Abstract:

Metro network is a complex network including stations and lines. We investigate the characteristics of metro network and its evolution with complex network theory. We analyze evolution characteristics of Beijing, Shanghai and Guangzhou metro network by introducing six network characteristic parameters and taking the metro network of the three cities as subjects. We also analyze the congestion phenomenon from the topology perspective based on the statistical results. Our research conclusion will provide a theoretical basis for the future development of urban rail transit.

Key words: metro, complex network, network evolution
