在对一个实际的城市交通系统进行复杂网络描述的基础上,构造了该城市交通系统的耦合映像格子模型,利用该模型研究了城市交通系统的相继故障问题,应用计算机仿真手段研究了干扰强度和网络相继故障的关系,网络相继故障在攻击条件下对于节点度数的敏感性以及不同攻击策略下网络相继故障的传播问题,对实际城市交通系统的规划、设计、建设和管理具有现实意义.
Based on a complex network description of an actual urban transport system, a coupled map lattice model of the urban transport system is constructed. Using the model, the successive failure problems of the urban transport system are studied. The computer simulation methods are used to study the interference intensity and The relationship between successive failure of network, the sensitivity of successive failures of network to the degree of nodes under attack conditions and the propagation of successive failures of network under different attack strategies have practical significance for the planning, design, construction and management of actual urban traffic system.
