北京市信号交叉口行人过街忍耐时间研究

行人交通是信号交叉口交通的重要组成部分.目前信号交叉口的规划设计优先考虑机动车效率,为了保障机动车的通行效率,北京市多数行人过街环境遭到破坏,"中国式过马路"应运而生.结合当前北京市交通的特点,以红灯期间到达信号交叉口人行横道等待区的行人为研究对象,运用视频调查和人工调查相结合的方法获取北京市不同影响因素下行人过街忍耐时间的基础数据,采集了9554个行人过街忍耐时间样本.建立信号交叉口行人过街忍耐时间的 Cox 风险回归模型,结果表明信号交叉口行人过街的最大忍耐时间是52.88 s,信号交叉口行人过街忍耐时间与温度、性别、年龄、出行时间、红灯时长、单位机动车流量、人行横道长度等影响因素有关,用地性质对信号交叉口行人过街忍耐时间的影响不显著. 

A Study of Tolerant Waiting Time of Pedestrians at Signalized Intersections in Beijing

Pedestrians are an important part of traffic at the signalized intersections.At present,the planning and design of the signalized intersections give priority to efficiency of the vehicles.In order to ensure the efficiency of the vehi-cles,many pedestrians crossing environments have been destroyed in Beijing."Chinese style of pedestrian crossing" was invented.Based on the characteristics of the current traffic in Beijing,this study focuses on the pedestrians who arrive at the signalized intersection crosswalk waiting area during the red light.A total of 9 554 pedestrians'waiting time were col-lected by both video survey and manual survey under the different conditions.This study develops a Cox hazard-based model of pedestrians'tolerant waiting time at signalized intersections.The result shows that the maximum tolerant waiting time of pedestrians is 52.88 s.The temperature,gender,age,travel time,red light time,traffic volume,length of cross-walks have great impacts on the pedestrians'tolerant waiting time,however land usage have no significant impacts on it.
