  1. I-95 Corridor Coalition – Vehicle Probe Project (VPP) INRIX Data Evaluation January 3, 2012

  2. Speed and Travel Time Monitoring • Present day – GPS Floating Car Method • Average of 7 trials in each direction • Data collection during peak periods • Future – Vehicle Probe Data • Blends use of state installed sensors, commercial fleets, and consumer GPS

  3. INRIX • Private sector provider of traffic information • Independently validated by the I-95 Corridor Coalition Vehicle Probe Project • Conditions calculated and updated every minute • 100% detection of all freeway slowdowns; travel time accuracy above 95% • 99.9% availability

  4. Advantages of Probe Data • Continuous monitoring (24/7/365) • Probe-based speed data is superior to location-fixed detector speed data • Complements other traffic data sources; enables more robust congestion analyses

  5. Issues • No traffic volumes • Technical details regarding data collection and processing remain unrevealed • Must rely on the VPP verification process • Current VPP coverage is limited (esp. arterials) • Uncertainty of funding for future data purchases

  6. RITIS • Regional Integrated Traffic Information System • automated data sharing, dissemination, and archiving system • functions include—the real-time fusion and exchange of regional transportation data; and data archiving • University of Maryland CATT Lab

  7. RITIS – VPP Interface

  8. Conclusions • VPP data shows congestion in the same locations as traditional GPS floating car trials • Arterial coverage currently insufficient • VPP – freeways • GPS – arterials & corridor studies (BRAC)
