摘　　要：归纳总结了现有事故成因分析方法的特点和适用条件,提出了包括人、车、路和环境的山区高速公路交通事故影响因素,分析了各因素间的交互作用。提出了基于FCM聚类的山区高速公路事故多发点成因分析方法,并以京珠高速公路为例进行了验证。结果表明,该方法目标函数的聚类方法设计简单、解决问题范围广、易于计算机实现;山区高速公路最主要的事故因素是车辆追尾和刹车失灵。The characteristics and applicable conditions of the cause analysis are summarized. The traffic crash factors of mountain expressway, including people, vehicles, roads and environmental, are presented. And the interaction of the factors is analyzed. A method of crash-prone points causes analysis of mountain expressway based on FCM is proposed, and a case of Beijing-Zhuhai Expressway is taken to verify the method. The results show that the method is simple, widely applicable and easy to computer im- plementation; the main crash factors of mountain expressway are rear end collision and brake failure.
