ln this study, two analyses of road network capacity in the case of inundation in the north part of Sapporo City are carried out. That is, changes of road network capacity caused by both the cut off of road sections caused by inland water inundation and the traffic measures that prevent links from being cut off are examined. As the results. the following two conclusions are obtained. I) The network capacity in the case of the flood decreases 32% compared with that in usual status. II) Because the traffic measure made to a road section has additive, alternative or synereistic effect each other, it is important to consider the interaction between road sections in examining the effect of traffic measures. lf traffic measures are made to three of links cut off in the case of inundation, the increases of network capacity vary from 2% to 38% compared with the network capacity when no traffic measure is made.
