基于改进灰色定权聚类的城市轨道交通网络规划方案优选研究

综合考虑路网结构合理性、建设实施性、运营效果、社会经济效益以及城市发展的协调性等五方面的影响因素,建立了城市轨道交通网络规划方案综合评价指标体系。引入高斯白化函数、等面积法则确定参数和基于信息熵的聚类权的标定法,提出了改进灰色定权聚类优选模型,并将其应用于某市轨道交通规划方案优选,评价结果与实际专家评审结果一致,验证了该模型的有效性和实用性。

Planning Optimization of the Urban Rail Transit Network Based on Improved Grey Fixed Weight Clustering

Firstly,in order to optimize the urban rail transit network program planning,this paper establishes an urban rail transit network planning comprehensive evaluation index system.It considers the rationality of the road network's structure,implementation of the construction,operating results,social and economic benefits,and the coordination of urban development.Secondly,it proposes an improved grey fixed weight clustering optimization model according to the five influencing factors.The model selects the Gauss...
