交通事故对城市道路交通能力影响的研究

The study of influence of traffic accidents about traffic capacity of city road

随着人民生活水平的不断提高,城市交通问题也日趋凸显,特别是交通事故引发的拥堵。本文依据某十字路口两个时段一般交通事故对实际车辆通行情况进行建模分析,定量研究三车道交通事故对道路畅通的影响,得出一般交通事故发生的周期性规律:事故m到红绿灯的距离对交通恢复畅通有直接关系,排队长度和排队时长是影响道路交通的最主要因素,而排队时长对道路通行的影响更大;外车道发生事故会依次影响中间车道和内车道车辆行驶;事故的解决周期一般在半个小时。

With the increasing improvement of people's living standards,urban traffic problems have become increasingly prominent,especially the congestion caused by traffic accidents.Based on the two-period traffic accidents at an intersection,analyzing the actual traffic and Quantitatively studying the impact of three-lane traffic accidents.The results show that:there is directly relation between the traffic capacity of city road and the distance from the accident point to the traffic light;when accidents is happened in the outer lane,firstly it will affect the middle lane and then effect the inner lane;the resolution of accident is generally spend half an hour.
