Adaptive transition of critical transport infrastructures

Environmental and resource constraints are crucial for adapting Critical Transport Infrastructures (CTIs) to the ever-changing environment. Inadequate resources coupled with the implementation of non-resilient and unsustainable mitigation measures pose a considerable risk, potentially steering CTIs towards maladaptation. This paper investigates the interplay of CTIs’ resilience and adaptive capacity under multiple hazards. In line with this, the resilience level of a bridge case study is estimated with the use of resilience indices. Beyond resilience assessment, the research scrutinizes the efficacy of potential mitigation measures designed to facilitate the adaptive transition of these critical assets. In a proactive approach to mitigate maladaptation risks, the chosen measures undergo a thorough evaluation using sustainability indices. This evaluation considers a comprehensive spectrum of criteria, encompassing societal, environmental, and economic factors. By blending resilience and adaptive capacity analyses with sustainability assessments, this paper aims to provide a holistic framework for fortifying CTIs against the uncertainties of a dynamic environment. Through a careful examination of both the challenges and opportunities, it strives to guide the implementation of resilient and sustainable strategies, ensuring the continuity and efficiency of critical transport infrastructures in the changing world.
