16. Abstract

The Federal Highway Administration third performance management rule (PM3) measures support system performance, freight movement, and the Congestion Mitigation and Air Quality (CMAQ) Improvement Program. The PM3 measures include the National Highway Performance Program (NHPP) Travel Time Reliability (reliability) measures and the freight reliability measure. They also require applicable metropolitan planning organizations (MPOs) to measure two CMAQ traffic congestion measures—Annual Hours of Peak Hour Excessive Delay (PHED) per capita and Non-Single Occupancy Vehicle (Non-SOV) share—and CMAQ Total Emissions Reduction. Through the use of case studies, examples, and other research, this report describes practices to communicate PM3 measures, metrics, and targets.
