Weighted Complex Network Analysis of the Difference Between Nodal Centralities of the Beijing Subway System

The centrality of stations is one the most important issues in urban transit systems. central such networks have often been identified using network to-pological measures. In real networks, passenger flows arise from an interplay between dynamics individual person movements and underlying physical structure. this paper, we apply a two-layered model to identify Beijing Subway System, which lower layer infrastruc-ture upper represents flows. We compare various indicators as degree, strength betweenness for model. To represent influence exogenous factors on subway system, reference al-pha centrality. results show that geographic system terms are not consistent with alpha clarify difference by comparing two measures load, indicating approx-imates load better than betweenness, it can capture direction volume along links into out empirical findings give us some useful insights node cen-trality
