道路交通安全事故的发生与交通环境有密不可分的关系。引入未确知测度数学理论模型,将道路安全分为4个等级,建立天气状况、路面状况、地形状况等交通环境因素的评价指标体系,分析给定了分级标准,构建了道路安全状况评价指标的未确知测度函数,用信息熵法求取指标权重,依据置信度识别准则对道路安全状况进行识别,得到了一定交通环境下的道路交通安全等级,并结合实例进行了分析。研究结果表明,该方法能有效解决道路安全等级评价中诸多不确定性问题,操作性强,结果可靠。
道路交通安全事故的髮生與交通環境有密不可分的關繫。引入未確知測度數學理論模型,將道路安全分為4箇等級,建立天氣狀況、路麵狀況、地形狀況等交通環境因素的評價指標體繫,分析給定瞭分級標準,構建瞭道路安全狀況評價指標的未確知測度函數,用信息熵法求取指標權重,依據置信度識彆準則對道路安全狀況進行識彆,得到瞭一定交通環境下的道路交通安全等級,併結閤實例進行瞭分析。研究結果錶明,該方法能有效解決道路安全等級評價中諸多不確定性問題,操作性彊,結果可靠。

Road traffic safety accidents are closely linked with traffic environment.Based on uncer-tainty measure theory,the road safety condition was divided into four grades,and the evaluation index sys-tem was established,which includes climate condition,pavement condition and landform condition;mean-while,the grading standards were given.Uncertainty measure functions of evaluation index are obtained u-sing the uncertainty measure theory,information entropy method is used to calculate weights of the evalua-tion indices.Credible degree recognition criteria are used to evaluate road safety level.Finally,the analy-sis is made with example.The results show that this evaluation method has solved the uncertainty factor problems of road safety grade evaluation;the analysis result proves the method operable and its result credible.
