WSDOT currently uses freeway reliability measures as input to decision making for urban freeways and to analyses for major investment studies. It wants to expand its ability to perform those analyses to other, less urban locations in the state. This SHRP2 project is designed to build the system needed to incorporate the reliability of roadways into WSDOT’s planning, project identification, and prioritization processes statewide. This project will also be directly coordinated with the Department’s efforts to more fully integrate traffic systems management and operations (TSMO) strategies into its planning, project selection, and programming functions. In addition, WSDOT is developing and deploying truck freight performance monitoring and reporting systems. The software developed for this project will produce both freight performance measures and measures that report on overall roadway performance. The resulting software and data system will provide WSDOT with new tools that allow it and the Puget Sound Regional Council to examine roadway performance throughout the state’s National Highway System.
