Congestion Management Process

Home » Projects, Plans, & Programs » Congestion Management Process

MPOs with a population exceeding 200,000 in population are required to carry out congestion management processes, or CMPs. CMPs is described in Federal law, and are intended to examine the sources of congestion, evaluate alternative strategies for alleviating congestion, and monitor the performance of these strategies. MPOs are required to assess strategies that are not traditional single-occupant vehicle (SOV) expansion projects (such as roadway widenings and new construction of general purpose travel lanes) before programming roadway capacity expansion construction projects.


CRTPO goals, objectives and performance measures for the CMP

CMP – Goals, Objectives, and Performance Measures

Goal: Manage Congestion
Objectives:Performance Measures:
Develop congestion management measures% of Roadway Miles at a Travel Time Index (TTI)/Level of Service:
– 1.1-1.49 TTI/Level of Service E – Moderate Congestion
– 1.5 or more TTI/Level of Service F- Heavy Congestion
Reduce non-recurring congestion durationNo. of crashes per 100 million vehicle miles or travel (MVMT), related to the statewide average
Consider full range of congestion management strategiesWere all reasonable techniques and strategies considered — Yes / No?
Improve the resiliency, redundancy, and reliability of the transportation networkExtract data from HERE – Use buffer, or other indices

CRTPO has also identified 60 congested corridors to be evaluated as part of its CMP. The CMP congested corridors have either been identified based on available congestion data, stakeholder input from the CMP Task Force, or because a widening project to add capacity is programmed along the corridor. The intent of identifying congested corridors for the CMP is to assess if other strategies, besides a traditional widening project, could help alleviate congestion on the facility. The CMP is also updated regularly to make sure the corridors being evaluated are the most appropriate for considering alternative strategies and managing congestion throughout the CRTPO planning area.

The CMP is one way the CRTPO plans for future improvements to its transportation network. It is a process that provides information to help influence investment decisions and project programming.

Planning Process

Next Steps

  • Compile and document findings in a CMP Report
  • Perform subsequent updates every four to five years – Verify that the CMP continues to be applicable to CRTPO’s vision, goals and objectives.
  • Hold periodic meetings of the CMP Task Force – Schedule regular meetings throughout the year, such as quarterly or semi-annually to identify and address changing conditions or requirements.
