摘　　要：构建一级公路设计安全性评价的量化值,建立了一级公路安全性评价的指标体系;针对公路设计因素与交通安全之间关系存在未确知的特点,在未确知测度空间的基础上,构建了一级公路设计安全评价的未确知测度模型。通过单指标未确知测度、多指标综合测度计算以及指标定权等过程,实现对一级公路设计安全效应的综合评价。实例分析表明,运用未确知测度模型进行一级公路设计安全评价问题研究,理论上是可行的,评价结果是可信的,从而为信息不确定条件下的公路设计安全性提供了一种新方法。In order to provide quantity evaluation for the first-class highway,index system of safety assessment for the design of the first-class highway was built.Regarding the characteristics of uncertainty on the relationship between design factors of highways and traffic safety,the unascertained measurement model of safety assessment for the first-class highway design was established.Through unascertained measurement of single indicator,calculation of multiple indicators comprehensive measurement and indicators weight determination process,comprehensive assessment of first-class highway design was realized.Studies indicated that it is theoretically feasible to use unascertained measure model to study safety evaluation problem of first-class highway design and assessment results are credible,thus providing a new approach for safety assessment of highway design under unascertained conditions.
