以洛(阳)-卢(氏)高速公路长陡下坡路段为背景,介绍了长陡下坡路段安全隐患分析方法,该方法是采用层次分析法与模糊函数相结合得出综合模糊评价模型,经该模型计算得到路段的综合隶属度值,根据综合隶属度值的范围来判断存在安全隐患的位置,并提出了针对性的改善措施方案。 Based on the long and steep downhill section of Luoyang expressway, this paper introduces the analysis method of potential safety hazard on the long and steep downhill section. The method combines the analytic hierarchy process with the fuzzy function to get the comprehensive fuzzy evaluation model. The model calculates the comprehensive membership value of the road section, determines the location of the potential safety hazard according to the range of the integrated membership value, and proposes the solutions for the improvement measures.
