Urban Design and Spatial Analysis

With the rapid development of urban rail transit, it is more and more necessary to study its complex network structure. Taking Chengdu which is an important city in the west as an example, calculating its static statistic index under the complex network. The network structure has 136 nodes, 146 lines under the space L model, and the average degree is 2.147, the average path length is 13.1465, network number is 0.091, network connectivity is 0.0159, network efficiency is 0.1237. The overall network is a tree-like structure with small-world characteristics. The index of network number, efficiency and connectivity is not very important, which shows that the utilization ratio is not enough, the connection between the nodes is not open, and there is a certain waste on the topology structure, which provides the development and progress space for the planning of the future lines.
