| 摘 要： | 人行横道通行能力是确定行人过街设施的基础参数。通过分析信号交叉口处人行横道混合交通特征,提出了一定周期时长和单位人行横道宽度的人行横道绿灯时间内的实际通行能力计算公式;以可接受间隙理论为基础,利用概率论的方法,推导出了无信号交叉口处人行横道的通行能力计算公式,并通过实例验算,具有一定的实用价值。

| Abstract: | Capacity of pedestrian crosswalk is the basic parameter of the pedestrian crossing facilities.Based on the analysis of the mixed traffic characteristics of pedestrian crossing in signal intersection,this paper put forward the calculation formula of pedestrian crossing＇s actual travelling capability in the green time,corresponding to the certain period of long and unit width.Based on the gap acceptance theory and the method of probability theory,the paper deduced the calculation formula of pedestrian crossing＇s travelling capability at un-signalized intersection.Examples show that it is valuable in practice. |
