高速公路交通事故威胁程度预警评价模型

Evaluation and early-warning Model of Accident Threat Level on Expressway

为了评价高速公路交通事故对交通运行安全的影响程度,基于二级模糊综合评判法,构建了高速公路交通事故威胁程度预警指标体系模型。其中包含评价指标及预警等级。将这一模型运用到一起交通事故实例的研究中,分析各指标对交通运行的威胁程度,根据模型的计算方法和最大隶属原则,确定了事故威胁程度的预警等级。

The occurrence of accident in expressway could threaten traffic operation safety.In order to evaluate the threat level of accident in expressway,secondary fuzzy comprehensive evaluation method was applied to build expressway accident early-warning index system model.Evaluation index and early-warning class were included in the model.It was used in an accident study,and accident index threat level to traffic operation was analyzed.According to calculation and maximum membership principle,the early-warning class of accident threaten was determined.
