Abstract

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. 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.
