The WILMAPCO's congestion management process begins with System Analysis/System Determination, which entails identifying the system (mode and networks) for consideration.

Next are the Congestion Performance Measures, which entails identifying congested corridors and isolated locations of congestion based on established performance measures. The performance measures are:

Third is Strategy Evaluation, which entails determining mitigation measures that apply to each corridor and evaluating congestion mitigation strategies in priority order. The priorities are:

  1. eliminate trips or reduce VMT,
  2. shift trips away from automobile to some other mode,
  3. shift trips from SOV to HOV auto/van,
  4. improve roadway operations, and
  5. add capacity

These steps are then repeated.

This process feeds into the next phase of the process, the WILMAPCO Regional Transportation Plan (RTP) Project Pipeline/Needs Inventory, during which projects from strategy evaluation are submitted to the state DOT project pipelines for consideration and addition to the WILMAPCO Aspirations List. This then leads to Project & Problem Prioritization, during which aspirations projects from the RTP are put through the WILMAPCO prioritization process for inclusion in the 4-year Transportation Improvement Program (TIP) and the statewide Capital Transportation Plans (CTP). During this step implementing agencies also conduct other prioritization and analysis of projects. Next is Project Implementation: TIP/CTP Programming. Finally there is System Monitoring/Project Effectiveness, which entails tracking regional congestion trends and effectiveness of implemented projects based on performance measures.
