Resilience-based decision making for transportation infrastructure

Transportation infrastructure is jeopardized by threats coming from natural hazards, which are likely to be more severe and frequent due to climate change. These threats need to be coped with the adequate measures, which are increasingly determined using a resilience-based approach. The resilience-based approach is similar to traditional risk-based approaches in asset management, which is broadened to consider a recovery phase after failure(s) in more detail. The topic has been treated both in research and practice, but so far the measure of resilience is not used as a core component in decision making. The paper deals with quantification of resilience and the potential for its application in practice of asset management. The main challenges are setting a value system and a system boundary in measuring benefit that comes from infrastructure. An example of resilience evaluation is given to present importance of development of decision support tools .
