METHODOLOGY FOR ESTIMATING THE IMPACTS OF INCIDENT MANAGEMENT MEASURES

Freeway incident management systems (FIMS) facilitate the quick removal of incidents to reduce congestion delay and other adverse impacts on urban freeways, and to provide travel information to motorists. The effectiveness of such systems depends on the freeway design characteristics, traffic volumes and incident frequency and patterns. Traditional methods of evaluating the benefits provided by FIMS rely on theoretical calculations. The authors have determined that these theoretical measures often result in an overestimation of the benefits. They present an alternate methodology for determining the benefits of FIMS based on extensive field data involving probe vehicles, incident observations, and loop detectors. The methodology has been applied to determine the expected benefit to cost ratio of freeway service patrols (FSP) at a San Francisco Bay Area freeway section.
