Abstract:: Based on graph theory and complex network theory, ten typical cities urban rail transit network in China were selected, and their topology characteristics were analyzed. And in which the complexity, connectivity, and extensibility of rail transit network were used to characterize the macroscopic traits, network degree, distribution of network degree, length of the shortest path and its distribution, and clustering coefficient were considered as the microscopic trait variables, and network efficiency and the maximum connection subgraph were chosen as the stability index. The results show that the rail transit network in most cities of China were in the primary stage of development, and the “triangle” structure and large transfer station contributed significantly to the efficiency of the whole network. In view of the macroscopic characteristics, the structure of the transit network studied had scalefree and smallworld network features, and the large transfer stations were the key factor that affected the development pattern of the network. While analyzing the network stability, it can found that rail transit network stable while dealing with random attacks, but becomes weak in deliberate attacks, so it is nearly impossible to improve the network stability by increasing its size. The large transfer station can also help improve the stability of the entire rail transit network. 6 tabs, 12 figs, 27 refs.
