Traffic analytics company Inrix announced Oct. 11 that it expanded its coverage to include 40,000 miles of roads across 14 states, making it the largest traffic service in the world, according to a press release. Funded by a $3.2 million grant from the Federal Highway Administration, the Vehicle Probe Project (VPP) now provides real-time traffic information for freeways in Maine, New Hampshire, Massachusetts, Connecticut, Maryland, Rhode Island and the District of Columbia. Previously, North Carolina, South Carolina and Virginia had real-time traffic data since the inception of the program, which is led by the I-95 Corridor Coalition, the University of Maryland and Inrix.

“Our ability to continue expanding this program is a direct result of the proven value the project delivers for member states in terms of improved operations, better planning and performance measurement," said George Schoener, executive director of the I-95 Corridor Coalition. “By expanding coverage to four New England states for the first time, nearly every coalition state is tapping the VPP to meet their operational needs as well as the new performance measurement requirements of the recent federal legislation, MAP-21.”

The VPP uses crowd-sourced traffic data and analytics to provide information that is updated every minute for workers in 14 states and the District of Columbia. The vehicle speed data provided is accurate within 2.5 mph, according to a press release. “Better information means improved operations, more precise planning and better performance measurement,” said Rick Schuman, vice president and general manager of public sector for Inrix. “We look forward to continued collaboration with the coalition and its member agencies to better serve the traveling public.”
