The improved degree of urban road traffic network: A case study of Xiamen, China

摘要: Abstract The complex network theory is applied to the study of urban road traffic topology, and we constructed a new measure characterize an network. It inspiring quantify interaction more appropriately between nodes in networks, especially field traffic. takes into account properties lanes (e.g. number lanes, width, direction). As much, it comprehensive comparison previous measures. can be used grasp features street clearly. We this Xiamen, China. Based on standard method from statistical physics, examined detail distribution found that (1) due limitation space geographic attributes, traditional research conclusions acquired by using original definition degree primal approach modeled are not very persuasive; (2) both direction connection degree’s odd or even classifications need analyzed specifically; (3) improved presents obvious hierarchy, hierarchical values conform power-law distribution, correlation our shows some significant segmentation
