TRAFFIC LIGHTS: PILOT STUDY: AMBER/RED FLASHING PHASE (DURBAN)
This report covers an experiment carried out in Durban from November 1979 to November 1980, to determine the effect of a flashing amber and red phase on traffic safety. Accident data revealed no significant statistical differences between the before and after studies. Opinion surveys revealed that the meaning of the flashing signal was not fully understood. It was observed that more than 50 percent of motor vehicle drivers crossed the intersection without stopping when the red flashing phase was operating. In accordance with report rt/20/81, it was found that vehicle stops and idling time decreased. (TRRL)
