Federal Highway AdministrationUS Transportation CollectionThis report documents the use of the National Performance Monitoring Research Data Set(NPMRDS) for the computation of freight performance measures on Interstate highways in Washingtonstate. The report documents the data availability and specific data quality issues identified withNPMRDS. It then describes a recommended initial set of quality assurance tests that are needed beforeWSDOT begins producing freight performance measures. The report also documents the initial set ofperformance measures that can be produced with the NPMRDS and the specific steps required to do so.A subset of those metrics was tested using NPMRDS data, including delay and frequency of congestionto illustrate how WSDOT could use the freight performance measures. Finally, recommendations andthe next steps that WSDOT needs to take are discussed
