摘　　要：交通延误是评价城市信控道路交叉口服务水平和车辆通行效率的一个重要指标.未设置右转专用相位的信号交叉口右转车辆与行人的冲突会引起右转车辆的延误.本文从微观角度分析了在未设置右转专用相位的信号道路交叉口右转车辆穿越过街行人流的过程,考虑了右转车辆抢行状况及过街行人不同过街状态,建立并验证了未设置右转专用相位信控道路交叉口右转车辆穿越过街行人流的车均交通延误模型.The traffic delay is an important index to evaluate the service levels and the operation efficiency at a signalized intersection.The conflict between right turning vehicles and pedestrians at the signalized intersection where being no exclusive right-turn traffic phase will lead to traffic delay.This paper analyzed the process of the right-turning vehicles traversing pedestrians crossing at a signalized intersection where there is no right turn signal from microscopic perspective,considering the right-turning vehicles which traverse the pedestrian crossing area forcibly and the difference of states of pedestrians crossing at a signalized intersection,set up and verify an average traffic delay of right-turning vehicles traversing pedestrians crossing area at a signalized intersection where there is no right turn signal.
