基于多属性决策分析理论的地铁选线方法研究

Research on metro route selection method based on multi attribute decision analysis theory

地铁选线设计是一项需多专业协同、规划性和综合性较强的工作,传统选线方法过于依赖工程师主观判断,缺乏定量分析,无法满足精细化设计需求。文章针对传统选线方法的不足,提出一种基于多属性决策分析理论的地铁选线方法,并以佛山地铁4号线方案研究为例进行分析。该方法从线路条件、车站服务功能、拆迁难度和代价、穿越铁路协调难度4个维度对线路方案进行量化分析评价以及优劣排序,从而建立更加全面、精准、有针对性的地铁选线方法。

Metro route selection design is a work that needs multi-technical fields cooperation,planning and comprehensiveness.The traditional route selection methods rely too much on the subjective judgment by engineers,lack of quantitative analysis,and cannot meet the needs of fine design.In view of the shortcomings of traditional route selection methods,this paper proposes a metro route selection method based on multi-attribute decision analysis theory,and takes Foshan metro line 4 as an example.In order to establish a more comprehensive,accurate and targeted metro route selection method,this paper explicates a method of quantitative analysis and evaluation of the route schemes from four dimensions:line conditions,station service functions,demolition difficulty and cost,and coordination difficulty.
