Analysis of Urban Road Traffic Network Based on Complex Network

Urban road traffic is a typical network. The analysis and study of the topology structure is the basis of the traffic state evaluation and the traffic organization optimization. This paper redefines the urban road traffic weighted network model with considering the functional properties of urban road network and presents the traffic efficiency concept of the road section in the urban road traffic network. According to the different edge weights which are determined by the different attribute of the edges, we analyses the statistical characteristic of the urban road traffic network based on the three different network models which include the length weighted network model, the traffic capacity weighted network model and the traffic efficiency weighted network model. We take Beijing road traffic network as an example to illustrate the effectiveness of the analysis methods for the structural characteristics. (C) 2016 Published by Elsevier Ltd.
