The effects of green signal countdown display (GSCD) on driver behavior were researched from two aspects: space and time. This study aimed to compare and analyze driving behavior affected by using GSCD at signalized intersections using the approach of field investigation for acquiring data. The research results showed that the average speed of crossing the stop line was higher at intersections with GSCD, but the proportion of high speed was relatively reduced, which indicated that the GSCD was not only good for traffic efficiency but also for traffic safety. The reason was that the driver behavior was more conservative at intersections with GSCD, and drivers tended to maintain high speeds at intersections without GSCD. In addition, signal countdown displays can reduce start-up lost time and unify driver behavior to ensure that vehicles leave the intersection at a steady speed.
