Abstract:The North Carolina Department of Transportation (NCDOT) operates several traffic management centers across the state
along with accompanying field devices such as traffic condition data stations, traffic surveillance cameras, and variable
message signs in addition to several regional incident management assistance patrols (IMAP). These centers currently operate
independently in an environment without dedicated center-to-center communication or seamless interaction. Efficient system
operation and management at the corridor and regional levels are severely hindered by this lack of integration. In order to
remedy this unacceptable situation thereby unleashing the potential for significantly reducing delay and increasing system
efficiency and reliability, NCDOT plans to procure a statewide ATMS systems.
This ATMS procurement was planned to occur during the performance of this research project. However, the procurement
was delayed. Nonetheless the project achieved many of the original project goals. Although the baseline period did not come
to an end during the project, the research established the framework for data assembly and baseline performance assessment.
The project included a comprehensive review to the state of the practice and research in ATMS performance measurement
and provided justification, data needs, and calculation methods for eighteen recommended performance measurements. The
project also developed and tested a method for categorizing route performance based on analysis of full travel time
distributions and developed and prototyped a multi-level reporting system for ongoing monitoring and assessment of ATMS
performance.
