城市公交网络鲁棒性分析模型研究

城市公交网络的鲁棒性是考核城市公交系统性能的重要指标，对其分析将有助于更好地提出评价和优化措施。本文基于二分图模型，构建了城市公交系统的公交原始网络模型、公交站点网络模型和公交线路网络模型，定义了城市公交网络的拓扑结构鲁棒性指标，提出了针对大规模网络的鲁棒性分析的快速算法。最后以北京市公交系统为例，对三种公交网络模型在随机攻击和蓄意攻击下的鲁棒性进行了分析。

Robustness Analysis of Urban Transit Networks

The robustness is an important performance index of urban transit networks. The analysis of this will lead to better evaluation and optimization measures of urban transit systems. In this paper, first, three types of urban transit system models are proposed based on the bipartite graph model, namely the original transit network, the transit stations network and the transit lines network. Then a robustness index for urban transit networks is defined to meet the practical requirement of traffic transit systems. A fast robustness analysis algorithm is designed for the robustness analysis of large-scale networks. Finally, the robustness of Beijing transit system is analyzed under the random attack and intentional attack.
