Having a vulnerability assessment of a large-scale bus transit network (LBTN), an essential part of urban vulnerability assessment, is indispensable for developing urban transportation sustainability. The complex network approach is usually used to realize this goal because it focuses on a mesoscopic perspective and has a unique advantage of calculation efficiency in large-scale networks. However, the vulnerability assessment of LBTNs is usually tested based on node attacks or edge attacks rather than route attacks because of the widely existing “route collinear problem”, which makes the infrastructure disruption and the route service disruption indistinguishable. This paper establishes a novel vulnerability assessment and visualization framework under the perspective of route service disruption. This framework provides a novel perspective for understanding complex systems, lays the foundation for LBTN risk identification, and significantly lowers the availability barrier of the required data, thereby extending the vulnerability study framework based on a complex network approach, from statistical physics to engineering.

大规模公交运输网络（LBTN）的脆弱性评估是城市脆弱性评估的重要组成部分，对于发展城市交通的可持续性必不可少。复杂网络方法通常用于实现此目标，因为它着眼于介观视角，并且在大规模网络中具有独特的计算效率优势。但是，由于广泛存在的“路由共线问题”，通常基于节点攻击或边缘攻击而不是路由攻击来测试LBTN的漏洞评估，这使得基础架构破坏和路由服务破坏难以区分。本文从路由服务中断的角度建立了一种新颖的脆弱性评估和可视化框架。
