FRAMINGHAM – A coalition of 16 American states is betting GPS data from hundreds of thousands of vehicles will increase safety on one of the busiest stretches of highway in the U.S.

Interstate 95 between New Jersey and North Carolina is one of the most frustrating and crammed stretches of road for drivers, but the I-95 Corridor Coalition hopes the project, to start this summer, will smooth things out. The group recently awarded a four-year, US$5 million contract to Inrix Inc. in Kirkland., Wash., to take traffic data provided by Inrix and use it to update police, traffic engineers and motorists with traffic conditions along 2,500 miles of I-95 and nearby roadways.

The data will be used to update travel time on roadway alert signs, 511 systems, incident management systems used by first responders, Internet-based traveler information systems and other systems.
