中文摘要：

建立了简练且有广泛应用性的无信号控制路段行人过街延误模型，定量的比较和分析了不同道路宽度和不同流量条件下一次过街方式和两次过街方式的行人延误，最后综合考虑行人过街的安全性、便捷性，机动车行驶效率和道路条件，给出了双向两车道和四车道时，两种过街方式的适用范围．研究成果可以应用于解析无信号控制行人过街设施的交通流特征和为最佳设置行人过街设施提供理论依据．

英文摘要：

This paper presents a universal and brief delay model for pedestrian crossing in no-signal controlled segment. Then a comparative study and quantitantive analysis are made of the pedestrian delay for single crossing and double crossing in different conditions such as various road widths and traffic flow. Finally the application of these two kinds of pedestrian crossing pattern for two-way two- lane and two-way four-lane are presented, with consideration of the security and convenience of pedes- trian, the efficiency of automobile and the condition of the road. This research can be applied to the analysis of the traffic character for pedestrain crossing and provide a basic theory for the improvement of pedestrian crossing facilities as well.
