| Abstract: | We analyze the statistical properties of the urban public bus networks of two cities (Beijing and Chengdu) in China. To this
end, we present a comprehensive survey of the degree distribution, average path length, and clustering of both networks. It
is shown that both networks exhibit small world behavior and are hierarchically organized. We also discuss the differences
between the statistical properties displayed by the two networks. In addition, we propose a weight distribution approach to
study the passenger flow through the public bus networks we considered. A hierarchical structure is observed here also. |
