TMCs considered in this project include those that are normally responsible for the operation and management of ITS field equipment, freeway management, signal systems management, incident management, and corridor management. The purpose of this project was to identify key measures that can be used to execute operational strategies and methodologies that can be used to implement those measures, including structures for organizing the data and the algorithms and processes required.
The archived data management systems (ADMSs) that provide a key element for this project support the following TMC functions:(1)
When coupled with performance measures that use these data, the results from applying the methodologies addressed provide the basis for developing reports and presentations that justify project investment to decisionmakers and the public. Such results also form the basis for future resource allocations and improvements in operations. In many cases, agencies develop reports that provide results to the public on the performance of TMCs and ITSs that they manage.
This project emphasizes the computation of measures from data that are commonly available to TMCs from traffic detectors in the systems managed by those TMCs. Other data, such as crash record data, are also required for benefit-cost evaluations. This report focuses on outcome-oriented measures rather than output-oriented measures.
