基于集对分析理论的高速公路线形适应性评价

Evaluation of Highway Alignment Adaptability Based on Set Pair Analysis Theory

针对当前高速公路线形适应性评价指标选取不全面以及评价结果可靠性低等问题,文中从车辆运行的角度构建了高速公路线形适应性综合评价体系,将连续性、舒适性、安全性3个方面的评价指标纳入到综合评价体系,并引入集对分析理论,利用联系度函数建立评价指标与各评价等级间的联系,解决相邻评价等级边界模糊问题。同时,将评价模型应用于鹤大高速相关路段,评价结果表明了该方法的有效性与可靠性。

For the problems of alignment adaptability evaluation index selection＇s deficiency and the unreliable evaluation results, in this paper the comprehensive evaluation system of highway alignment adaptability is constructed from the point of vehicle operation and the evaluation indexes about continuity, comfort and safety are put into the unified comprehensive evaluation system. The introduction of set pair analysis theory establishes contact between evaluation index and evaluation degree by contact degree function and solves the problem of fuzzy boundary problem of adjacent evaluation degree. At the same time, the evaluation model is applied to the some sections of Hegang-Dalian Expressway. The results show that the method is effective and reliable.
