道路交通次级冲突的研究分析

介绍了次级冲突的定义和分类,分析了次级冲突的产生、传播和消散的过程,把次级冲突的传递看做是一种波的传播,主要研究了首部车辆和次级冲突车辆之间的间距和速度等状态。当加速波大于减速波时,该次级冲突的影响就会消散;并提出了一种基于交通波传递和消散的计算方法,用于计算次级冲突的影响车辆数,在此基础上采用调查方法来实现这一计算方法。同时该影响范围可以为交通冲突的严重性的判断提供一个科学定量的参考依据。

The Research of Secondary Traffic Conflict of Roadway

This paper describes the definition and classification of secondary traffic conflict generally,analysis the process of the generation,transmission and dissipation of the secondary.It takes the transmission of the secondary traffic conflict as a propagation of wave,mainly researches the state of distance and speed between the first vehicle and the secondary traffic conflict vehicle.When the speed of the acceleration wave is faster than deceleration wave,the effects of the secondary traffic conflict will be dissipated.And the article presents a method used to calculate the number of vehicles in the scope of secondary conflict based on the propagation and dissipation of the traffic wave.Based on this survey with a simple way to achieve this calculation.A simple survey way can be achieved this goal based on this theory.Meanwhile,the affected area can provide a scientific qualitative reference to determine the seriousness of the conflict of traffic.
