为了保证城市公交网络的安全运营、提高整个交通网络运行效率，以成都市公交网络为例，分析了该网络的拓扑结构特性，研究了该网络在随机攻击和蓄意攻击下的抗毁性。仿真结果表明，网络在随机攻击和基于节点度的攻击下连续移除节点的数目几乎不对网络的抗毁性产生影响，而在基于节点介数和效率的攻击下连续移除的节点个数越少，网络的抗毁性越差；基于节点介数的攻击对网络抗毁性产生的影响要比随机、基于节点度和效率更为显著。

To ensure the safety of the urban transit network so as to improve the operation efficiency of the entire traffic net-work,this paper took the transit network of Chengdu city for instance,it analyzed the invulnerability under random and delib-erate attacks based on revealing the network topology.The simulation results show that the node number removed from the net-work affects the invulnerability little in both random attacks and deliberate attacks on the basis of node degree.At the same time,it finds that the less node number removed from the network,the worse invulnerability the network shows in deliberate attacks based on not only node betweeness but node efficiency.Furthermore,the impacts of deliberate attacks based on node betweeness on the network invulnerability are more remarkable than those based on node degree and efficiency.
