Transportation System Management and Operations (TSMO) is an integrated approach to optimize the performance of existing infrastructure by implementing multimodal, intermodal, and often cross-jurisdictional systems, services and projects.
Rapidly increasing congestion, constraints on capacity expansion, and limited financial resources nationally and locally are causing concern for transportation agencies and their customers. The ADOT planning process has traditionally focused on constructing new roadways and widening existing highways; however, current challenges associated with transportation system reliability, safety, and security require new methodical strategies targeted to improve operations of the existing system.
Commuters and freight shippers are increasingly sensitive to delays affecting tightly scheduled personal activities and/or manufacturing distribution procedures. Regional growth in traffic volumes often means that even small disruptions can have a significant ripple effect on transportation system performance. There is also an increasing recognition of the significance of road construction, weather conditions, traffic incidents, special events, and emergency situations and the effects of these events on the reliability of the transportation system. It is estimated that approximately half of the regional traffic congestion is caused by temporary disruptions that reduce capacity of the of the roadway (“non-recurring” congestion).
Transportation System Management and Operations (TSMO) is an integrated approach to optimize the performance of existing infrastructure by implementing multimodal, intermodal, and often cross-jurisdictional systems, services and projects. This includes regional operations collaboration and coordination activities among transportation and public safety agencies. TSMO is not routine road maintenance like resurfacing or guardrail replacement. TSMO strategies improve system efficiency, enhance public safety and security, reduce traffic delays of road users, and improve access to information for travelers. The emphasis of TSMO is an outcome driven, performance-based system. It is critical that regional operations objectives can be measured since they have importance on a regional level. TSMO strategies include but are not limited to traffic safety, traffic incident management, travel information services, roadway weather information, freeway management, connected vehicles and automated vehicles, traffic signal systems and coordination, work zone management, managed lanes, emergency response and Homeland Security, freight management, active traffic management, and new technologies that are rapidly occurring.
