Alternative Surveillance Concepts and Methods for Freeway Incident Management. Volume 2. Planning and Tradeoff Analyses for Low-Cost Alternatives.

摘要

Experience has shown that at traffic incident scenes,safety and operations can be improved if good on-site traffic management is used. Motorists lose about 750million vehicle-hours per year while waiting for incidents to be removed,and over 2million accidents per year occur on urban freeways alone. The research study identifies low-cost incident management systems for responding to freeway disturbances. Emphasis is placed on the development of pre-planned response techniques,candidate jurisdictional agreements,traffic operational procedures for incident sites,and overall improvement of freeway incident management. This volume of the report has been developed to present a planning methodology that can be used to evaluate existing incident management procedures and to estimate the potential effectiveness of low-cost techniques.
