National Performance Management Research Data Set (NPMRDS)

The FHWA has acquired a national data set (called NPMRDS) of average travel times on the National Highway System for use in its performance measures and management activities. TTI is a part of the NPMRDS project team and provides geospatial data integration (i.e., GIS conflation) services. In particular, TTI conflates selected HPMS attributes onto the private-sector TMC highway network used in NPMRDS.

You can find more information on NPMRDS on FHWA’s Operations Performance Measurement Program website. Use the login portal for NPMRDS if you wish to view NPMRDS data. To gain access, you must first complete a data sharing agreement.
