无信号控制人行横道的宽度设置方法研究

Study on Width Setup Method of No-signal Pedestrian Crossing

从行人过街的统计特征出发,通过实测采集无信号控制人行过街的相关数据,依据临界可插车间隙理论,对无信号人行过街的临界可插间隙进行了预测,并通过比较得出正态分布更优的结论,然后文章利用迭代计算的方法对无信号人行横道宽度进行求解,并针对广州某具体交叉口进行了案例分析。研究成果可为城市无信号控制人行横道的设置提供参考。

According to the statistical characteristics of pedestrian crossing, through the measured collection of the relative data of no signal to control pedestrian crossing and based on the critical vehicle acceptance gap theory, the article predicts the critical acceptance gap of no-signal pedestrian crossing. After the comparison,the conclusion of more excellent normal distribution is achieved. The iterative computation method is used to solve the width of no-signal pedestrian crossing. The case of an intersection in Guangzhou is analyzed. The study result can be referred for the setup of no-signal pedestrian crossing.
