Economic-Driven Weighted Complex Networks Evolution and Simulation of Expressway
The topology,evolution and characteristics of the motorway network problem under economic driving factors are discussed in the paper.On the basis of the BBV model,a complexity metric weighted network evolution model with the standard of node strength and economical flow is proposed,and numerical simulation and analysis using MATLAB software are discussed about the influences of economic flows incremental network topology and the reality of urban economic network attributes on the expressway network evolution.The results of the simulation show that the expressway network is a typical complex weighted network,whose points right distribution follows a power law distribution with a heavy tail characteristic;economic flow increment becomes the driving factor of the evolution of network topology,and urban economic development of the properties of real networks plays a decisive role.The results of this study would provide a theoretical basis and reference for the construction and optimization of the expressway and for the construction of regional economic integration.
