中文摘要：

根据行人流随机消散和集中消散的不同特征,应用随机分布理论推导出右转车辆穿越行人流的两类延误模型,分析了车辆穿越过程的延误特征。应用Vissim仿真软件对右转车辆穿越行人流进行模拟,并对比了仿真延误与模型计算延误。分析结果表明：当行人集中消散时长为10 s,随机消散时长为15 s,各排行人的时距为5 s,行人流量达到1 100人.h-1时,才产生0.2 s的误差,可见,该延误模型可行。

英文摘要：

Based on the different characteristics of stochastic and congestion dispersing processes for pedestrian flows,two kinds of right-turning vehicle＇s delay models were defined by using stochastic distribution theory,and the delay characteristics during vehicle crossing pedestrian flow were analyzed.The crossing process of right-turning vehicle was simulated by using Vissim software,and the simulation delay value was compared with that of the delay models.Analysis result shows that when the length of pedestrian congestion dispersing time is 10 s,the length of pedestrian stochastic dispersing time is 15 s,each interval between pedestrians is 5 s,and pedestrian flow reaches 1 100 persons per hour,the deviation of the delay models is only 0.2 s,so the models are feasible.1 tab,11 figs,15 refs.
