Research on Topology Structure of Urban Mass Transit Network
摘要
Abstract
This paper firstly analyzes the network transfer mechanism between lines in the whole Shanghai mass transit network at macroscopic level. Then it discusses the topology structure for the whole mass transit network. It finds out that the network has different natures from the perspectives of Space L and Space P. In Space L, the values of net work degree are relatively smaller and the degree values of more than 80% nodes are less than 2 with concentrated distribution of degree values; the average shortest path of the entire network is the average value of actual station numbers in the path from any station to any station with relatively larger length of shortest path and small network clustering coefficient close to 0. In space P, the values of network degree are relatively larger with wide distribution of degree values; the length of the average network shortest path is relatively small-er, which indicates the average transfer times from a station to any station; the network clustering coefficient is very large, which is more than 0.9, and more than 85% nodes’ network clustering coefficients in Shanghai mass transit network are 1.关键词
