A Driving Simulator Evaluation of Active Warning Signs

Abstract

This paper describes a driving simulator experimental evaluation of active warning signs designed to portray potential conflicts at unsignalized intersections. The signs are designed to reduce accidents due to crossing path and left turn movements, and are intended to be less expensive than signals and more effective than conventional signs. Diamond and rectangular shapes with a range of symbology conditions were tested, including arrow and car icons that were presented in both static and flashing or animated conditions.
