Traffic Operations Centers
The New Jersey Department of Transportation's (NJDOT) Traffic Operations Centers (TOC) represent the nerve centers for all transportation operations in the state. The job of the TOC is to manage the flow of traffic on the highways and provide a coordinated response for traffic incidents statewide. Annually, there are approximately 7,000 or 20 incidents per day. The total incident duration in New Jersey has declined from an average of 2.75 hours in 1995 to approximately 43 minutes in 2015.
NJDOT currently operates two high-tech Traffic Operations Centers:

- Traffic Operations Center North - part of the Statewide Traffic Management Center (STMC) in Woodbridge, New Jersey. Coverage is provided to the northern region counties of Bergen, Essex, Hudson, Hunterdon, Middlesex, Morris, Passaic, Somerset, Sussex, Union and Warren.

Traffic Operations Center North
Traffic Operations Center North, a part of the STMC in Woodbridge, provides for a seamless transportation system through a 24/7 Operations Center jointly operated by NJDOT, the New Jersey Turnpike Authority (NJTA) and the NJSP. These agencies share a common command floor to facilitate a faster and more comprehensive response to any situation that may impede the free flow of traffic. The STMC serves four functions:
- Normal NJDOT daytime operations for the northern part of the state (4 am - 8:30 pm, 7 days a week).
- Evening/weekend operations for the entire NJDOT transportation system (8:30 pm - 4 am, 7 days a week).
- Operations for the entire NJTA transportation system.
- Coordination of any major traffic event that could impact both a toll road and/or a state jurisdiction highway.
