摘　　要：简述了各类道路安全评价方法,对比分析了可拓评价方法的优点,为了提高道路安全评价的准确性,以可拓学的理论和评价分析方法为基础,利用道路工程项目定性等级和影响因子构建经典域物元和节域物元,采用物元理论、可拓集合论和关联函数完成相应的物元模型计算。结合某高速公路工程实例进行分析和计算,结果与实际情况符合良好,适用于道路工程项目安全性评价。Various methods of road safety evaluation were explained. The advantages of the extensional evaluation method were focused, which is a newly adopted method for road safety. Furthermore, an evaluation matter-element model of road safety was established based on the extension theory. The functions of the extensional evaluation method were ob- tained. Finally, the result of the extensional evaluation method was compared with those of other methods based on the existing road accidents data of a certain highway. It concludes that the results of the extensional evaluation method can provide a scientific basis for road safety management.
