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.

As the value of the data from the Vehicle Probe Project is realized through the various applications and the continued quality via the validation efforts, the member states have increased their commitment to this project. In fact, all of the participating states have committed their own funds to continue this project and many have increased their coverage far beyond the initial core area.

I-95 Corridor Coalition member agencies have found many uses for the vehicle probe data, including:

  • Operations Center (Real-Time Traffic Monitoring)
  • TMC Software Integration
  • Cross-border Incident & Traffic Monitoring
  • Travel Times on Signs
  • Travel Times on Websites
  • Travel Times on 511 IVR
  • Traffic Tile Overlay on 511 Site
