【摘要】 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.更多还原

【Abstract】 This paper presents an urban traffic system CML(Coupled Map Lattice) model on the base of describing the complex networks features of an actual urban traffic system.We study cascading failures using this model,investigate the relationship between disturb intensity and networks failures using simulation methods.Furthermore,we research the sensitivity of networks fault undergoing attack and the contagion on different attack tactics.These results should be significant for actual urban traffic systems planning,designing,building and management.更多还原
