FHWA selects Inrix to supply traffic data for roadway performance assessment tool


Connected car services and transportation analytics provider Inrix has announced that its traffic data will be used by the US Department of Transportation’s (USDOT) Federal Highway Administration (FHWA) and state and regional agencies to assess travel reliability, congestion and emissions.

FHWA’s National Performance Management Research Data Set (NPMRDS) is used by states to monitor system performance. Beginning in July 2017, all state departments of transportation (DOTs) and metropolitan planning organizations (MPOs) can use Inrix travel time data to establish performance targets and report on progress. NPMRDS provides comprehensive and consistent data for passenger and commercial freight roadway performance across the National Highway System (NHS), as well as over 25 key Canadian and Mexican border crossings. NPMRDS is defined as the baseline dataset to meet the newly established federal congestion and freight performance reporting regulation.

Inrix has partnered with the Center for Advanced Transportation Technology Laboratory (CATT Lab) at the University of Maryland (UMD) and other industry leaders to support NPMRDS through 2022. As the prime contractor, CATT Lab will operate the portal that transportation planners will use to analyze, visualize and understand road performance.

Inrix and UMD have a long and successful partnership in delivering projects and services to public agencies, including the I-95 Corridor Coalition’s Vehicle Probe Project. Texas A&M Transportation Institute (TTI) will assist Inrix in establishing and maintaining high quality NPMRDS GIS location referencing network files based on FHWA’s Highway Performance Monitoring System’s NHS network. KMJ Consulting Inc., also a contributor to the I-95 project, will triage customer support and aid in project management.

Inrix provides some of the widest coverage and most accurate information available by using advanced fusion technologies to integrate the full range of travel data sources to create high quality traffic services. The company aggregates GPS probe data from a wide array of commercial vehicle fleets, connected cars and mobile apps, to provide real-time, historical and predictive traffic information, with widespread XD and TMC coverage across the USA.

“We are proud to supply the underlying traffic data that will be used to monitor, measure and improve many of our nation’s key roadways,” said Scott Sedlik, VP and GM of the global public sector at Inrix.

CATT Lab director Michael Pack commented, “Inrix real-time traffic services will help public agencies actively measure, report and manage traffic. The quality of the data plays a fundamental and necessary role in NPMRDS to accurately assess our nation’s roadways.”
