Abstract
A large-scale disaster causes widespread road closures, which can delay recovery work in the devastated area. To minimize the impact, it is essential to immediately recover the road that connect the devastated areas to other parts. Since the Great East Japan earthquake in 2011, the issue was recognized to be urgent, and a road recovery plan for disaster mitigation has consequently been of great interest in Japan. This study proposes an accessibility-based model that can select a prioritized road considering the level of the disaster and recovery capacity. The model was implemented in Shikoku area, Japan. Result showed that proposed model can discover a feasible road recover pattern by solely inputting recovery work after a disaster.
