in providing necessary cost data and level-of-service measurements from the maintenance management system.
The research will allow the Intermodal Transportation Division (ITD) to better allocate scarce maintenance funding to more efficiently maintain and operate the state highway system. It will also allow a better prediction of the impact on the system from a proposed increase or decrease in the budget. The state engineers office will be the process owner.

Visitors to Grand Canyon National Park (GCNP), Arizonas premier attraction, average approximately 4.5m/year. Motor vehicles are the main travel mode for the vast majority of park visitors (car, rental, recreational vehicle (RV), tour bus, etc.); thus GCNP visitors have an enormous impact on highways and transportation corridors throughout Arizona, especially northern Arizona. Yet, the exact nature of this impact is not known. A scientific survey, conducted over a full-year to account for seasonal variations, has not been conducted since 1983. The Arizona Hospitality Research and Resource Center (AHRRC) at Northern Arizona University has proposed, in conjunction with the National Park Service, to conduct a thorough survey of GCNP visitors. This research will produce data on highway usage and visitors travel patterns, including: travel mode (auto, rental, RV, tour bus, air, etc.); state-entry points and park-entrance roads used; overall trip miles; roads traveled and communities visited; perceptions (quality/satisfaction) of northern Arizona roadways; perceptions of highway safety & congestion; availability of traveler amenities/rest stops; other areas in consultation with the Arizona Department of Transportation (ADOT).
Transportation problems are not new to GCNP; automobile congestion inside the park is critical, auto congestion on SR 64, 180 & 89 is problematic. Also, state-owned GCNP airport is a key player in the park transport system and visitor experience mainly carrying out-of-state (Las Vegas) & foreign visitors. Visitors transportation data are critical to ADOT decision-makers for planning decisions concerning major roadways (SR64, 180 and 89 and GCNP airport), and road logistics (procurement, maintenance, etc.). Traffic counts do not tell the whole story of current highway usage or help assess future needs.
Increase knowledge of GCNP visitors travel patterns, road usage quantitative & qualitative.
The Arizona Transportation Research Center (ATRC) will conduct the research in partnership with NAU and with permission of the National Park Service. ADOT management will determine how the research output will be integrated into the states planning activities.
This research helps to develop transportation strategies to improve the overall efficiency of the transportation system, reduce environmental impacts, plan infrastructure investments, efficient access, and development patterns. Information is essential to inform decision-makers at all levels federal, state and local on issues regarding visitor travel patterns on Arizona roadways, as well as overall use and allocation of TEA-21 funds, with special attention to national park and tourism/visitor usage. The process owner would be the Transportation Planning Division of ADOT.

Arizona Highways Magazine, part of the Arizona Department of Transportation (ADOT), is a world-renowned travel publication. Anecdotal data from the Arizona Office of Tourism coupled with data from subscriber research suggests the magazine is annually responsible for over $300 million in tourist revenue (not counting direct revenue from subscribers and sales of related products such as calendars, books and general merchandise).
We need to be able to more formally quantify this number in order to better understand the dynamics between the magazine, its related products revenue and tourism revenue. This will help maximize the magazines impact on boosting tourist revenue for the state of Arizona and build the case for using some of this revenue for highway improvements.
1. Quantify and document the link between Arizona Highways magazine and tourist traffic and revenue.
2. Ascertain the implications for highway facility needs and revenue generation.
The Arizona Transportation Research Center (ATRC) will conduct the research with the assistance of one or more university graduate students. Arizona Highways publisher will determine how to modify processes at the magazine to best implement the research findings.
The research will result in information that could be used to guide a more effective use of Arizona Highways magazine to stimulate tourism and tourist revenue generation in Arizona. Arizona Highways magazine will be the process owner.

The IRS and the State of Arizona allow diesel used for farm, construction, or other off-road use to be purchased tax-free. This tax-free diesel must be dyed red to identify it as off-road diesel and fuel suppliers must report their sales of dyed diesel on a monthly basis. Because about one-third of the retail price of diesel is tax, there is motivation to inappropriately use dyed diesel in on-road vehicles. The on-road use of dyed diesel deprives the State of highway tax revenue and in August, 2002, ADOT initiated federally funded education and enforcement efforts to decrease inappropriate (i.e., on-road) use of dyed diesel.
The current education and enforcement efforts are resulting in the collection of taxes and penalties, but the ultimate program goal of decreasing the on-road use of dyed diesel cannot currently be evaluated. Currently there are no indicators of what impact the education and enforcement program has on on-road dyed diesel use. The needed indicators can be developed from an analysis of ADOT fuel supplier report data. In addition, ADOT counterparts at the IRS engage in similar education and enforcement efforts. The IRS has agreed to provide access to their fuel supplier data in support of this evaluation. The collaborative nature of this project will result in the creation of robust program effectiveness measures.
1. Identify valid measures of effectiveness for dyed diesel education and enforcement efforts.
2. Evaluate the effectiveness of the dyed diesel education and enforcement efforts.
3. Identify opportunities for improving the effectiveness of education and enforcement efforts.
4. Identify strategies for improving the effectiveness of education and enforcement efforts.
The Arizona Transportation Research Center (ATRC) will conduct the research with the assistance of one or more university graduate students. ADOT management will determine which improvement strategies to pursue.
The research will result in knowledge that will allow ADOT to evaluate and improve dyed diesel education and enforcement efforts. ADOT MVD will be the process owner.

The current annual inventory process relies completely on personnel and handwritten documentation. Human error and a lengthy documenting process is not cost effective or time productive. With this process relying on written tracking method multiple items that are listed as lost are usually located in another office, sent to surplus or in storage.
ADOT needs to research the availability of a bar code tag printer, hand held scanners and a software program to accommodate the information. This program could track items as they are received, sent to surplus, storage throughout the year instead of annually.
1. Assess barcode technology and its cost-effectiveness for conducting ADOT inventories.
2. Install a barcode system as a pilot project and collect data on its effectiveness.
3. Determine whether barcode technology should be implemented organization-wide in appropriate settings.
ATRC will conduct the research in two phases. One phase will consist of pre-installation analysis of options. The other will consist of equipment acquisition and installation and evaluation of results.
The research will provide data that could be used to achieve more effective inventory measurements/audits. The ADOT Process owner would be Fixed Assets section of ADOT.

Drilled shaft foundations support a significant portion of the bridge substructures in Arizona. These drilled shafts are commonly supported in mixed soils types known as sand-gravel-cobbles (SGC) layer and derive their capacities from side friction and end bearing in SGC layer. Current design procedures and parameters are based on uniform soil conditions. Soils medium is modeled either as clay or sand. Limited amounts of research data are available for design of drilled shafts supported in granular soils with significant gravel and cobble contents. Current American Association of State Highway and Transportation Officials (AASHTO) design method for drilled shafts in granular soils medium is based on the equations proposed by Reese and ONeil (Federal Highway Administration (FHWA) Procedure). Meyerhoff and Kulhawy developed the other two common design procedures. Available load test data indicate that measured drilled shaft capacities tend to be larger with an increase in gravel content of the granular soils than the design capacities. Additionally, the capacity tends to increase with the increase of calcium carbonate cementation. However, definitive relationships among these variables and corresponding design parameters are not available for general design applications. Drilled shafts in mixed soils (i.e., SGC) conditions will support significant number of bridge foundations in the future. Significant savings could be realized if design parameters and procedures could be developed to account for the increase in friction of soils with the increase of gravel content and calcium carbonate cementation.
The following tasks will be performed:
The research has resulted in an evaluation of the current AASHTO design method for drilled shaft foundations based on the available load test data on drilled shafts in SGC soils. The research has provided information to be used to improve the design of drilled shaft foundations for bridges and structures.
The research has been basically completed during the past year. Research work was on hold while a separate effort to initiate a related Federal Pooled Fund project was monitored. The completed final draft report has been submitted to ATRC for review before publication.

Each year numerous bridge deck joints must be replaced and/or repaired in the Arizona State Highway System Inventory. Certain types of bridge deck joints have failed prematurely or required extensive repairs within a very short time after installation. This is due in part, but not limited to, poor design, poor quality materials, improper engineering, faulty installation, and poor concrete quality. This has become a great concern in maintaining the state highway system, not to mention the enormous cost of replacing and/or repairing bridge deck joints. This also causes great inconvenience to the motoring public due to traffic control and closures required on an already congested highway system.
Although considerable research has been conducted in this area, most of the work deals with bridges built in other climates. The desert Southwest imposes some unique performance requirements. The area is arid, experiences large daily temperature changes, and high ultraviolet exposure. The northern portion of the state is also subjected to cold temperatures, and ice and snow control (salt and cinders) measures. The performance of bridge deck joint seals in Arizona has been evaluated and joint seal designs developed for the unique Arizona conditions. The initial research has discovered that the primary cause for bridge deck problems is in the various initial installation steps. The research is developing tools for construction and inspection to assure the deck joints are properly installed. A video is being prepared for use by construction inspectors, as their turnover rate is high.
Investigate the design, performance, durability, cost effectiveness, constructibility, and maintenance of existing bridge deck joints on the Arizona State Highway System.
Summarize the findings for existing bridge deck joints, with special attention paid to types of failures and the reasons for them.
In addition to existing types, analyze other alternative bridge deck joints available on the market in light of existing problems. Specifically look at the role the Southwests climate plays in the design, performance, durability, cost effectiveness, constructibility, and maintenance of bridge deck joints.
The following tasks will be performed:
The research will result in ADOT Bridge Group being able to immediately implement the recommended types of bridge deck joints, procedures and recommendations for various applications on ongoing and for future projects statewide.
Engineering Consultant selected. Project about 35% completed. Literature research completed. Bridge Deck life cycle analysis completed. Research will be completed focusing on installation aides, procedures and specification recommendations.

In order to stimulate the use of higher quality concrete in highway structures, the Federal Highway Administration has strongly promoted high performance concrete (HPC) materials. High performance concrete has been found to be feasible in all aspects of concrete bridges including the decks, piers, and pre-stressed concrete girder cross-sections. Several studies have indicated that using concrete compressive strengths of up to 10,000 psi allowed longer span lengths and more economical structures. Many state agencies have thus saved construction time and money by using high performance concrete. One of the reasons why HPC is not regularly specified for highway structures in Arizona may be the lack of available data regarding the field use in hot and arid climates. This proposal will seek to develop and implement the use of high performance concrete in Arizona's bridges.
The objectives of this research project are to evaluate the applicability of using high performance concrete in structures in Arizona and to determine any climate-related issues associated with the use of high performance concrete.
The researcher will accomplish the following tasks:
This project will increase the acceptability of high performance concrete materials in the local community. It will help address some of the process, parameters, and design challenges faced by the bridge group in designing cost-effective, compact, and strong structures through the use of higher strength materials. By reducing extra piers and members, it may reduce the size requirements of many new and rehabilitated structures. The research results will be tested in specific bridge design project.

Corrosion in reinforcing steel and the lack of concrete durability are two of the most severe deterioration problems for bridges today. Arizona has experienced both of these problems. Today, the increasing use of de-icing chemicals has been accompanied by the need for increasing attention to bridge deck maintenance and repair work. Currently, the Arizona Department of Transportation (ADOT) has 31 bridges on Interstate and State Routes requiring some kind of bridge deck rehabilitation. The cost to rehabilitate these bridge decks becomes very expensive due to the traffic controls and the adopted retrofit methods. In addition, more bridge decks need to be rehabilitated due to their aging and de-icing chemical usage. The current budget for deck repair is not adequate and ADOT needs to establish a cost-effective program to repair these deteriorated bridge decks in a systematic way with current up-to-date technologies available. A research project needs to be established to study the following topics: (1) protective strategies to minimize the deck deterioration problems and (2) cost effective retrofit schemes to rehabilitate deteriorated bridge decks.
The objectives of this research project are to develop: protective strategies to minimize bridge deck deterioration and cost-effective retrofit schemes to rehabilitate deteriorated bridge decks.
Research Tasks
Effective protective strategies to minimize bridge deck deterioration, and cost-effective retrofit schemes to rehabilitate deteriorated bridge decks will be incorporated into ADOT practice and manuals. One bridge project rehab will be completed during the research period.

A number of significant research projects related to backfill material for retaining structures have been performed over the last decade. Cohesive soil, controlled low strength materials (CLSMs), recycled tire chip soil mix and more were studied for backfill material. But recycled asphaltic concrete and recycled crushed concrete have rarely been included in these studies. Recently contractors on several ADOT construction projects proposed using recycled concrete materials for structure backfill behind concrete cantilever retaining walls. Contractors have claimed that recycling existing concrete material from pavement removal in the vicinity of the project and using the material for the structure backfill behind the new retaining wall construction would be a significant cost saving idea. ADOT Geotechnical Design Section of Material Group and Bridge Design Sections of Bridge Group are very skeptical about this idea because of unavailability of data for design parameters for these materials unless extensive research is performed in this area. These design parameters consist of unit weight, internal frictional angle, shear strength, permeability and etc. Amount of moisture retained in the backfill material is directly related to permeability issue of backfill that will greatly affect the earth pressure acting on the wall. The finding of this investigation will provide the information to ADOT for evaluating the proposed materials sensibly and fairly. Acceptance of these materials is heavily dependent on the result of this research that will eventually link to the cost and quality of the future retaining wall construction.
Investigate earth pressure distribution on concrete cantilever retaining wall for (1) Structure Backfill meeting ADOTs current specifications (2) Recycled quality asphaltic concrete backfill mix (3) Recycled Quality Crushed Concrete backfill mix.
Research Tasks
The result from the research will provide the technical information to ADOT in order to evaluate the quality and value for using various proposed concrete backfill mixes that have been proposed by contractors.
This research has not yet begun.

State transportation agencies, such as the Arizona Department of Transportation (ADOT), are responsible for ensuring the safety and operational efficiency of state highways. Additionally, ADOT is mandated to collect and report accident information on an annual basis. This information is used by ADOT, county, and local jurisdictions to identify safety issues, plan counter-measures, and evaluate the effectiveness of safety-related improvements. While the goals are to provide a safe and efficient highway system, and to limit liability, staff and funding available for these purposes are limited.
Traditional analyses performed by state traffic and safety engineers to identify highway safety issues, to design and implement solutions, and to evaluate the results have been undertaken using largely manual methods in the past. Many analyses can now be automated using geographic information system technology to enhance their effectiveness and timeliness. These processes depend upon the availability of suitable accident records, traffic data, and other related data. Federal highway officials recommend and support developing more accurate, timely and complete highway safety data and traffic records systems. To help reduce highway deaths and injuries, federal officials have developed prototype tools around such data for various safety analyses: Strip, Spot/Intersection, Cluster, Sliding Scale, and Truck Corridor analysis.
Standard technological innovations, such as desktop- and Intranet/Internet-based geographic information systems (GIS) also offer robust and powerful platforms for identifying, analyzing, and disseminating accident information in the form of tabulations, reports, and maps. Research is needed to transform all of the accident, traffic and other data into knowledge so that better investment decisions can be made in regard to safety enhancements.
The objectives of this research project are to:
The following tasks will be performed:
This project would lead to safety research tools that leverage and enhance existing data at ADOT and may identify and develop other valuable data for use throughout the agency. It initiates the development of automated GIS-based tools for identifying high accident intersections and highway segments, investigating the accident rates, and evaluating subsequent improvements. The system could include automated density mapping, cluster analysis, correlations with other information (i.e. pavement width), statistical analysis, collision diagrams, maps, querying, and reporting. ADOT and other agencies could utilize the system for their own purposes. Implementation will be incorporated into this research project with additional funding to insure functionality of research findings.
The TAC has met and the Scope of work for the RFP has been developed. RFP has been advertised for consultant.

A preliminary comparison of accident records has been done for selected Single-Point Urban Interchanges (SPUIs) in the Phoenix metropolitan area. The results show that there have been a high number of accidents, and crashes of certain types, at the right turn yield locations of these TIs, compared to the signalized locations.
The SPUI sites reviewed initially were selected for their comparable high traffic volumes with little variation shown by day of the week. These sites include different control types for the right turn movements from the freeway off-ramps. At various SPUI locations around the Valley, there may be both one-lane designated right turns and two-lane designated right turns. Within these various locations, some of these turning movements are yield controlled and some are signal controlled. The impacts on capacity of these choices are also a concern.
If the preliminary data is correct, a higher level of safety or reduction in accidents may be possible for specific turning movements in these traffic interchanges, with the incorporation of different and/or more consistent modes of traffic control.
A thorough, more detailed study is indicated by these results, to compare the advantages of signal control vs. yield control at various applicable locations. This research effort, if done in a timely manner, could have a significant impact on traffic control decisions and on traffic safety at these and future related SPUI locations.
Preliminary analysis indicates that this is a serious safety issue. This project will perform a thorough and more detailed study, with a larger body of sample locations, comparing the safety performance and relative advantages of signal control vs. yield control at SPUIs.
The following tasks will be performed:
The results of this research will provide the Department with a higher understanding of what type of control to implement at future SPUI locations. A higher level of safety will be gained from the changes that may be recommended by this study. ADOTs Traffic Design, Traffic Operations and Maintenance sections will benefit from these results and from the definition of the changes to be made.
The benefits of this research would include:

Identification of high-risk crash sites is a difficult task that has received much attention in the literature. Because of the random fluctuation of crashes from year to year, a crash site may appear to represent a relatively high risk in a given year when in fact the sites underlying, inherent risk level is average or below.
Previous methods rely on simple ranking of crash rates, which is problematic since rates are not linear functions. This can produce false positive indications and may lead to fixing of safety problems at locations not requiring remediation. Corrections to this regression to the mean bias are often needed to account for the temporal fluctuation in crashes from year to year. Bayesian techniques, by accounting for both crash history and expected crashes for similar sites, have been shown to offer improved ability to identify high-risk sites.
Many DOTs face significant liabilities in regard to high-risk site identification and subsequent safety improvements. Because state-of-the-practice methods involve corrections for regression to the mean by Bayesian analysis, and since traditional ranking methods have been shown to do a poor job of identifying the truly high-risk sites, there is a significant need for this research.
This research project will focus on improving existing procedures for identifying high-risk crash sites in Arizona. By using the recently released Arizona Local Government Safety Project Analysis Model (Carey, 2001) as a starting point, the focus will be on improving the predictions and ranking of hazardous sites from this model.
Through this research, ADOT will obtain the following positive results:
The project has three primary objectives:
The following tasks will be performed:
This project is expected to provide tangible research results that may justify its long-term adoption by ADOT. It will demonstrate the benefits of state-of-the-practice Bayesian methodologies, as compared to the current analytical models, to more effectively identify high-risk sites for corrective safety measures.
The benefits to the State from this research would include:

Sharing freeway or state highway corridors with transit systems could have benefits related to transportation system planning and also cost savings. While aspects of this problem have been studied, a comprehensive compilation of current practices and research that would relate to Arizona is not available. This information would improve the States ability to develop cost effective transit solutions.
The research would develop strategies, which ADOT could implement for the multimodal optimization of urban freeway corridors that stimulate growth-induced demands for mobility. Roles of major participants in the development and funding of these strategies should be included.
The results of this research will assist transportation planners in developing long-term transit systems and likely save Arizona tax dollars by enabling the creation of lower cost transit systems.
The research will result in information that could be used to guide a more effective multi-modal program in Arizona.
The ADOT Public Transportation Division and the Communications and Community Partnerships Group will use the results of this research to facilitate their work related to transit planning.
This research will begin in January 2005.

Unsignalized intersections represent potential hazards not present at signalized intersections because of the priority of movement on the main road and significant speed difference as well as drivers' and pedestrians' perceptions. As a result, information such as traffic volume, highway geometric features and traffic control data is crucial to the crash analysis in addition to crash information. The current Arizona Department of Transportation (ADOT) program for identifying hazardous unsignalized intersections is challenged by the crash data limitation. For example, in some cases, one cannot tell from some crash records whether a crash occurred at a signalized-intersection or at an unsignalized intersection. The traditional analysis is further deteriorated by Regression-to-the-Mean (RTM) due to the random fluctuation of crash occurrence from year to year at a location. In other words, a short time period observation of a location may not provide a solid indication of the safety status of that location. The entire process is aggravated by the lack of staffing in terms of time and knowledge. Therefore, a systematic process is required to tackle all the aforementioned problems.
By streamlining the process, crash data can be combined with other data sources available at MAG and other jurisdictions to improve data coverage and data quality. The EB method can be adopted to overcome the RTM. Moreover, the GIS technologies can be incorporated into the process to save staff's time in data processing. For instance, routes and crashes can be overlaid with aerial photograph to provide the engineer with a better picture of the roadway configuration of a crash site. Various tools such as spot identification and corridor analysis will enhance the engineers ability to analyze unsignalized intersection safety problems at a project, corridor or even a network level.
Develop a GIS based screening process to systematically identify high crash risk at unsignalized intersections using Empirical Bayesian (EB) approach. The process is also instrumental in analyzing and addressing the crash causes which can potentially be utilized to support the future effort in implementing the AASHTO Highway Safety Plan.
The proposed project will make various types of supplemental information for crashes easily accessible to traffic engineers. More importantly, it could potentially avoid subjective judgment or bias in observation as a result of RTM and ensure the efficient and effective allocation of ADOT Hazard Eliminate Safety (HES) funds.
This research project will also identify the problem of the current system, compare the current system with alternative systems, and recommend further improvements and reducing construction costs. Our current databases do not contain the necessary data (i.e. approach geometrics, traffic control, volume) to do a systematic approach to improving safety at unsignalized intersections. Prepare to use safety funds from FHWA.
The ability to identify truly hazardous intersections is crucial for the safety of the Arizona transportation system and the agencies responsible for spending safety dollars. It is important that these locations can be identified through a systematic approach. A systematic process will enable the engineers to effectively propose safety projects that will have the greatest safety impact system wide and provide management with the necessary information that the worst locations are being addressed. It is anticipated that the results of this research can be assimilated in the development of other hazardous locations such as signalized intersections, roadway segments etc.
This research is beginning in November 2004.

Motor vehicle crashes (MVC) are a major cause of injuries and fatalities for American Indians traveling on state highways and other roads on reservations in Arizona. According to the Arizona Department of Health Services (ADHS), from 1990-2000 the average annual mortality rate from MVC per 100,000 population was 74.3 for American Indians compared to 19.4 for African Americans, 17.9 for White non-Hispanic, 20.1 for Hispanic and 13.5 for Asians. This trend continued in 2002; the MVC mortality rate was 68.6 compared to 20.4 per 100,000 population statewide.
The objectives of this project is to identify methods to assist Tribes to implement traffic safety infrastructure capacity in the areas of
1) Program Decision Making;
2.) Data Collection and Storage.
3) Equipment and Software;
4) Project Prioritization
5) Project Development, Implementation and Evaluation
Most Tribes do not have the staff, training or financial capacity to establish and maintain a safety program. This research will provide Tribes the guidance to develop the technical requirements needed to build this capacity. The benefits to the transportation system will be a reduction in the number of MVCs and associated deaths, injuries and property damage on reservations. Additionally creation of data collection systems will provide the state data network a vital missing elements of traffic safety statistics.
Implementation would reduce estimated economic loss from MVC fatalities for fifteen tribes which was from 1998-2002 $575,240,000 with a total of 565 lives lost. The research would also support the federal Reauthorization legislation which would increase safety funding for Arizona roads.
This project would assist Tribes abilities to access the FHWA national model for Tribes to compete for HES funds.
This project is just beginning FY 2005 and is anticipated to take up to 18 months.

Uniform databases do not currently exist for local jurisdictions to conduct detailed safety investment studies, which severely inhibits them from applying for statewide hazard elimination funds and ultimately reducing motor vehicle related deaths, injuries, and property damage.
The objective of this research is to assemble a regional crash database in the PAG metropolitan region compatible with the AZ LGPA Model that supports safety analysis efforts for MPO and COG member agencies, and enables these agencies to apply for hazard elimination funds. The research will provide a uniform regional platform for safety evaluation and data management by conducting the following tasks: 1) Assess local jurisdiction safety databases; 2) Prepare a status report; 3) Develop a Regional Databases Development Plan and Manual
Now is the time to develop a regional safety management database. Previous work by ADOT on the AZ LGPA Model and federal emphasis on safety conscious planning and consistent evaluation methodology provides a unique opportunity to implement a regional platform for safety evaluation and data management.

National Cooperative Highway Research Program (NCHRP) Report 350 details new crash testing procedures developed under the National Cooperative Highway Research Program. Both the American Association of State Highway and Transportation Officials (AASHTO) and the Federal Highway Administration have adopted these new requirements. NCHRP 350 requirements established a new vehicle type (i.e., 4-wheel drive pickup truck) as the standard test vehicle, and created six levels of testing.
With changes in the test vehicle and the creation of test levels, there is a need to verify the adequacy of roadside appurtenances. More specifically, safety devices incorporated into Federal-aid projects after August 16, 1998 must meet NCHRP 350 test requirements.
This study is using finite element analysis and crash tests to evaluate various types of safety appurtenances that would be used by several states that were not tested in other programs.
Selected safety devices will be tested and the adequacy of these devices confirmed. By pooling resources, significant savings will be incurred by participating states.
The Texas Transportation Institute (TTI) performed tests for NCHRP-350 compliance on roadside safety features including modified G4 guardrail with routed wood blockouts, G4 wood post guardrail with asphalt, and Oregons 42-inch tubular bridge rail on steel posts. TTI completed crash testing with the 2000P-test vehicle, and a final report was released in mid-2000. The project also developed prototypes of a steel blockout for guardrails, a new median barrier design, and an adjustable blockout to allow for settlement of the guardrail posts.
In mid-2003, another RFP for continued testing was under consideration, with additional budget required from partner state DOTs. However, this next phase, focusing on blockout designs and related issues, was not initiated due to funding constraints and reorganization of roles and key staff at participating agencies. The project is considered closed.

Many ITS initiatives employ advanced information and communication technologies, but the costs of such research and development projects are beyond the funding abilities of many states. Many of these needs are common to all parties with similar concerns; such research can be performed by the interested states as pooled-fund activities. The Transportation Management (TMC) Center Pooled Fund Study was established in 2000 by FHWA. Current pool members include the State DOTs of Arizona, California, Delaware, Florida, Illinois, Indiana, Kansas, Michigan, Minnesota, Missouri, New York, Pennsylvania, Rhode Island, Utah, Washington, Wisconsin, the I-95 Corridor Coalition, and FHWA.
The TMC PFS serves as a forum for the participants to address the operational issues that are common among traffic management centers. Through consensus and prioritization, projects that are of interest to the pooled fund member DOTs are selected and implemented.
The project is intended to enhance the operations of Traffic Management Centers and improve facility, inter-agency, and intra-agency performance under all conditions.
A. Current Projects:
This Traffic Management Center pooled fund study is valuable to the operational activities of any TMC. A great deal of useful, practical and relevant information is communicated by members and through the ongoing projects, which assist the TMC staff on a daily basis.

The primary goal of Intelligent Transportation Systems (ITS) programs is to improve the safety and efficiency of the nation's transportation system. Many of the strategies being tested in various ITS initiatives utilize advanced information and communications technologies. However, the costs of such research and development projects render such efforts beyond the funding capabilities of many states.
Many of these needs are common to all parties with similar concerns. Such research can be performed with the resources of interested states as pooled-fund activities. Members propose new projects for each upcoming fiscal year, which are then evaluated, rated, and selected.
The ENTERPRISE programEvaluation of New Technologies for Roads Program Initiatives in Safety and Efficiency is a federal pooled-fund rural ITS research program. Arizona was a founding partner in 1991. The current program membership includes the State DOTs of Arizona, Iowa, Virginia, Washington, Kansas, Minnesota, New Mexico, and Colorado, as well as Arizonas Maricopa County DOT, the Ontario Ministry of Transportation, Transport Canada, Dutch DOT, and FHWA.
ENTERPRISE sponsors ITS-related research, development, and deployment activities in the joint interests of governmental agencies and other interested parties. The objectives of this pooled-fund study are to coordinate research activities in ITS and to facilitate the timely exchange of information and research findings. Additionally, the pooled-fund will provide opportunities for joint ventures.
The project is intended to accelerate adoption of ITS technologies. As an ENTERPRISE member, ADOT has proposed, received approval, and sponsored six significant ITS projects, all of which have had direct benefits to ADOT's ITS program. The selection of these six projects is indicative of ADOT's strong ITS program and its commitment to ENTERPRISE.

Open-graded friction courses (OGFC) have largely been used since the 1970s in the United States to improve the frictional resistance of asphalt pavements. OGFC improve wet weather driving conditions by allowing rainwater to drain through the porous structure away from the pavement surface. In addition to minimizing hydroplaning during rainfall, the OGFC offer the following advantages compared to dense graded surfaces: (a) reduced splash and spray behind vehicles, (b) enhanced visibility of pavement markings, (c) reduced tire-pavement noise.
The major performance problems associated with OGFC can be classified into two categories: (1) raveling, and (2) stripping in underlying layers. The major causes of raveling in OGFC are believed to be inadequate binder film thickness, excessive aging of binder, and loss of asphalt-aggregate adhesion under freeze-thaw conditions. In 1999, the National Center for Asphalt Technology (NCAT) published a new mix design procedure for OGFC. This procedure was the result of a laboratory study designed to evaluate factors of OGFC that had led to poor performing OGFC. The NCAT procedures address the shortcomings in OGFCs design. However, the mix design procedure likely needs refining and to be field verified. In addition to the mix design procedure, guidelines for the production and construction of mixes of OGFC need to be developed.
The objective of this study will be to refine and field validate the new generation OGFC mix design procedure developed by the National Center for Asphalt Technology. Additionally, guidelines for the production and construction of the new generation OGFC will be developed.
The products of this research should replace ADOTs current OGFC design and construction procedures.
Field test sections have been constructed and evaluated.

The Southeast Superpave Center is located at the National Center for Asphalt Technology (NCAT) at Auburn University. The goal of the center is to provide assistance to Hot Mix Asphalt (HMA) contractors, departments of transportation (DOTs) and asphalt suppliers with the implementation of Superpave, and assistance in the solution of HMA mix design and construction problems. This assistance includes training, trouble shooting, conducting round-robin studies and accomplishing research studies to evaluate various aspects of Superpave and HMA technology.
The Southeast Superpave Center was established by the FHWA in August of 1995 through a cooperative agreement. The support for the center was expanded through the development and initiation of a pooled fund agreement in January 1997. The Alabama Department of Transportation is administering the program.
An annual work program is developed for the pooled fund effort. Additionally, each participant can use this program for specific research needs. The Arizona Department of Transportations (ADOT) involvement is focused on agency-specific research needs.
The objective of this pooled fund effort is to provide assistance to contractors and DOTs with the implementation of Superpave and assistance in the solution of HMA pavement design and construction problems as needed.
This is a perpetual pooled fund effort and the implementation will be contingent upon the projects that ADOT participates in.
The pooled fund develops an annual workplan of cooperative projects that lists active projects. The program is currently assisting ADOT with SPR 371, Maintenance Cost Effectiveness and the Arizona Quiet Pavement Program

The current methodology for internal design of steel and geosynthetic reinforced mechanically stabilized earth (MSE) walls was developed empirically using a mixture of limit equilibrium and working stress concepts. The current design procedures provided in the literature and design codes have been quite successful in terms of wall performance, provided that good construction practice is used. However, based on available measurements of reinforcement strain and loads in full scale MSE structures, it appears that these design procedures are overly conservative in some cases, especially for geosynthetic reinforced structures.
Because of the potential that a more accurate design procedure for internal stability of MSE walls, especially geosynthetic walls, could result in significant cost savings, the Washington State Department of Transportation (WSDOT) has funded research for the last three bienniums on geosynthetic wall internal stability design. The research already funded by WSDOT and completed or at least underway is designed to produce a new, but appropriate, design procedure for internal stability design of MSE walls. However, there are certain key variables, which cannot be fully investigated in the funded research program, which should be investigated to provide a complete and more accurate design procedure. These additional variables will be investigated in this study through a series of 3.6-m high full-scale test walls combined with analytical modeling, as well as analytical modeling of other well-instrumented full-scale case histories not analyzed in the current study.
The data and the results of the analytical modeling of these full scale test walls, including the modeling results from the steel reinforced MSE wall case histories not modeled as part of the current WSDOT study, will be used to refine and extend the internal stability design methodology developed as part of the current WSDOT study to insure that the design methodology developed is widely applicable and well founded. New parametric analyses will be conducted to accomplish this. The scope would remain limited to walls which utilize granular backfill as is true of the current WSDOT study. A research report will then be produced which summarizes all of the results obtained and which provides recommendations for designing MSE walls for internal stability. Successful analytical modeling techniques developed as a result of this study will also be provided, in a step-by-step format. External peer review will also be included as part of this project. What is the influence these concentrated/external loads have on these slope protection systems? Practical design guidance is needed in this area.
The objective of this research is to develop an improved design methodology, which more accurately predicts reinforcement loads and deformation in MSE walls, and eventually move this design methodology into design code.
The design methodology will be incorporated into standard practice.
A total of four walls (Walls 4 through 7) were constructed and studied as part of this pooled fund project. The first three walls studied were constructed prior to the pooled fund. It is estimated that there is sufficient funding for Walls 8 & 9, and maybe Wall 10, which could take the next two years to complete. In the meantime, it is proposed to have two alternatives for Wall 11 as part of the study. More than fifty percent of project work field testing is completed. Because more funding will be sought, the estimated completion time is only tentative. A request will be made for the department to contribute toward a proposed second phase if testing.

Draped wire mesh and cable mesh slope protection has been utilized by states for many years to control rockfall. The initial design and specifications for these draped wire mesh slope protection systems were developed using empirical methods by the Washington State Department of Transportation (WSDOT) in the late 1950s for slopes that were generally less than 75 feet in height. Over the years the draped wire mesh slope protection designs have been modified by other states so that nationwide there are now a large number of variations of designs, none of whose performances have been quantified.
Draped cable mesh slope protection designs were instituted in the late 1980s to accommodate larger rockfall sizes, but again these designs were based on empirical derived wire mesh slope protection designs with some modifications in terms of vertical cable sizes and spacing. Both draped wire mesh and cable mesh slope protection systems are now being installed regularly on slopes far in excess of 75 feet in height. Design guidance for draped wire mesh and cable mesh slope protection systems for slope heights exceeding 75 feet is non-existent.
Current consensus among rockslope stabilization practitioners and contractors nationally is that some elements of the currently constructed draped wire mesh and cable mesh slope protection systems may be conservative and that some of the design elements may not be required. Although this may be the case, WSDOT has experienced problems with these systems indicating that certain design elements may in fact be under-designed. The problem is that there is no clear understanding what design elements are critical to the wire mesh and cable mesh systems because the design is empirical and has never been quantified. Additionally in some states draped slope protection systems are being installed on slopes that are subjected to concentrated loads such as pockets of rock and external loads such as deep snow on flatter slopes. There is little information on what influence these concentrated/external loads have on these slope protection systems. Practical design guidance is needed in this area.
There is a substantial need to quantify the wire mesh and cable mesh designs, and to make appropriate design revisions to insure that the wire mesh and cable mesh systems are, first, safe and second, economical to construct.
There will be new standard designs developed for: wire mesh slope protection (100 feet in height), cable mesh slope protection (100 feet in height), wire mesh slope protection (100 300 feet in height), and cable mesh slope protection (100 300 feet in height). There will also be installation guidelines developed for each of the standard designs.
Research is on-going. Literature research is completed, a finite element model is built, and the team is currently working on other aspects of the project.

The lateral load capacity of pile foundations is critically important in the design of buildings and highway structures, which may be subjected to earthquake motion. Although fairly reliable methods have been developed for predicting the lateral capacity of single piles under static loads, there is very little information to guide engineers in the design of closely spaced pile groups (i.e. spacing less than about 6 pile diameters) particularly under dynamic loads. Because of the high cost and logistical difficulty of conducting lateral load tests on pile groups, only a few full-scale load test results are available that show the distribution of load within a pile group. These tests have all involved static or quasi-static loadings.
Nevertheless, the data from these limited field tests indicate that piles in groups will undergo significantly more displacement and higher bending moment for a given load per pile than will a single isolated pile. The tendency for a pile in a trailing row to exhibit less lateral resistance because of the pile in front of it is commonly referred to as shadowing. This shadowing effect becomes less significant as the spacing between piles increases. One method of accounting for the shadowing or group reduction effects is to reduce the single p-y (horizontal soil resistance vs. displacement) curve using p-multipliers.
Because of the dearth of experimental data, computer programs for pile groups have not been thoroughly validated and empirical methods are extremely restricted in their application. As a result, engineers are forced to design pile groups in a very conservative manner to deal with the uncertainty. Although numerical and centrifuge models can provide some guidance regarding these issues, a reasonable number of full-scale load tests are necessary to verify these models and provide ground truth information.
Over the past two years, Professor Rollins and his students at Brigham Young University (BYU) have conducted a series of static and dynamic lateral load tests on a full-scale pile group at the Salt Lake International Airport. The piles were 12-in. diameter steel pipe piles driven to a depth of approximately 30 ft. in a soil profile consisting of soft to medium clay. The piles were driven in a 3 x 3 pattern with a nominal spacing of 3 pile-diameters center-to-center. Static loads were applied in one direction with conventional hydraulic jacks while dynamic loads were applied in the opposite direction with a Statnamic loading device. The Statnamic device produced loads of up to 300 tons with peak accelerations between 0.5 and 2.9 g and duration of about 300 msec. These parameters are similar to what might be expected for an earthquake loading. The load in each of the nine piles was measured during both loadings so that the distribution of the loading in the pile group could be determined. Tests were also performed with a pile cap to create a fixed-head boundary condition.
As a result of the lateral load tests at the Salt Lake City Airport, significant insight has been provided regarding group reduction factors (p-multipliers), large-strain dynamic resistance, and accuracy of several computer analysis methods. There are however several unresolved issues that need to be explored with supplemental full-scale load testing.
The objectives of this research project are:
The design approach and software that are presently being used to design both single piles and groups of piles will be validated. Additional information about pile group behavior will be developed and the use of larger piles and larger pile groups will be evaluated. The eventual implementation will be in changes to the American Association of State Highway and Transportation Officials (AASHTO) Bridge Specifications.
This project is completed, however the final project report has not yet available. A TAC meeting was held in March 2002 to review the final report. It is expected that the final report will be available any time.

Understanding why some pavements perform better than others is key to building and maintaining a cost-effective highway system. In 1987, the Long-Term Pavement Performance (LTPP) program a comprehensive 20-year study of in-service pavements began a series of rigorous long-term field experiments monitoring more than 2,400 asphalt and Portland cement concrete pavement test sections across the U.S. and Canada.
Established as part of the Strategic Highway Research Program (SHRP) and now managed by the Federal Highway Administration (FHWA), LTPP was designed as a partnership with the States and Provinces. LTPP's goal is to help the States and Provinces make decisions that will lead to better performing and more cost-effective pavements.
The goal of this study is to improve the quality and quantity of monitored traffic data (volumes, classifications, and weights) on selected LTPP Specific Pavement Study (SPS) projects. The projects include:
A core objective of the SPS studies is to understand and quantify the relationship between pavement performance, truck volumes, and axle loadings.
The results of this study will be incorporated into future ADOT pavement designs.
Work is underway. This is a two-phase project. Phase I involves assessing, evaluating, and calibrating Weigh-In-Motion (WIM) systems at the SPS sites. Phase II involves procuring, installing, repairing, and maintaining the WIM equipment at the test sites.
The Phase I contract was awarded August 2003. A draft request for procurement (RFP) for Phase II was sent out for industry comment the summer of 2003. A final RFP will be solicited the beginning of 2004.

Today, technology evolution and business changes occur at steadily increasing rates. Due to constantly changing needs and influences, businesses need to modify or re-tool their processes or organizations very quickly and efficiently. These same issues apply to the public side as well, where finite resources compete for ever increasing service demands.
One additional tool to address this problem is to provide a vehicle for peer-to-peer exchange of ideas and experiences between practitioners. Through the use of video conferencing, peer-to-peer exchanges by practitioners can occur at regularly scheduled intervals on pre-determined topics. This allows agencies to maintain currency and expertise in selected areas by leveraging the experience and knowledge of other agencies. By pre-programming the experiences it also allows agencies a more efficient vehicle since the right people can be present at the right time.
The objective of this pooled fund effort is to provide a vehicle for exchanging knowledge and experience between agencies.
The program is set up to provide peer-to-peer knowledge and experience transfer. Implementation would occur through daily activities.
The program is ongoing.

The events of September 11, 2001 have heightened the national focus on security. At the state and local level, existing emergency management preparedness is being modified and upgraded in response to the threat of terrorist attacks, especially weapons of mass destruction (WMD) such as biological or chemical attacks.
Globally, transportation systems have been terrorist targets or involved as the medium for the delivery of terrorist attacks. Transportation systems and assets of all modes and types therefore are a logical focus on an intensified review regarding threat levels, vulnerability, consequences, preparedness, countermeasures and response regimes.
State DOTs around the country are updating their emergency operations plans and programs focusing not only on their external roles responding to the requirements of the state EMAs, but also on their internal programs in terms of organization, roles and relationships, communications, equipments, incident management (IM) planning, etc. These activities have tended to focus on departmental assets and highway-related facilities, but in many cases have included responsibilities for other modes over which departments have jurisdiction.
The purpose of this work is to provide support in the first stages of developing a comprehensive Transportation Security Plan.
A comprehensive Transportation Security Plan.

The Arizona Department of Transportation (ADOT) faces a huge challenge in providing safe and efficient transportation to an ever-growing number of motorists, while maintaining highways that have a minimal impact on the environment. One group of wildlife that has received relatively little attention by transportation professionals and conservation biologists is amphibians and reptiles. Amphibians and reptiles are present in every ecosystem in the United States. Studies have shown that extremely high numbers of amphibians and reptiles are killed on roads in Arizona, throughout the United States, and worldwide. Although exemplary research on mitigating the effects of roads on large ungulates has come to the forefront recently in Arizona, very little is known about how to make roads more permeable for small animals like amphibians and reptiles.
This project will address some of these issues with a specific focus on providing information on the use of highway crossing structures by the Flat-Tailed Horned Lizard (FTHL) that can be applied to management decisions regarding highway design and maintenance.
The scope of work has not been developed. Project focus and detail will be determined by the TAC)
Project results will provide guidance on individual project habitat mitigation efforts.

Extreme speeding on Phoenix-regional urban freeways has reached a critical level. It is technically very difficult on a multi-lane freeway to obtain accurate speed data to document the problem. A variety of ITS system(s) now exist to accurately collect such data, along with camera-based technology to effectively enforce the speed limits. Evaluation of practical ITS enforcement tools and methods is a practical, logical, and urgent step to identify ways to fight a growing safety and economic problem.
ADOT needs to evaluate what kind of automated enforcement system(s) now exist to enforce speed limits on urban freeways. Deployment issues identified in other jurisdictions must be assessed. This project will assess and identify the best resources to accurately measure the freeway speeding problem, and it will fully enable a field test as a future second phase.
The project will survey other agencies, follow up with vendor contacts, review deployment issues, and develop system and plan recommendations. It will prepare a conceptual design for a trial deployment and field test, defining equipment, infrastructure, sites, and system budget. The key tasks are:
Sound data is required to establish the ability, political will, and/or authorization to conduct a field test of automated enforcement systems on state freeways and highways. This research project would provide that information, and it would fully enable a field test in a future second phase. The results of this project will support the decisions needed for Arizonas leadership to then authorize and fund that field test.
This project has not yet been initiated.
