Analysis of the topological structure of Shanghai metro network

ZHENG Sujiang;School of Management,Shanghai University of Engineering Science;  
Based on the complex network theory,this paper establishes the model of 16 metro lines in Shanghai under the Space-L method,draws the preliminary topological structure diagram of the metro network through Ucinet,and calculates by using Matlab according to the adjacency matrix of stations: the degree distribution of most stations is 2,the degree distribution of stations is basically similar to that of Poisson distribution; the clustering coefficients of more than 97% stations are 0,and the result shows that the degree distribution of most stations is similar to that of Poisson distribution. The average clustering coefficient of stations is very small,and the average path length is 15.12,which does not have the characteristics of small world network. The cumulative degree distribution of stations in double logarithmic coordinates basically conforms to the power distribution and has the characteristics of scale-free network.
