城市轨道交通换乘站布局综合评价方法研究

对城市轨道交通线网交会点是否需要设置为换乘站、换乘站设置对整体线网的优化有何影响、用什么标准衡量和评价换乘站的布局进行深入的研究。根据充分发挥线网整体效率、均衡客流强度、减少乘客无效乘距的指导思想,提出从网络发展水平、居民出行条件改善、运营效果三方面9项指标组成的轨道交通换乘站布局方案综合评价体系,研究指标量化的方法,对城市轨道交通换乘站布局进行多目标模糊综合分析评价。以某市轨道交通线网规划为例,应用评价体系推荐出最优布局方案。

A Fuzzy Synthetic Evaluation Method for Layout of Urban Rail Transit Interchange Stations

This paper expounds whether each interchange point of urban rail transit network needs to be an interchange station, and how the interchange station layout influences the network optimization. To maximize the efficiency of the whole network, balance passenger flow and minimize the invalid riding distance by the passenger, a synthetic evaluation system, which consists of 9 indicators on the part of network development, improvement of passenger trip conditions and operation results, is proposed in this paper. A method for quantifying the indicators is put forward for multiobjective fuzzy synthetic evaluation of the interchange station layout. This evaluation method is employed to identify the best possible design for an urban rail transit line in a city cited as an example.
