NJDOT - What They Needed and Why

      Most densely populated state in US Most DMS statewide w/o travel times Need instrumentation Need incident detection other than ESP, PD and the media Limited resources to instrument the entire system Could not handle the O&M of statewide instrumentation

What NJDOT Did!

Leveraged the I-95 Vehicle Probe Contract • 958 miles covered (DOT & Authority) • 534 miles by I-95 CC • Addl. 424 miles ($1.2M for 3 years) • • Went from less than 5% to 35% covered Displayed in NJ TOCs to monitor the system

What NJDOT is Doing

 Incident Detection alerts from systems  Travel speeds on 511/Web  Interactive Travel times on 511/web  Expanding instrumentation as needed to supplement INRIX and existing.

 Data Fusion of INRIX, RTMS, Transmit and other traffic data systems to feed 511/Web and DMS

NJ Story - saves $100K in User Costs

 Reduced delays and no secondary incidents  Estimated roughly a one-hour reduction in incident detection time • translated to a $100,000 savings to users  Without the I-95 CC/INRIX data, the incident would have gone undetected for a foreseeable time.

What NJDOT Learned

 Leveraging this contract worked  I-95 Corridor Coalition VP data by INRIX gives us a Statewide view of the transportation system not had previously  Need other means of detection to fill-in
