在客运专线网络结构下,根据客流节点聚类原理,将客运需求、路网属性、客运能力和社会属性作为聚类分析要素,建立客流节点评价指标体系,运用层次分析法对客流节点进行综合评价。在此基础上应用K—均值聚类方法对客流节点评价得分进行聚类研究,通过实例分析得到我国铁路客运专线客流节点的4种类型,并对这4类客流节点的差异性进行分析论述。
Under the structure of passenger dedicated network, according to the clustering principle of passenger flow node, taking the passenger demand, road network property, passenger capacity and social attribute as the cluster analysis elements, the paper establishes the evaluation index system of passenger flow node, and uses AHP to evaluate the passenger flow node comprehensively . On this basis, K-means clustering method is applied to cluster the evaluation points of passenger nodes, and the four types of passenger nodes of China’s passenger dedicated railway lines are obtained through case studies. The differences between these four types of passenger nodes are analyzed and discussed.
