基于物元分析的轨道交通线网方案分级测度

Evaluation Model of Urban Rail Transit Network Based on Matter-element Analysis

针对传统轨道交通线网分级测度存在信息屏蔽、主观性强、无定量分析的问题,根据物元分析理论,构建基于物元分析的轨道交通线网分级测度模型,在此基础上建立城市轨道交通线网评价指标体系,通过成都市轨道交通远景线网规划方案进行实例测算。结果表明,3个预选方案的综合关联度值分别为B级-0.232,A级-0.224,B级-0.157,模型测算的最优线网与目前成都主推线网一致。说明构建的物元分析测算模型应用于轨道交通线网方案分级测度是可行的。

Focusing on the classification information shielded and no quantitative analysis of Urban Rail Transit Network,this paper sets up an evaluation model based on the Matter- element analysis and establishes the evaluation index system of for Urban Rail Transit Network. The method was applied to evaluate three rail transit network plans of Chengdu,The results show that the associated value of the three pre- integrated solutions are class B- 0. 232,A grade- 0. 224,Class B- 0. 157,which are similar to the character of Chengdu Urban Rail Transit network. It can be concluded that it is feasible to apply the matter- element analysis to Urban Rail Transit Network evaluation.
