Traffic Maintenance and Management

Traffic Operations Center

The 2,100-square-foot control room includes 32 video monitors mounted on a wall and large screens used to display traffic speed and weather information. There are four workstations in the control room. Operators at two of the stations monitor traffic in the Phoenix metro area, and the operators at the other two stations monitor traffic throughout the remainder of the state. There are 15 operators that work various shifts to ensure that there is 24-hour coverage in the control room. TOC staff constantly monitor the Department of Public Safety (DPS) Computer Aided Dispatch (CAD) system, speed maps and CCTV monitors. When staff become aware of an incident, they use cameras to verify the incident and determine the appropriate response (e.g., dispatch DPS and/or ADOT staff, post messages on one or more Dynamic Message Signs [DMS], enter information into the Highway Condition Reporting System (HCRS), which automatically places this information into the 511 system, etc.). ADOT staff anywhere in the state of Arizona can also input information into HCRS regarding construction and maintenance activities on the 6,000-mile state highway system. Five valley television stations have access to live CCTV camera feeds from ADOT's cameras to show freeway conditions.
