贵阳公交复杂网络抗毁性分析

Research on Invulnerability of Public Traffic Complex Network in Guiyang

城市公共交通系统可以抽象为由公交线路和停靠站点构成的网络,公交网络构成了一个典型的复杂网络。复杂网络的研究在过去几年得到了迅速发展,其中复杂网络的抗毁性是研究焦点之一。在本文中,以贵阳市的公共汽车交通系统中的停靠站点网络为研究对象,测试了网络在随机攻击和选择性攻击情况下的抗毁性。结果表明,该网络对节点的随机攻击具有较强的抗击能力,而对选择性攻击的抗击能力较弱。

Urban public transportation system can be abstracted as a complex network composed of stops and public transportation lines,and urban public traffic network is a typical complex networks.In the past few years,as a focus,the study on invulnerability of complex networks has made quick progress along with the development of complex network theory.In this paper,the invulnerability of Guiyang bus stop network on error and attack is studied.The result indicates that the network displays a relatively high degree of robustness against error,but display a relatively low degree of robustness against attack.
