The Transportations Research Board’s (TRB) National Cooperative Highway Research Program (NCHRP) Report 664: Measuring Transportation Network Performance reviews ways to track transportation network performance through the development of new, or integrating existing, performance measures from different sources. Congestion management, linking planning and operations, and corridor coalitions are strategies available to agencies to build consistent transportation performance measures. Monitoring transportation network performance is important because it allows transportation professionals to easily identify areas that are under performing on a consistent basis throughout a system and provides insight into where future transportation investment will be needed.
CMAP currently measures the performance of the transportation system through its Congestion Management Process and the forthcoming regional indicators project, MetroPulse.
