Alternative Surveillance Concepts and Methods for Freeway Incident Management. Volume 4. Guidelines for Specific 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 give assistance to police,highway,and traffic engineering planners in defining and establishing one or more low cost techniques (alternatives) by providing guidelines for their implementation.
