北京市信号交叉口行人过街忍耐时间研究

为了保障信号交叉口机动车的通行效率，多数行人过街环境遭到破坏，“中国 式过马路”应运而生.通过对北京市信号交叉口行人过街忍耐时间的研究，在保障行人过 街安全的情况下对提高交叉口运行效率，推进“公平优先，保障效率”战略的实施，促进城 市交通系统高效运转具有重要的意义.本文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处违章过街的行人为研究对象，运用视频调查和人工调查相 结合的方法，采集了9 554 个行人过街忍耐时间样本.建立了信号交叉口行人过街忍耐时 间的韦布尔参数分布模型.结果表明，信号交叉口行人过街忍耐时间与环境因素、行人特 性、出行时间、交通状况，以及道路环境等影响因素有关.

Endurance Time of Pedestrians Crossing at Signalized Intersection of Beijing

In order to ensure the efficiency of the vehicles at signalized intersection, many pedestrians crossing environments have been destroyed in Beijing, "Chinese style of crossing road" came into being. Based on the research on the endurance time of pedestrians crossing at signalized intersection of Beijing can ensure the safety of the pedestrian crossing and has a great significance on improving the efficiency. Moreover, it has important practical significance on promoting the strategy of "equity priority and give consideration to efficiency" and improving the efficiency of urban traffic system. According to the characteristics of the current traffic of Beijing, the paper focuses on the pedestrians crossing illegally who arrive at the signalized intersection crosswalk waiting area during the red light. The paper uses both video survey and manual survey to collect 9,554 samples of endurance time. The paper establishes Weibull distribution parameter model of pedestrians crossing endurance time at signalized intersection. The results show that environmental factors, pedestrians characteristics, travel time, traffic conditions and road environment have great influence on the pedestrians crossing endurance time.
