摘　　要：通过对城市道路无信号控制交叉口行人穿越特性的分析,总结出反映行人穿越效率的3个主要效率指标。对现有行人临界穿越间隙的计算公式进行合理、全面的修正,得出将总的行人平均延误30 s作为行人控制信号的1个设置标准。同时,采用行人可穿越机会数(CO)和当量行人流量(EAU)指标来建立模型,作出基于行人特性的信号设置依据图形,作为行人控制信号的另一个设置标准。最后对按钮式行人信号灯的基本原理和适用条件作了简要分析。In this paper,research was conducted on the pedestrian crossing characteristics at unsignalized intersections at urban roads.Three practical indicators were concluded to reflect pedestrian crossing efficiency,of which we lay emphasis on the critical crossing gap of pedestrian and gave a more reasonable and and comprehensive formula of the critical crossing gap of pedestrian.Then we obtained the total average delay of 30 seconds,as a setting standard of pedestrian control signals.Meanwhile,we used the number of crossing opportunity and equivalent pedestrian volume to build models and made a signal setting basis graph based on pedestrian characteristics as another setting standard.In the end,we made the summary analysis of basic principle and suitable conditions of the pedestrian traffic signal with buttons.
