Abstract

With the consideration of network structure and travelers’ path choice behavior in the congested traffic network, we study the effects of network topologies with degree-degree uncorrelation and correlations (assortative and disassortative correlation) on the performance of traffic network. How the effects of rewiring probability and the degree distribution exponent impact on the traffic congestion and the network efficiency are mainly analyzed. It is found that the correlated network is more vulnerable to traffic congestion compared with uncorrelated ones. Therefore, the uncorrelated network can support much more volume of traffic and have a larger carrying capacity when the traveler’s choice behavior is considered.
