城市地铁线路方案比选问题的研究

Study on the Problem of Subway Line Scheme Selection

当前,城市地铁规划建设已成为大城市交通发展的一项重要内容,地铁线路方案比选问题也就尤为突出,急需建立一个综合比选方法,来解决复杂的方案选择问题以避免因主观因素而造成的选择偏差。为此,该文建立了方案比选模型,采取将delphi法、层次分析法和灰色关联分析法相结合的形式,对地铁线路方案进行比选,并通过实例证明该方法的可行性以及评价问题的全面性和公正性。

Currently subway planning and construction has become an important part of the development of metropolitan transportation, and the problem of subway line scheme selection is becoming more acute. It is urgent to establish a comprehensive comparison and selection mode to address the complex program selection problems and avoid selection bias caused by subjective factors. In this paper, a planning model was set up combined with delphi method, AHP and Grey relation analysis, to compare and select subway line schemes. And an example was given to prove the feasibility of this model and the comprehensiveness and impartiality of its evaluation.
