120075_I-95_banner_R3_V1The I-95 Corridor Coalition’s Vehicle Probe Project (VPP) began in 2008 with the primary goal to provide Coalition members with the ability to acquire reliable travel time & speed data for their roadways without the need for sensors and other hardware. The VPP surpassed the original expectations and also provided real-time & historical tools for operations and planning. The VPP is moving forward again with a “traffic probe data marketplace”. Three highly qualified vendors (HERE, INRIX and TomTom) were selected by a team of agency members to provide data under the new contract. This structure gives agencies the opportunity to select the vendor that best suits their individual needs at a cost that was negotiated for the Corridor. As part of this new contract, the data is still subjected to rigorous validation for reliability. In addition, all data, regardless of vendor, is available to each of the participating agencies providing a truly shared effort.
