信号交叉口行人过街速度的时空特征分析

Temporal and spatial characteristics analysis on pedestrian speed at signalized intersection

为了解信号交叉口不同空间及时间段的行人步行特征,对6个不同行人信号设置地点的交叉口的行人数据进行了采集,并采用统计分析方法分别对不同性别、年龄、结伴人数以及信号显示类型下的行人步行速度特征进行了分析。结果显示,行人性别对过街速度没有显著影响;行人年龄对过街速度有影响,青少年步行速度最高,老年人的步行速度最低;有无结伴行人对过街速度的影响不大;行人在无倒计时交叉口的过街速度显著高于有倒计时交叉路口的;行人在绿灯后期的过街速度显著高于绿灯前期的;而行人在道路前半幅的速度显著高于后半幅的。

In order to analyze the temporal and spatial characteristics of the pedestrian speed at the signalized intersection,the pedestrian data was collected at 6 different pedestrian signal setting sites in Chongqing. Using the statistical methods,the data wereanalyzed according to different gender,age,company and different signal. It was concluded that the gender has no impact on pedestrian crossing speed; that the age has a significant impact-the speed of the youth is the highest,and the elder＇s speed is the slowest; that the impact of company is the same as that of the gender; that the speed of the pedestrianat the signalized intersectionwith a countdown display is higher than that of the pedestrianat the intersection without it; thatthe pedestrian＇s speed is higher when he is walking towards the end ofgreenlight or in the first half of the roadway.
