We propose a simple cellular automaton model to study the traffic dynamics in a roundabout. Both numerical and analytical results are presented. We are able to obtain exact solutions in the full parameter space. Exact phase diagrams are derived. When the traffic from two directions mixed, there...

By incorporating local traffic information into the basic shortest path routing policy, we propose a congestion …-free networks with different clustering coefficients and in different congestion phases. We find that there exists an optimal value … for the tunable parameter in the congestion awareness strategy. Though the optimal value increases slowly as the traffic …

In this work, we propose and study a model for the diffusion of congestion in complex networks. According to the … proposed model, the level of congestion on each node will be self-organized into the same value. The diffusion of congestion … effective strategies for diffusing the local and the global congestion in complex networks, respectively. …

Random networks were generated with the random configuration model with prescribed truncated power-law degree distributions, parameterized by an exponent, an offset, and an exponential rolloff. As a model of an attack, each network had exactly one of its highest degree nodes removed, with the...
