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

www.I95Coalition.org I-95 Corridor Coalition Vehicle Probe Project 8

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

www.I95Coalition.org I-95 Corridor Coalition Vehicle Probe Project 9

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.
