城市道路平面交叉口交通安全评价

Safety Evaluation of Urban Road Intersection

城市道路平面交叉口因其交通组成、交通特性非常复杂,是交通事故多发点之一。鉴于此,针对传统的交叉口安全评价问题,引入交通冲突技术,选取合适的评价指标建立基于交通冲突技术的平面交叉口交通安全评价方法,并应用该评价方法对某交叉口的交通安全状况进行评价分析。

Urban road intersection is one of the accident-prone spots due to its complicated traffic compo- sition and traffic characteristics. Because of the shortcomings of the traditional intersection safety evaluation methods, by selecting appropriate evaluation indexes, method which makes use of the traffic conflict techniques to assess the intersection safety evaluation was proposed in the paper. Then the established evaluation method was used to assess the traffic safety situation of one actual intersection.
