Evolving Model for Scale-Free Network Based on Travel Choice

  • In order to further investigate the mechanism of scale-free networks,an evolving model for scale-free networks based on travel choice was established through analyzing the characteristics of urban resident trip networks,and the three special cases of this model were pointed out.The evolution process of urban resident trip networks was simulated numerically,and the expression of degree distribution exponent was obtained by using the mean-filed theory to show the same result as the simulation result.The research results indicate that urban resident trip networks have scale-free properties and are typical scale-free networks.
