为深入了解引发我国无信号控制公路交叉口行人死亡事故的根本原因,首先采用描述统计方法,分析事故在道路交通环境、车辆、行人和驾驶员等4方面17个因素上的分布特征。然后采用驾驶可靠性和失误分析方法(DREAM),分析摩托车直行、汽车直行和汽车左转3类事故的机理,归纳事故的主要影响因素。最后,根据事故特征和机理,分析总结目前在事故预防上存在的主要问题,提出解决思路。结果表明,安全设施缺乏、驾驶员培训不足和行人安全意识差是目前威胁我国无信号控制公路交叉口行人安全的3个主要问题。
In order to understand deeply the root causes of pedestrian fatal accidents in highway intersection caused by no signal in our country, firstly, the descriptive statistics method is used to analyze the distribution characteristics of the 17 factors in 4 aspects of road traffic environment, vehicles, pedestrians and pilots. Then using the driving reliability and error analysis method (DREAM), this paper analyzes the mechanism of three types of accidents such as straight-ahead motorcycle, straight-ahead motor vehicle and left-turn vehicle, and summarizes the main influencing factors of the accident. Finally, according to the characteristics and mechanism of the accident, this paper analyzes and summarizes the main problems existing in accident prevention and puts forward some solutions. The results show that the lack of safety facilities, lack of driver training and poor pedestrian safety awareness are the three main problems that threaten our pedestrian safety without signal control at the intersection.
