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

2022 CMP Performance Measures and Identified Corridors
The map below contains the most recent congestion performance measures for the WILMAPCO region. These measures serve as the basis for identifying the top corridors for more in-depth analysis and for an input into the project prioritization process.
TOMP AM Peak Severe Congestion Status
Weekday areas with deficient Travel Time Reliability (TTR) from 7-9am
CMP Hot Spots.
TOMP PM Peak Severe Congestion Status
Weekday areas with deficient Travel Time Reliability (TTR) from 4-6pm
TOMP Summer Mid-Day (10am-6pm)
Summer Weekends areas with deficient Travel Time Reliability (TTR)
Statewide Intersection Crash Rankings
Annual PHED
