The National Performance Management Research Data Set (NPMRDS) is a vehicle probe-based travel time data set acquired by the Federal Highway Administration (FHWA) for its use in various performance measurement programs, such as its Freight Performance Measures, Urban Congestion Report, and other programs. The NPMRDS is also provided to state departments of transportation (DOTs) and metropolitan planning organizations (MPOs) for their performance management activities.
The NPMRDS is an archived speed and travel time data set procured and sponsored by FHWA, including associated location referencing data.

Data from 2017 forward are provided by a team consisting of the CATT Lab at the University of Maryland (UMD), INRIX, 1Spatial Consulting, the Texas A&M Transportation Institute (TTI), and KMJ Consulting—collectively referred to as the UMD team.
