2.5 Resilience

In recent years, many highway agencies have begun to focus on methods to address adverse events that cannot be tackled within the traditional risk-based approach. The focus of asset management activities is to begin from prevention against threats or events that may occur and that may degrade the performance of the asset itself to move towards a new comprehensive “Resilience-based” approach to be able to speed up recovery and restore asset functionality, once disruptive events have occurred. In the following sections, a brief definition of Resilience is provided, the difference between Risk and Resilience is highlighted and a general overview to facilitate the incorporation of Resilience into transportation assets and the corresponding strategies to improve resilience are presented.
