Changes in Driver Behavior Resulting from Pedestrian Countdown Signals


This paper explores the effects that pedestrian countdown signals have on driver behavior. Observations of two intersections, one with pedestrian signals and one without, were made focusing specifically on driver behavior during the amber and red phases. It was found that drivers at the pedestrian countdown intersection were less likely to enter the intersection at the end of the amber phase than those at the traditional pedestrian signal intersection. It was also found that drivers at the intersections with traditional pedestrian signals exhibited different stopping behavior near the intersection, possibly related to sudden braking. This was determined by measuring the rate of vehicles stopping at each intersection per cycle.
