utf8 dataset dataset ISO 19139 Geographic Information - Metadata - Implementation Specification 2007 PM3 Performance Measures: National performance management reliability and traffic congestion measures, known as PM3 measures, are used to assist in identifying and prioritizing congested locations and for developing strategies to improve mobility and reliability. They include Level of Travel Time Reliability (LOTTR), Peak-Hour Excessive Delay (PHED), and Truck Travel Time Reliability (TTTR). These measures have been adopted by the Federal Highway Administration (FHWA) effective May 20, 2017. The intent is to have DOTs, MPOs and other planning partners better align proposed project improvements through performance-based planning and programming. The measures are derived from the National Performance Research Dataset (NPMRDS) and are mapped by roadway segment for 2021. Road Network with PM3 Performance Measures.
