无信号控制人行横道处行人过街特性探析

行人是交通环境中的"弱势群体",尤其是在无信号控制人行横道处,研究行人交通特性是提出改善行人安全措施的前提。本文初步对无信号控制人行横道处人车干扰运行和行人过街运动特性进行定性分析,并选取长春市南湖大路上具有代表性的无信号控制人行横道进行实地观察和试验,定量分析行人到达人行横道规律和行人过街速度特性,其中重点分析年龄、性别和人群中行人数量对行人过街速度的影响。按照年龄将行人分为中、青年人,老人,儿童;按照性别将行人分为男性行人和女性行人;人群中行人数量主要选取1,2,3及4人以上进行研究。这些数据和分析结论对下一步针对实地情况提出改善行人交通安全的方案提供了基本的理论依据。

Study on Characteristics of Pedestrian Crossing Unsignalized Crosswalks

Pedestrian is"vulnerable group"in traffic environment,especially at unsignalized crosswalk.Research on pedestrian is es- sential for pedestrian safety improvement.The characteristics of pedestrian movement and interference between pedestrian and vehicles are qualitatively analyzed.Observing and testing at unsignalized crosswalk on representative Nanhu street of Changchun City,the regularity of arrival at crosswalk and the characteristics of speed are quantitatively analyzed,in which focus on influence on speed from age,sex and amount of pedestrian in each pedestrian group.Pedestrians are classified to middle and young people,old people and children by age; Pedestrian are classified to male and female by sex.1 to 4 persons above are chosen according to the amount of pedestrians in each pedes- trian group.The data and analysis provide elementary theoretical reference for next scheme to improve pedestrian traffic safety.
