SBJ Staff Report

Oct 12, 2011 - The I-95 Corridor Coalition, the University of Maryland and INRIX announced a 3-year extension and expansion of a program today that significantly improves how state and federal transportation agencies allocate billions of dollars in transportation funds. 

The I-95 Coalition Vehicle Probe Project (VPP), first operational in 2008, uses crowd-sourced traffic data and advanced analytics techniques to turn billions of data points into insights that are transforming the manner in which member states build, manage and measure their road networks.  The project now provides INRIX real-time and historical traffic information for more than 20,000 miles of roads across 10 states along the I-95 corridor. 

"By expanding the program, we expect to achieve even greater gains from smarter investment in our transportation networks and help our members provide improved service to travelers," said George Schoener, executive director, I-95 Corridor Coalition.  "The significance of the project to our member agencies is very clear, with all 10 states investing some level of their own resources in the project, in some cases committed out to 2014."

Key elements of the project's expansion over the next 3 years include:

Massive Coverage Expansion.  The project coverage increases from 5,000+ miles of road coverage in 8 states to more than 20,000 centerline miles in 10 states.  

In addition to complete freeway coverage, North Carolina is investing in coverage across their entire road network gaining access to more than 15,000 miles of highways, interstates, arterials and secondary roads of INRIX real-time and historical traffic information statewide – the first state to standardize on INRIX data – in addition to data on I-95.     

Complete I-95 coverage across Georgia, Florida, Pennsylvania and Virginia including interstates around Savannah, most South Florida limited access roads and all freeways and arterials in Virginia's Hampton Roads area are included.

INRIX data for highway-to-highway interchanges in urban areas offers agencies insight into real-time traffic conditions in areas previously blind to traffic operations.  Many complicated urban area interchanges are now available for viewing.

The expansion permits expansion of the numerous services offered by the Coalition's members and relied on by hundreds of thousands of drivers everyday including:

- Covering more than 8,000 centerline miles, the free site is designed to assist the millions of multi-state travelers in the I-95 Corridor by providing real-time traffic information and travel times for key destinations across state lines, complimenting in-state 511 services.

- 511 phone and web services in New Jersey, Pennsylvania, Maryland, North Carolina, South Carolina and Florida utilize VPP data to provide services. Georgia is not participating.

- Travel Times on Dynamic Messages are driven by VPP data in Maryland, Virginia, and South Carolina.

Through a complete, precise view of traffic conditions across their road network, the Vehicle Probe Project not only helps target investment in roads and transit in the most critical areas but delivers improved traffic operations at reduced cost.  According to North Carolina DOT where previous approaches to gathering traffic data had a life cycle cost of nearly $50,000 per mile, INRIX vehicle probe data has been proven to deliver more coverage at about 25 percent of the per mile life cycle cost.(1)"
