| 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。

| Abstract: | 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 obtained.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 conclu... |
