摘要
依据城市轨道交通网络节点的网络结构特征和进出站客流时间序列特征,提取了节点划分指标,采用主成分分析方法选取了合适的聚类变量,通过层次聚类分析方法将节点进行分类。最后以北京市轨道交通网络为例进行了节点划分的实例计算,将其节点划分为六类,并对聚类分析的结果进行评价,结果表明所提出的方法具有较好的应用价值。
In this paper, in accordance with the structural characteristics of the urban rail transit networks, we extracted the indexes for the node partition of the networks, then used the principal component analysis to choose the suitable cluster parameters and categorized them using the hierarchical clustering process. At the end, in the case of the rail transit network of Beijing, we practically calculated the partition of the nodes of the network into six kinds and assessed the result using the cluster analysis method.
