System Performance Criteria for the WILMAPCO Congestion Management Process (CMP)
Multiple data sources were used to perform a system-wide performance analysis to identify recurring and non-recurring congested locations. They Include:
- Severe Congestion Status from Traffic Operation Management Plan (TOMP)
- Total Daily Hours of Person Delay (PHED) from TPM (PM 3) Performance Measures
- Intersection Level of Service—Critical Movement Summation
- Statewide Intersection Crash Assessment & Rankings
- Travel Time Index (TTI) from NPMRDS Expanded Dataset
