洪水会对交通基础设施资产造成严重的直接破坏，并对依赖交通网络的社区造成重大的间接损失。因此，了解洪水造成的网络功能和运行恶化，以帮助运输机构减轻或计划失败的后果，就变得至关重要。为了实现这一目标，本研究以交通运输网的实际路段为测试平台，开发了一个网络级多步骤评估框架，以评估洪水相关风险，并对测试平台实施具体的防洪措施。多步骤框架首先完成了洪水前缓解策略投资、洪水后资产回收成本、洪水后网络的间接交通延迟和机会损失的评估。然后，应用生命周期效益成本分析来评估各种防洪策略的性能。这一系统的努力有望提供对网络洪水风险的全面概述，并为优化和优先考虑减灾投资提供以保护为导向的手段，同时确保系统在吸收洪水危害和适应洪水期间部分功能失调的网络操作方面的能力得到充分提高。
Floods can lead to substantial direct damages to transportation infrastructure assets and cause significant indirect losses to communities that rely on the transportation network. This makes it crucial to understand the network's functional and operational deterioration caused by floods to help transportation agencies to either mitigate or plan for consequences of failures. To achieve this goal, this study uses an actual segment of a transportation network as a testbed to develop a network-level multi-step assessment framework to evaluate the flood-related risks and implement specific flood mitigation measures to the testbed. The multi-step framework first accomplishes assessments of the investment of pre-flood mitigation strategies, post-flood asset recovery cost, and indirect post-flood traffic delay and opportunity losses of the network. Then, a life-cycle benefit to cost analysis is applied to estimate the performance of the various flood mitigation strategies. This systematic effort is expected to provide a holistic overview of the flood risk to the network and a conservation-oriented means for optimizing and prioritizing mitigation investments while ensuring that the system resilience is sufficiently improved with respect to capability for absorbing flood hazards and adapting to partially-dysfunctional network operations during floods.
