Incorporating Resilience in Infrastructure Prioritization - Application to Japan’s Road Transport Sector

Loss of Functionality (ALF) may be considered in isolation to better understand the ‘resilience’ of road projects. In this case, the question at hand is how much functionality various proposed projects will lose in the event of a disaster. On the other hand, if projects are pursued specifically to improve a region’s overall resilience, a more important metric would be an ALF variation (ΔALF) that measures a project’s impact on the overall road system.
