摘要
行人交通是城市交通体系中非常重要的部分,在城市交通出行中占有很大比例。然而,中国20多年的快速城镇化过程中,往往更多关注高速增长的机动化交通,行人交通的地位越来越被边缘化。重点对中国城市道路交叉口行人与机动车的冲突问题进行了分析,指出行人过街设施在规划设计及信号控制方面,以及现行法律法规相关规定的不足。针对行人清空灯色的设置,提出中国应采用红闪作为行人清空信号的建议。最后,围绕行人与右转、左转机动车的冲突问题,提出了若干在一定条件下可能有效的信号控制策略。
Pedestrian traffic is an important component of urban transportation system,accounting for a large proportion of total urban trips.However,during the rapid motorization and urbanization over the past20years in China,more attention has been paid on motorized vehicles,while pedestrians'requirements are quite often neglected.This paper analyzes the pedestrian-vehicle conflicts at urban intersections,and points out the deficiencies of pedestrian crossing facilities in planning,design,signal control,as well as related traffic laws and regulations.In terms of pedestrian clearance signal,this paper proposes to use flashing red in China.Finally,the paper proposes several signal control strategies that may be effective under certain conditions to reduce the conflicts between pedestrians and right-and left-turn vehicles.
