The primary impetus for the creation of the ITSRC is to utilize the extensive technological resources and staff expertise of the NJIT Transportation Center to assist NJDOT in developing and implementing a comprehensive ITS management strategy. This strategy will involve systematic deployment of ITS tools at selected target locations throughout the State highway network that are expected to yield the largest benefit in terms of congestion reduction and improvement in traffic safety.
New Jersey travelers are facing the unprecedented congestion levels on New Jersey roads. NJIT estimated the cost of congestion in 2003 at $8 billion . The breakdown by counties is given in Figure 1. New Jersey’s highway network operates at its maximum capacity and a small disruption in traffic flow results in a disproportionate increase in delay.
It has been recognized that New Jersey can not “widen its way” out of the congestion problem and that NJDOT ought to use “smart technology” as a way of improving the throughput on its highways . With limited resources and political opposition for road widening and other capacity enhancements, the attention has shifted to getting more out of existing infrastructure through the use of ITS as a mean of increasing throughput and overall efficiency of the transportation system. The idea is to implement a better management of traffic flow using strategies such as traffic metering and technologies for detecting the changes in traffic flow and providing corrective action so that the network can continuously perform at its optimum level. Half of congestion can be attributed to so-called non-recurring congestion, namely congestion caused by random incidents such as accidents and disabled vehicles on a roadway.
The investment in ITS technology can be seen as the offset to the congestion costs. The improvements in network performance in strategic areas can result in a substantial decrease in congestion costs and improved mobility.
The benefit of ITS is identified in the FHWA report “ITS 2005 Update, Benefits, Costs and Lessons” . The guiding principle of the future ITS strategy is to achieve the highest possible payoff from the use of scarce financial resources.
The primary objective of this project is to enhance NJDOT’s ITS resources through the technology assessment, evaluation of ITS implementation strategies and scenarios, applications of advanced modeling and simulation tools for corridor planning, and technology transfer. The new center will be a premier resource for NJDOT’s planners and engineers when it comes to ITS, including both information about state-of-the-art ITS and expertise in developing, implementing, and evaluating ITS applications. It will also be a source of data and models necessary for generating reliable measures of system performance used in a decision making process. In that manner, ITSRC will:
1. Provide on-call support to NJDOT for the ITS technology assessment.
2. Assist NJDOT or lead development of ITS simulation models.
3. Conduct evaluation studies of corridor improvements
4. Offer training to NJDOT personnel in the application of ITS technologies.
