基于灰色关联的城市地铁网评价模型——以杭州市地铁网为例

Evaluation model of urban subway network based on grey correlation--A case study of Hangzhou subway network

为促进城市地铁的科学发展,对地铁网系统进行了评价。通过综合考察影响城市地铁网系统评价的运营效益、环境效益、社会效益、服务效益、交通效益五个因素,建立城市地铁网系统的综合评价体系及模型。在定义城市地铁网系统评价区间标准的基础上,运用灰色关联分析法对地铁网系统的评价进行了具体分析和计算;进而用该模型对杭州市现有地铁网进行了综合评价。结果表明,杭州市地铁网的评价等级为三级的占20.9%,评价结果为一般。这表明杭州地铁网系统比较合理,还应重点加强、完善该市的地铁线路网络系统,促进整个城市交通的协调发展。

The subway network system is evaluated for the sake of boosting the scientific development of urban subway.The comprehensive evaluation system and model of urban subway network system are established by comprehensively investigating five factors that affect the evaluation of urban subway network system,including operation benefit,environmental benefit,social benefit,service benefit and traffic benefit.On the basis of defining the evaluation interval standard of urban subway network system,this paper analyzed and calculated the evaluation problem of subway network system with grey correlation analysis method.Then the model was used to comprehensively evaluate the existing subway network in Hangzhou.The result shows that 20.9%of the subway network in Hangzhou has the third grade,and the evaluation result is in the general level.This shows that Hangzhou subway network system is fairly reasonable,and needs to be strengthened and improved to promote the coordinated development of the whole city s traffic.
