首先,通过对常用事故多发点鉴别及其成因分析方法的评述和对比,论证了研究基于交通冲突的事故多发点鉴别方法的必要性。其次,通过研究交通流基本模型,采用Logit模型描述驾驶员驾驶行为,为后续研究做基础。最后,分别对同向冲突、穿越冲突、对向左转冲突和二次冲突分别做研究,得出了每类冲突的计算模型。基于此,提出了公路平面交叉口事故多发点的鉴别方法。
First of all, through the commentary and comparison of the methods to identify and analyze the frequently occurred accidents of common accidents, the necessity of studying the method of discriminating accidental multiple points based on traffic conflicts is demonstrated. Secondly, by studying the basic model of traffic flow and using Logit model to describe the driver’s driving behavior, it is the basis of subsequent research. Finally, the paper separately studies the same-conflict, cross-conflict, left-turn conflict and secondary conflict respectively, and obtains the calculation model of each type of conflict. Based on this, a method of discriminating multiple points of intersection at highway plane intersections is proposed.
