Driver Behavior During Yellow Change Interval

When drivers are approaching a signalized intersection at the onset of a yellow change interval, they must decide whether to stop or cross the intersection. This can be a difficult decision when the vehicle is located within the dilemma zone and the result is sometimes a rear-end crash due to a sudden stop. This paper presented a new pavement-marking countermeasure which purpose is to reduce the red-light running rate and assist motorists with stop/go decisions. To test the effectiveness of the pavement-marking countermeasure, this paper presented a UCF driving simulator experiment designed to collect information concerning drivers’ behavior during yellow change interval at intersections with 30 mph and 45 mph speed limits, and to compare the differences of drivers’ behavior between scenarios with the marking and scenarios without the marking.
