Structural Property Analysis of Urban Street Networks Based on Complex Network Theory

Complex network theory provides a new approach for exploring the topological structure and statistical character of urban street networks.In this paper,complex network theory is applied to urban street networks.Firstly,some approaches for analyzing complex networks are described.Some indexes such as characteristic path length,clustering coefficient,degree distributions,assortative or disassortative coefficient,network resilience are choose.Furthermore,the methods of the modeling of urban street network are summarized,and the angle-based dual method is used.Finally,taking Changsha street networks as an example,processing spatial data and statistical index based on ArcGIS and MatLab,some complex network properties of Changsha street networks are analyzed and some conclusions are made.
