Dynamical hysteresis phenomena in complex network traffic.
In this Brief Report, the dynamical hysteresis is investigated in constant-density traffic system of scale-free, small-world, and lattice networks. With the local-searching strategy, hysteresis persists for scale-free networks, while it disappears for small-world networks and lattice grids when the handling ability of nodes is higher than a certain threshold. With the shortest-path-routing strategy, hysteresis persists for all three networks investigated. When using shortest-path strategy, the system is easy to congest and difficult to recover to free-flow state.
