www.I95Coalition.org I-95 Corridor Coalition Vehicle Probe Project 6
NJDOT Traffic Operations
2700 linear miles (2300 DOT)
800 Freeway/Toll miles Two Operations centers (Co-located with NJTA)

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

Where NCDOT Was…..• 50 miles in the Charlotte area
• 75 miles in the Raleigh area
•125 miles / 1100 miles = 11% covered
www.I95Coalition.org I-95 Corridor Coalition Vehicle Probe Project 18
Where NCDOT Needs To Be…..
• ALL INTERSTATES
• 1100 miles of coverage
www.I95Coalition.org I-95 Corridor Coalition Vehicle Probe Project 19
Why NCDOT Needs More…..• SECTION 1201 - Real-time System Management Information Program
• Customer Expectations
• Performance Measures
• Better Management Of Roadways
www.I95Coalition.org I-95 Corridor Coalition Vehicle Probe Project 20
How Data Is Used… Incident Detection Travel Information
• Website
• 511
• DMS Route/Corridor Management Event and Emergency Management Planning
www.I95Coalition.org I-95 Corridor Coalition Vehicle Probe Project 21
Incident Detection
DETECT: in areas not covered or have gaps in ITS coverage
VERIFY:• Dispatch IMAP• Communicate with Law Enforcement

Conclusions I-95 Corridor Coalition is excited by the
progress Encourages the use of VP data by its
members Looks forward to continued system
expansion and continued use.
