Research On The Complexity Of Xining's Public Transportation Network Based On GIS

This paper adopts the basic theory of complex network and uses empirical research as a guide.Starting from the network topology of Xining public transportation system,the public transportation routes and stations in Xining are vectorized by GIS,and the public of Xining City is constructed according to Space-L method.Traffic site network and Xining public transportation route network.By analyzing the three topological parameters,degree distribution,shortest path distance and aggregation coefficient in the Xining site network and the Xining line network,the statistics and related analysis of these parameters are carried out to obtain the public transportation network and site network of Xining.The various topological parameter values under the network model are analyzed,and the topological parameter values are analyzed.It is concluded that the public transportation network of Xining meets the scale-free characteristics and the small world characteristics,and belongs to the complex network.However,the number of stations and sides in the public transportation network in Xining is small,and the overall scale of the public transportation network in Xining is small.Two kinds of attacks in Xining City's public transportation network have been deliberately and stochastically studied.It proves that the public transportation network in Xining shows strong robustness under random attacks and strong vulnerability under deliberate attacks..Finally,based on the analysis of the data results,the corresponding suggestions and countermeasures for the problems in the public transportation network of Xining City are put forward.
