交通冲突伤害在无控制交叉口安全性评价中的应用

Safety Evaluation of Traffic Conflicts Injury on an Uncontrolled Intersection

无控制交叉口由于其形式简单、组织方便,已成为目前最基本的交叉形式之一。但其交通约束性差,在机动车数量急剧增加的今天,更成为交通事故的多发地点。加强无控制交叉口安全隐患的排查,提高其安全性成为社会关注的焦点。本文通过对无控制交叉口的车辆运行状态进行分析,建立基于冲突伤害的安全评价指标,从而确立无控制交叉口的安全形势。

An uncontrolled Intersection is one of the most basic cross types due to its simple form and convenient organization. But as the bad constraint of operation, traffic accidents happen frequently at uncontrolled intersections. So strengthening the inspection of hidden danger and enhancing the security has become the focus in society. According to the analysis of vehicle operation estate at uncontrolled intersection, a new safety evaluation index was established based on conflicts injury so as to determine the security situation at uncontrolled intersection.
