Congestion Management Process

Home » Our Work

The Congestion Management Process (CMP) monitors the transportation network to determine the locations and sources of congestion in the Boston MPO area, and identifies and implements strategies that alleviate congestion. The Boston Region MPO´s CMP monitors the performance of the following types of transportation facilities in the MPO area:

  • Freeway and arterial roadways
  • Intersections
  • Transit
  • Park-and-ride lots
  • High-occupancy-vehicle (HOV) lanes, and
  • Bicycle and pedestrian facilities

About the CMP

CMP monitoring leads to recommendations for studies to be programmed in the Unified Planning Work Program (UPWP) and for improvements to be implemented through the Transportation Improvement Program (TIP) and Long-Range Transportation Plan (LRTP). Federal legislation requires that, in metropolitan areas that do not meet the national ambient air quality standards, capacity-increasing projects for single-occupant vehicles be part of an approved CMP.

In 2012, the MPO established a congestion management committee to ensure that the appropriate congestion mitigation strategies are evaluated and promoted for funding in the UPWP, TIP, and LRTP.
