Abstract

With the rapid pace of urbanization and the rising car ownership, traffic congestion events (TCEs) are becoming more prevalent, which have significantly affected the safety and reliability of urban public transport systems. Proper assessment of the resilience of integrated bus-rail networks to such disruptions is therefore of practical significance. However, the existing studies mainly focus on single transportation mode with limited attention to integrated bus-rail networks under TCEs. Moreover, the influence of the dynamic congestion propagation process on the network resilience is often ignored. To address these gaps, this study proposes a model to assess the resilience of an integrated bus-rail network under TCEs by considering the impact of the dynamic congestion propagation process. Experimental results imply that an integrated bus-rail two-layer network is more resilient to TCEs than the single layered bus network in Chengdu, and the influence of the dynamic congestion propagation process is critical in the resilience assessment.

交通拥堵事件下考虑动态拥塞传播过程的公交轨道网络弹性评估

随着城市化进程的加快和汽车保有量的增加，交通拥堵事件日益普遍，严重影响了城市公共交通系统的安全性和可靠性。因此，正确评估公共汽车-铁路综合网络对这种中断的恢复能力具有实际意义。然而，现有的研究主要集中在单一的交通方式上，对交通枢纽下的公交轨道综合网络研究较少。此外，动态拥塞传播过程对网络弹性的影响往往被忽略。为了解决这些差距，本研究提出了一个模型，通过考虑动态拥塞传播过程的影响来评估TCEs下综合公交轨道网络的弹性。实验结果表明，成都市公交轨道两层网对交通拥堵的弹性优于单层网，且动态拥堵传播过程的影响在弹性评估中至关重要。

期刊介绍： Elsevier publishes Reliability Engineering & System Safety in association with the European Safety and Reliability Association and the Safety Engineering and Risk Analysis Division. The international journal is devoted to developing and applying methods to enhance the safety and reliability of complex technological systems, like nuclear power plants, chemical plants, hazardous waste facilities, space systems, offshore and maritime systems, transportation systems, constructed infrastructure, and manufacturing plants. The journal normally publishes only articles that involve the analysis of substantive problems related to the reliability of complex systems or present techniques and/or theoretical results that have a discernable relationship to the solution of such problems. An important aim is to balance academic material and practical applications.
