【摘要】：忍耐时间是分析电动自行车骑行者不安全过街行为的重要参数,是信号交叉口交通管控的重要约束条件.以红灯期间到达信号交叉口处违章过街的电动自行车为研究对象,应用多元线性回归分析和生存分析法中的Cox回归方法,统计分析骑行者在信号交叉口处的过街忍耐时间.该方法运用中国电信的"全球眼"网络视频监控技术,获取不同影响因素下宁波市电动自行车的实时视频数据,共采集了57 213个电动自行车过街忍耐时间样本.统计发现:电动自行车忍耐时间与5种影响因素存在强相关关系;7种影响因素对电动自行车忍耐时间的影响程度差异性较大,其中天气、人行横道长度和有无交警执法等3种因素的影响程度最大,出行时间和时段的影响最小;电动自行车过街忍耐时间的均值为48.600 s,标准偏差为300.341.
[Abstract]:Endurance time is an important parameter for analyzing the unsafe crossing behavior of electric cyclists and an important constraint for traffic control at signalized intersections. Taking the electric bicycle at the signal intersection during the red light as the research object, the multivariate linear regression analysis and the Cox regression method in the survival analysis were used to analyze the cross street endurance time of the cyclists at the signalized intersection. This method uses China Telecom's "Global Eye" network video surveillance technology to obtain real-time video data of electric bicycle in Ningbo under different influence factors. A total of 57,213 samples of endurance time of electric bicycle crossing the street are collected. Statistics show that there is a strong correlation between endurance time of electric bicycle and five influencing factors. The influence degree of seven factors on endurance time of electric bicycle is quite different, among which the weather, The length of crosswalk and the law enforcement of traffic police have the biggest influence, the travel time and time are the least, the mean time of electric bicycle crossing the street is 48.600 s, the standard deviation is 300.341.
