Abstract
Highway networks were blocked by such damage as bumps induced by earthquakes. To reopen the blocked roads rapidly, it's necessary to repair them rapidly and effectively considering the traffic performance of roads. In this study, driving tests using three types of vehicles running through bumps made artificially on the test road have been conducted. Considering the actual road management and based on the driving test results, the relationship between bump levels and velocity of vehicles running through bumps considering the types of vehicles are clarified quantitatively and proposed for the performance-based road management just after an earthquake.
