城市干道无信号控制人行横道行人过街特性分析

Characteristic analysis of pedestrian crossing unsignalized crosswalks at urban arteries

对城市干道无信号控制人行横道行人过街特性进行了分析,在对行人过街定性分析的基础上总结出反映行人过街效率的6个具体指标,以某市典型无信号控制人行横道为实例进行了交通调查,测算了行人过街效率指标的实际值.通过对指标值的分析,找出了观测路段交通秩序混乱的原因,提出了具体的改进建议.

Research was conducted on pedestrian characteristics at unsignalized crosswalks at urban arteries, which pedestrians frequently use on trips. Six practical indicators were concluded to reflect pedestrian crossing efficiency, based on concrete analysis of pedestrian behavior. Datas were obtained from observing typical unsignalized crosswalks by field survey in Changchun City, and the values of pedestrian crossing efficiency indicators were calculated. The reason that caused disorder in the observed mid-blocks was clarified by analyzing the indicator value, and improvement was proposed.
