In this paper, a Monte Carlo simulation method, which is able to evaluate practically the post-earthquake restoration process of road transportation system, is proposed. The simulation model is divided into three phases ; 1) Assessment of damage state of network, 2)Performance evaluation of system included intraffic flow analysis, and 3) Recovery process of damaged network. The restoration problem is separated in two parts, emergency restoration evaluated by considering only connectivity between nodes, and rehabilitation works affected by traffic control. The structural and functional restoration are defined by various useful measures. The present method is then applied to evaluate the performance of road transportation system in the Izu Peninsula during the post-earth ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF - ‹æ•ª @@@@˜_•¶W
