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。
In view of the problems of incomplete selection of linear adaptive evaluation indexes and low reliability of evaluation results, this paper constructs a linear adaptive comprehensive evaluation system of expressways from the point of view of vehicle operation. Continuously, comfortably and safely The evaluation index is integrated into the comprehensive evaluation system, and the theory of set pair analysis is introduced. The connection degree between the evaluation index and each evaluation level is established by using the connection degree function to solve the fuzzy boundary problem of the adjacent evaluation level. At the same time, the evaluation model is applied to related sections of Hedong Expressway. The evaluation results show the effectiveness and reliability of the method.
