Michael Baker Jr., Inc. Page 1 **Control Measure:** Reduce delays and idling emissions associated with accidents and incidents by providing emergency service patrols and other systems to help detect, respond and decrease the duration of these events. **Description:** Non

- recurring congestion associated with accidents and incidents is a significant source of delay, particularly on roadways already experiencing congestion due to existing high peak period traffic volumes. Non

- recurring incidents can cause extensive and long lasting queues which in turn result in high emissions due to slow moving and idling vehicles. Programs such as the Emergency Service Patrols (ESP) and highway monitoring systems allow for quicker detection and response to incidents and accidents as they occur. By reducing t he duration of each event the extra emissions associated with the slow moving, backed

- up vehicles can be significantly reduced. **Methodology :**  The New Jersey Congestion Management System (NJCMS) contains a non

recurring congestion model that was used to tes t the impact of deploying Emergency Service Patrols along major roadways in the state that do not already have them. The roadways on which to implement new service patrols were determined by NJDOT staff after an extensive review . The non

- recurring model in the NJCMS was run both with and without the potential service patrols, and the total reduction in vehicle travel time was estimated. Not all the delay associated with an incident is idling, some is simply slower moving traffic that results when there i s a partial blockage or when traffic volumes are not very high. As a result, of the total non

- recurring delay estimated by the NJCMS, only 60% was assumed to be idling delay. This final estimate of idling delay was then multiplied by idling emission rate s developed from MOBILE 6.2 to estimate the total emission benefits associated with the expanded Emergency Service Patrol Program. A summary of the calculations and results is provided at the end of this document.**NEW JERSEY DEPARTMENT OF TRANSPORTATION Imple**  **mentation of Statewide Incident Managem ent/Service Patrols**  **RACM Analysis**
