信号交叉口行人过街速度分析

Crossing speed analysis for pedestrian at signalized intersection

通过对哈尔滨市11个交叉口中的42条人行横道进行调查及数据的分析处理,得到总体行人平均过街速度为1.47m/s、85％位速度为1.74 m/s、15％位速度为1.19 m/s。分析了行人年龄、性别、人行横道长度、过街人数量、绿灯时间等对行人过街速度的影响。结果表明,信号交叉口的设计中,应使用15％位过街速度,可满足85％以上行人的行走要求;在老年人经常出现的地区,设计速度应为老年人的15％位速度,即1.07m/s。

Pedestrian crossing speed at signalized intersection is an important parameter in traffic safety analysis and traffic signal design. The surveying and analyzing 42 crosswalks of 11 intersections of Harbin comes to a conclusion that, as a whole, average pedestrian crossing speed is 1.47 m/s, for 85% of pedestrians, the crossing speed is 1.74 m/s and 15% speed is 1.19 m/s. The impacts of pedestrian age and sex, foot-crossing length, number of crossing pedestrians and green time on pedestrian crossing speed are analyzed. It is then pointed out that when designing signal intersection, 15% speed which is 1.19 m/s should be used, and which satisfies demands of more than 85% pedestrian. In the area where the elderly often go to, the design speed should be 15% speed of the elderly, that is 1.07 m/s.
