The CMAP congestion management process (CMP) is a systematic method of managing congestion that provides information on transportation system performance and on alternatives for alleviating congestion and enhancing mobility. The CMP is required by federal legislation and is governed by federal rules. Legislation requires that any federally-funded transportation project that significantly increases the capacity for single-occupant vehicles in our area has to be derived from a CMP. In October 1997, the MPO Policy Committee approved the Northeastern Illinois Congestion Management System, which now functions as the regional CMP.
The CMP is integrated into the transportation development process. Planning, programming and project development efforts by the region’s highway and planning agencies have standardized process components that either directly investigate congestion reduction strategies or address other issues, such as air quality, that result in congestion mitigation.
