Abstract:This study developed a working database for calculating incident rates and related delay measures, which contains incident related data collected from various data sources, such as the New Jersey Department of Transportation (NJDOT) Crash Records, Traffic Operation Center (TOC) incident data, TOC Emergency Service Patrol (ESP) data, and New Jersey Turnpike and Garden State Parkway incident data. In order to improve the output accuracy of non-recurring delay estimated by the New Jersey Congestion Management System (NJCMS), there is a need to develop the NJ specific incident rates, response times, and clearance times for both peak and off-peak periods. This study determined whether new data in the form of actual field observations of incidents (from the beginning to the end of an incident) will be reasonable and useful to supplement and tie together the existing data. An assessment of cost and benefit analysis was conducted, while a list of recommendations were provided at the end of this report.
