Effects of the Countdown Lights on the Capacity of Signal Crossing

Real-time traffic signal countdowns display the time remaining on the traffic signals that can alert drivers and pedestrians under a phase start time, so that drivers and pedestrians can make the appropriate response with the upcoming phase change, with reasonable and efficient use of time waiting for the green light to display the startup phase. To study the impact of the countdown lights on signalized crossing capacity to Beijing’s West Fourth Ring Road crossing for a typical object, both the countdown and the no-countdown crossing signals were observed. The T-test method using statistical analysis found similar environmental signals traffic crossing. There is a countdown display compared to the saturation time headway and lost time has been reduced crossing traffic crossing with no-countdown display capacity and traffic safety increased.
