The I-95 Vehicle Probe Project is a groundbreaking initiative providing comprehensive and continuous travel time information on freeways and arterials using probe technology. July 1, 2011 marked the start of the fourth year (Coalition Project Year 19) that Vehicle Probe Project (VPP) data is being provided to our members.

There are now 7,000 centerline freeway miles, more than 20,000 freeway and arterial miles in all, including continuous coverage of the I-95 corridor from New Jersey through Florida. Coverage also exists in Rhode Island. The network includes full coverage of freeways and major arterials in North Carolina and the Tidewater area of Virginia, full or nearly full coverage of limited access roads in New Jersey, Maryland and South Carolina and the northern and eastern portions of Florida. In addition, coverage now includes ramps at 160 major highway-to- highway interchanges, with all states having interchanges included except Georgia.

Agency Participation – 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.

Numerous Uses for the Data – 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

Performance Measures Tool – Continuing the momentum in performance analysis, the newest initiative from the Coalition is the Vehicle Probe Project Suite. The basic tools include:

• Bottleneck and Incident Dashboard
• Massive Data Downloader
• Congestion Scan
• Historic Tools
• Bottleneck Ranking

UMD CATT Lab made the VPP suite to participating agencies. For the training video, please visit http://vpp.ritis.org/suite/screencast/.

Key results to date include:

• Better Traffic Monitoring at a Fraction of the Cost. In addition to providing states with a more complete view of traffic conditions on their major roads, INRIX’s real-time traffic information has helped states more effectively allocate limited traffic operations resources. 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.2 Similarly, South Carolina DOT claimed that maintaining coverage to gain speed data for over 300 miles of South Carolina roads using traditional methods is equal to the total cost of the INRIX speed and travel time data for 1,200 miles of roads.² 
• Faster Emergency Response. In addition to seeing real-time traffic conditions for more roadways and across state lines, member states have been able to more quickly identify and respond to traffic issues. In New Jersey, traffic operations staff identified a serious accident on a stretch of I-80 during a surprise October 2008 snowstorm that they previously wouldn’t have been able to see using their CCTV system. Without the Vehicle Probe Project traffic monitoring site, response to the 2nd incident would have been delayed by as much as an hour. NJDOT estimated that the expedited response to the second incident translated into $100,000 in savings in user delay costs. ²
• New and Improved Traveler Information Services. In a region of 100 million people where more than 100,000 cars and trucks travel the I-95 corridor every day, the Project has delivered new and improved traveler information services that help residents and businesses better plan their trips including:
  
  
  • On the road: Travel Times on Dynamic Message Signs are driven by VPP data in Maryland, Virginia, and South Carolina.
  • On the phone and online: 511 phone and web services in New Jersey, Pennsylvania, Maryland, North Carolina, South Carolina and Florida utilize VPP data to provide services.

The objective of this project is to create a seamless traffic monitoring system that spans the eastern seaboard delivering travel times and speeds on freeways and arterials using probe technology. The INRIX system fuses data from various sources to present a comprehensive picture of traffic flow. Member agencies have found numerous uses for the data beyond simply travel information (the original use at the project inception).
