Analysis of Topologic Properties and Road Structure of Tangshan Bus Traffic Network

Tangshan is a city rebuilt after the earthquake. The urban construction was replanned, which directly designed the road structure. Therefore, this paper analyzes Tangshan bus network from two aspects of topologic properties and road structure. After analyzing the data of Tangshan bus network, this paper proposes an analysis method based on complex network theory for Tangshan bus network. This paper first established Tangshan bus line Space-L network model, and obtained node degree, node strength, bearing pressure, and clustering coefficient in the model. And then established transfer Space-P network model, with topologic properties, such as node degree, average distance, closeness centrality and betweenness centrality obtained. In order to distinguish different districts precisely, the bus stops in different districts are marked with different colors in Tangshan bus model figure. Finally, spatial bus road structure is studied for Tangshan including Fengnan district. And according to the analysis results, some feasible suggestions are given. The results of this study may provide reference and guidance for researchers on Tangshan bus route planning and design
