摘要
在信号灯设置中,黄灯起到过渡的作用.理解黄灯期间的驾驶行为对于黄灯期间的安全保护,以及黄灯时长的设置具有重要意义.对比了国内外相关研究的数据获取方法、分析方法,对我国城市道路中2种常见的信号控制的十字交叉口与路段人行横道进行实地调查,利用视频拍摄的方法获取实验数据,分别分析车辆在黄灯期间的驾驶行为.根据车辆行驶速度、与停车线的距离这2个因素,以Spss为分析工具,利用二元Logistic模型,建立了车辆在黄灯期间的驾驶行为模型.其中基于时间变量建立的模型精度为15.9％,由模型得出其犹豫区的时间分布为1.89～4.86 s.
The yellow light acts as an early warming for the drivers. Understanding the drivers＇ responsive behav- iors to yellow light is significant for the safety during the yellow light and the length setting of yellow light. At first, the data for collection and analysis between domestic and foreign revenant researches are compared. Two kinds of typical in- tersections in China, cross intersections and the intersections only for pedestrian crossing, are investigated. Based on the data obtained from video recording, the driver behaviors in these two types of intersections are analyzed respectively. By considering the two factors, i.e. speed and distance to the stop line at the start of the yellow light, Spss software is used to build a binary Logistic model. The precision of the model based on time variable is 15.9%, and the time distribution in the indecision zone is 1.89 s～4.86 s.
