Book Description
Freeway incident management has become an important issue in departments of transportation nationwide. With many of the nation's roadways operating very close to capacity under the best of conditions, the need to reduce the impact of incident-related congestion has become critical. One way to achieve this reduction is to improve the management of traffic after an incident has occurred, including the use of traffic diversion strategies. Very often, however, diversion strategies are employed without proper consideration given to the effect of such a strategy on the alternate route, which in many cases is congested prior to the addition of diverted traffic. Careful analysis of diversion strategies, which includes examination of the operational characteristics of both the freeway and alternate routes, can lead to much more efficient and effective strategies. This project establishes a methodology for analyzing diversion strategies using CORSIM, a microscopic simulation model developed by the Federal Highway Administration capable of simultaneously analyzing freeway and arterial roadways. The model process for incident specification and simulation was tested and applied to several case studies. The results of the study show that the model is a valuable tool in analyzing diversion strategies; the critical freeway volume at which diversion becomes advantageous can be determined, as can bottleneck locations on the alternate routes. Signal timing adjustments can be tested and fine-tuned to achieve the ideal maximum flow along the diversion route.

Book Description
This synthesis report will be of interest to officials of municipal, regional, and statewide transportation and law enforcement agencies who are responsible for roadway incident diversion practices. It will also be of interest to others who interact with these agencies to achieve a better understanding of the processes, barriers, and technologies associated with alternate route plan development and deployment. This report presents state-of-the-practice information about the development and implementation of roadway incident diversion practices. It documents specific trends in the practice, and in examining individual practices, identifies unique plans, processes, and technologies from which other agencies may find useful applications. This TRB report addresses a broad list of topics associated with roadway incident diversion and profiles successful incident diversion practices, as reported by surveyed agencies. In particular, it focuses concern on alternate route plans for random incidents, those resulting in nonrecurring congestion.

Book Description
This report presents an analysis of freeway incidents on the Salt Lake Valley freeway network. Different types of incidents at the most common/difficult locations are analyzed through traffic microsimulation using VISSIM simulation software. The analysis focuses on incident induced freeway delays, but it also looks into other parameters, such as vehicle throughput, travel times and network-wide delays. The goal of this project is to develop a set of incident management strategies that would help TOC operators to make decisions that will optimize their response in terms of time and resulted delay, and minimize users' cost due to delay on the freeway network.
