复杂网络下地铁-公交路网级联失效研究

Study of Subway-Bus Network Cascade Failure under Complex Network

为研究城市公共交通网络的性能,以复杂网络理论为基础,对武汉市公交网络和地铁网络进行系统性分析,利用改进的Space-l方法构建双层复合网络,并进行网络受到自然灾害后的性能影响分析,以网络效率、网络连通率和故障站点比率作为网络性能的度量指标,对负载重分配下节点的非线性容量转移模型中的参数进行分析,并对有无级联失效下蓄意和随意两种攻击方式对复合网络破坏程度及单一网络与复合网络受到攻击后造成的影响的程度进行对比并得出了结论。

In order to study the performance of the urban public transport network,based on the complex network theory,this paper systematically analyzes the bus network and subway network in Wuhan,uses the improved Space-L method to construct a double-layer composite network,and analyzes the performance impact of the network after natural disasters.This paper compares the degree of damage to the composite network and the impact of the single network and the composite network under the risk of cascading failure,deliberate and arbitrary,and draws conclusions.
