理想解法动态评价模型在城市现代有轨电车适用性评价中的应用

Application of TOPSIS Dynamic Evaluation Model in the Evaluation of the Applicability of Urban Modern Tram

在评价对象、评价指标等二维数据基础上,引入城市轨道交通建设初期、近期和远期等时间序列,将二维数据扩展为三维数据。文章以南京市麒麟地区现代有轨电车规划建设为例,采用理想解法动态评价模型,对现代有轨电车、BRT、APM和中低速磁悬浮等系统的适用性开展动态评价研究。文章通过分阶段和总体评价,得出在南京市麒麟地区,现代有轨电车比BRT、APM和中低速磁悬浮有着更好的适用性的结论。

On the basis of two-dimensional data such as evaluation object and evaluation index,this paper introduces time nodes such as the preliminary stage,the short-term stage and the long-term stage,and extends the two-dimensional data with time series data to threedimensional data.Taking the planning and construction of modern tram in Qilin district of Nanjing as an example,dynamic evaluation of the applicability of modern tram,BRT,APM and medium-low speed maglev systems is studied by using the TOPSIS dynamic evaluation model.Through phased and overall evaluation,it is concluded that modern tram has better applicability than BRT,APM and medium-low speed maglev in Qilin area of Nanjing.
