Description:
For accident prevention, as a Traffic Demand Management (TDM) strategy, amber lights are flashed at signalised intersections signalling drivers to drive with caution. Flashing amber light is used mostly during night hours with very a low incidence of traffic or when signal cycle timing is dysfunctional. However, this precautionary action has not eliminated intersection collisions. During off-peak hours, many intersection collisions have been reported. The occurrence of accidents in signalised intersections during off-peak hours is due to incompatibility between the expected and actual reactions of drivers to flashing amber lights or the complete ignorance of drivers. Therefore, this study focuses on how drivers psychologically react to flashing amber lights through an assessment of speed levels of vehicles passing an intersection.
