为了保证地铁交通网络安全、高效地运行,提高地铁网络的抗攻击能力,根据复杂网络基本理论,从乘客出行延误时间、需求未满足乘客数量2个方面研究连边和站点的重要性,进而构建网络服务效率评价指标体系,以评价整个地铁网络的脆弱性。以上海地铁网为例,借助Matlab模拟不同攻击方式下的网络服务效率。结果表明,站点和连边的重要性随着网络中其他连边或站点的失效而发生变化;站点的脆弱性受其地理位置、运送旅客数量及可换乘性的综合影响;上海地铁网对连续重要性攻击表现出最大的脆弱性。
In order to ensure the safe and efficient operation of the subway traffic network and improve the anti-attack capability of the subway network, the importance of the connected side and the site is studied based on the basic theory of complex networks from two aspects of passenger travel delay time and the unmet demand. Network service efficiency evaluation index system to evaluate the vulnerability of the entire subway network. Take Shanghai Metro Network as an example, simulate the efficiency of network service under different attack modes with Matlab. The results show that the importance of sites and connected edges changes with the failure of other links or sites in the network. The vulnerability of sites is affected by the geographical location, the number of passengers transported and the interchangeability. Shanghai Metro Network Continuous importance attacks show the greatest vulnerability.
