Countdown-type traffic signals for vehicles that display the remaining green time and waiting red time have been installed positively in most Chinese cities. In this study, we analyze the behavior of vehicles under the countdown signal, especially the behavior of vehicles moving when the traffic signal changes from red to green. First, a variety of data were collected through observation of vehicles in Shenyang using video recording. Moreover, the distribution diagram and startup delay model were constructed according to processed data. The results show that countdown traffic signals would shorten startup delay, and work on the third car in the queue, but could also lead to a certain percentage of premature starts. On the whole, it appears that countdown signals can improve traffic efficiency and traffic safety at intersections.
