TY - JOUR PY - 2018// TI - A comprehensive risk analysis of transportation networks affected by rainfall-induced multihazards JO - Risk analysis A1 - Liu, Kai A1 - Wang, Ming A1 - Cao, Yinxue A1 - Zhu, Weihua A1 - Wu, Jinshan A1 - Yan, Xiaoyong SP - 1618 EP - 1633 VL - 38 IS - 8 N2 - Climate change and its projected natural hazards have an adverse impact on the functionality and operation of transportation infrastructure systems. This study presents a comprehensive framework to analyze the risk to transportation infrastructure networks that are affected by natural hazards. The proposed risk analysis method considers both the failure probability of infrastructure components and the expected infrastructure network efficiency and capacity loss due to component failure. This comprehensive approach facilitates the identification of high-risk network links in terms of not only their susceptibility to natural hazards but also their overall impact on the network. The Chinese national rail system and its exposure to rainfall-related multihazards are used as a case study. The importance of various links is comprehensively assessed from the perspectives of topological, efficiency, and capacity criticality. Risk maps of the national railway system are generated, which can guide decisive action regarding investments in preventative and adaptive measures to reduce risk.
