摘要：AbstractThe study aims to explore the drivers’ reaction time influenced by the red-light timing at urban signalized intersections. The red-light timing ranges from 40seconds, 60s, 80s, 100s, and 120s. E-prime is used to simulate the signalized intersections and measure the drivers’ reaction time to the onset of green-light. 30 undergraduate drivers are involved and the data is analyzed in SPSS 17.0. The results show that 80seconds is the maximum timing for waiting for the red light as compared to other four timings in the way of shortest reaction time to the onset of green light. It is therefore suspected that the span of 80seconds is the cut-off timing for the red-light waiting at the intersections.
