EVALUATION OF A PROTOTYPE WARNING SYSTEM FOR URBAN FREEWAYS

This paper evaluates a prototype real-time system that warns approaching motorists of stoppages downstream of cresting vertical curves. Before and after studies were conducted to measure primary and secondary accidents. A questionnaire survey was administered to obtain motorist reactions. The study results revealed that the warning system is cost effective. Both primary and secondary accidents were reduced. The results of the questionnaire study indicated that motorists believed that the system was useful, that the warning sign was readily noticed, and that the message was generally understandable and appropriate to traffic conditions.
