摘 要：通过对城市无信号控制路段人行横道的机动车和非机动车的过街交通特征的分析，提出非机动车过街的可穿越间隙计算方法，分别对非机动车过街一次穿越1条车道和一次穿越多条车道出现可穿越间隙下的2种情况进行分析，并运用所提可穿越间隙的计算方法，推算出非机动车过街平均延误。经过实地调查及计算结果分析，验证非机动车过街平均延误计算方法的科学性。并将人行横道非机动车和行人的过街延误进行比较。结果表明，非机动车过街延误是人行横道处过街总延误的重要组成部分。

Abstract:By analyzing the moving feature of crossing of motor vehicles and non-motor vehicles in non-signalized segment crosswalks, the calculation method of acceptance gap through which non-motor vehicles may cross motor vehicle flow was proposed, and the average delays under two different conditions were analyzed further: one condition was that non-motor vehicle crossed a lane once, and the other one was that non-motor vehicle crossed more than one lane once. After field survey and calculation, the accuracy of the proposed calculation method was verified. The delay of crossing the road of non-motor vehicles was compared with that of pedestrian. The results show that the delay of non-motor vehicles is a very important component of the total delay of crossing.

Key words:non-motor vehicles crossing; crosswalks; non-signalized controlled segment; acceptance gap; delay
