Field and Driving Simulator Validations of System for Warning Potential Victims of Red-Light Violators
Two experiments were conducted to provide partial validation for the concept of a system to warn the potential victims of red-light violators. As conceived, the warning system would entail sensors to detect vehicles that are approaching red traffic signals and would be unlikely or incapable of stopping. The system would then use flashing signs and lights to warn drivers on the intersection approaches that are in the green phase. Several human factors issues are identified that would need to be addressed before such a system could be deployed. The present experiments addressed one of these issues- would a sufficient number of drivers respond to such a warning in a way that would avoid collision with a red-light violator? The results suggest that the majority of drivers will brake sharply in response to a conspicuous warning, at least for the case where no other vehicles are following the potential victim. Comparisons between field test and driving simulator response measures are discussed, as are the implications for further research.
