不同类型人行信号灯对过街行人的安全影响研究

随着对行人交通关注的加强,寻求更安全、更便利的行人交通设施越来越受到重视.鉴于此,首先介绍我国一般交叉口常用的静态人行信号灯、动态人行信号灯和倒计时人行信号灯三种信号灯的特点；然后分析人行信号灯对行人过街安全的影响,利用问卷调查法和摄像调查法,定性研究不同类型人行信号灯对行人过街心理和行为的影响,定量研究不同类型人行信号灯对行人过街守法率、过街速度和行人与右转机动车的交通冲突数的影响,对科学设置交通设施,减少交通事故,保证人、车安全具有重要的意义.

Safety Study of Pedestrians Crossing Street with Different Types of Pedestrian Lights

With the strengthening of attention to the pedestrian traffic, seeking more secure and conve- nient pedestrian traffic facilities has been paid more and more attention to. This paper first introduced the features of three commonly used signals at general intersection in China, including static pedestrian lights, dynamic pedestrian lights and countdown pedestrian lights. Secondly, it analyzed the influence of different pedestrian lights on the safety of pedestrians crossing the street, using the method of question- naire and video investigation, qualitatively studied the influence of different types of pedestrian signal lights on pedestrians＇ psychology and behavior, and quantitatively studied the influence of different types of pedestrian signal lights on pedestrians＇ law-abiding rate, crossing speed and traffic collisions between pedestrian and right-turn motor vehicle. It has important significance on setting traffic facilities, reducing the number of traffic accidents and ensuring the safety of pedestrian and cars.
