Research on Shenzhen Metro Traffic Based on Complex Network Theory

Abstract

In order to better understand the advantages and disadvantages of the existing rail transit network in ShenZhen, this paper provides a reference for the planning and improvement of the rail transit network. Based on the complex network theory, this paper first builds the topology model of P-space and C-space, and then calculates the characteristics of the network topology model in different space, including node degree, network average degree, The maximum degree of nodes in the network and node minimum degree, the maximum and minimum distances of the network, the shortest average network path and network aggregation coefficient. The final conclusion is that under the P space: degree of network distribution is mainly around the network average degree, the average shortest path of the network is very small, the clustering coefficient of the network is very large, and the nodes whose clustering coefficient exceeds 0.97 account for 95.24% of the total nodes The distribution obeys the exponential distribution, which verifies that the ShenZhen rail transit network is a smaller world network.
