基于模糊综合评价方法的高速公路防眩设施优化选择

PTIMAL SELECTION OF EXPRESSWAY ANTI-GLARE FACILITIES BASED ON FUZZY COMPREHENSIVE EVALUATION METHOD

防眩设施合理选择直接影响到高速公路的夜间行车安全和工程经济性,为避免防眩设施选择的主观性与片面性问题,文中基于模糊综合评价方法,根据常用的高速公路防眩设施特点,确定了影响防眩设施选择的评价指标体系,计算得出了个评价指标的权重,对防眩板、防眩网和植物防眩三种方式进行模糊综合评价,得出了最优的高速公路防眩设施选定结果。有利于提高高速公路防眩设施选择的客观性与合理性,达到防眩安全与工程经济的综合最佳。

The rational selection of anti-glare facilities directly affects the night traffic safety and engineering economy of expressway. In order to avoid the subjectivity and one-sided problem in the selection of anti-glare facilities, This paper is based on the fuzzy comprehensive evaluation method and based on the characteristics of commonly used highway anti-glare facilities.The evaluation index system that affects the selection of anti-glare facilities was calculated. Besides the weight of evaluation indexes was calculated.And finally the optimization selection result of highway anti-glare facilities was obtained by the comprehensive evaluation of anti-glare board,anti-glare nets and plant anti-glare. These achievements are helpful to improve the objectivity and rationality of the selection of expressway anti-glare facilities and contribute to achieve the best traffic safety and engineering economy.
