| 摘 要： | 道路的交通事故诱发的原因多种多样,而同一段路上的交通事故的表现形式也很多。在选取事故形态表现形式和伤亡状况指标的基础上,采用系统聚类法中的类平均法对某段高速公路的事故状况进行分析,把具有某种共性的事故表现形式划归为一类,并对结果进行判别分析来检验聚类的效果,结果表明类别的划分突出特性,反应交通事故的主要事故形态,很大程度上反应事故原因,有利于相关部门采取相应的措施。

| Abstract: | Road traffic accidents are induced by different reasons.Forms of the road traffic accident at the same section are various.Based on choosing different accident forms and casualties indicators,clustering method is adopted to analyze accident status of a section.Some similar accident forms can be classified as a catergory.Results are analyzed to examine the effect of cluster.The results show that the category has its characteristics,and that forms of major traffic accidents reflect the reasons of the accident,which can help the related departments take corresponding measures. |
