Abstract: As extreme weather events enhanced by climate change pose challenges to the resilience of critical infrastructure, the ability to handle disruptions, avoid tipping points, adapt and transform in crises becomes essential. Despite advances in resilience research, there is a need to improve empirical evidence and mathematical models to quantify the systems’ adaptive capabilities to extreme climate-related phenomena, such as floods. This research fills this gap by integrating an agent-based multimodal traffic functional model with a compound failure model to provide valuable insights into adaptation patterns (that is, mode shift and route switching) and risk mitigation in response to flood-related disruptions. The proposed modelling approach not only quantifies the recovery and adaptive capacity against failures, going beyond traditional resilience analyses, but also unveils the key factors that drive adaptation of transportation to flood-induced disasters. These factors include variations in trip demand and network density, which together reveal a universal law of mode shift. The study provides valuable insights into the design of resilient and sustainable critical infrastructure systems, such as transportation, energy and communication systems capable of withstanding severe flood events while maintaining their functionality.
摘要:由于气候变化增强的极端天气事件对关键基础设施的韧性提出了挑战,因此处理干扰、避免临界点、在危机中适应和转换的能力变得至关重要。尽管恢复力研究取得了进展,但仍需要改进经验证据和数学模型,以量化系统对极端气候相关现象(如洪水)的适应能力。本研究通过将基于Agent的多模式交通功能模型与复合失效模型相结合,填补了这一空白,为应对洪水相关中断的适应模式(即模式切换和路由切换)和风险缓解提供了有价值的见解。所提出的建模方法不仅量化了对故障的恢复能力和适应能力,超越了传统的恢复力分析,而且揭示了驱动运输适应洪水灾害的关键因素。这些因素包括出行需求和网络密度的变化,共同揭示了模式转变的普遍规律。该研究为弹性和可持续的关键基础设施系统的设计提供了有价值的见解,例如交通、能源和通信系统,能够抵御严重的洪水事件,同时保持其功能。
