为了对山区高速公路曲线路段危险性进行识别,提高道路安全管理水平和资金利用率,提出了一种道路危险路段识别的方法,重点考虑了导致事故发生的环境因素和道路设计因素,应用模糊推理的方法,对西部某山区高速公路危险路段进行了识别,并取得了良好的效果。方法应用结果表明:道路几何因素和环境因素对山区高速公路的危险性具有较大影响;运用基于T-S模糊推理方法得到的结果与实际事故资料相符。
In order to identify the dangerous sections of the mountainous expressways and improve the level of road safety management and capital utilization, a method of road section identification is put forward. The environmental factors and road design factors which lead to the accident are considered, and fuzzy reasoning Approach to identify the dangerous sections of a highway in western mountainous areas and achieved good results. The application results show that: the road geometry and environmental factors have a great impact on the risk of highway in mountainous area; the results obtained by using T-S fuzzy inference method are consistent with the actual accident data.
