基于SE-DEA的城市轨道交通线网规划方案优选

城市轨道交通线网规划初始方案的选择是城市规划者与建设者应予以重视的关键问题。针对已有研究方法中所存在的不足,提出一种基于超效率数据包络分析(SE-DEA)的轨道交通线网方案比选方法,构建城市轨道交通线网方案的综合评价指标体系并有效筛选出决策单元的输入输出指标。结合某市轨道交通线网规划方案进行实证研究,模型所测结果与该市主推线网方案一致,验证方法的可行性与有效性。所提出的方法依据方案间的相对效率,对预选方案进行优劣性排序,可为城市管理者提供决策依据。

Selection of Urban Rail Transit Network Planning Scheme Based on SE-DEA Method

The selection of initial urban rail transit network planning scheme is a key issue attracting urban planners and urban builders. According to the insufficiencies of current researches,the paper presents a method based on super efficiency data envelopment analysis( SE-DEA) to solve the problem of scheme selection. The input and output index of each decision making unit is worked out based on the comprehensive evaluation index system. In the light of rectification study of the scheme of urban rail transit network planning designed by a city,the results measured by the model are consistent with the scheme recommended by the city. The method can be used to sort the initial urban transit network planning schemes based on the order of efficiency and help urban managers make decisions.
