摘　　要：根据道路交通管理部门基于事故数据库挖掘事故成因的需要,将交通事故属性划分为两个层次,应用粗糙集理论,分步给出了"人、车、路、环"四要素及各自包含属性对交通事故重要程度的计算方法。实例分析和t检验结果表明了方法的有效性。To meet the demands of accident causes mining of road traffic management departs based on accidents database, traffic accidents attribute are divided into two layers. The top layer is consist of four macro attributes including human, vehicle, road, environment, while the bottom layer includes several attributes which belong to each of four macro attributes. To apply the rough set theory, the calculate method of significant degree which is the influencing degree of each layer＇s attribute to accident severity is given separately. The case study and result oft test of significance show that the method is validity.
