EVALUATION OF A PROTOTYPE SAFETY WARNING SYSTEM ON THE GULF FREEWAY

This study is concerned with the evaluation of a prototype real-time system that warns approaching motorists of stoppages downstream of crest type vertical curves. Before and after studies were conducted to measure speed changes and 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 system did not create any adverse traffic operational conditions. The results of the questionnaire study indicate the motorists believed the system to be useful, the warning sign was readily noticed, and the message was generally understood and appropriate to traffic conditions. /FHWA/
