| 内容記述 | Nowadays, various natural disasters have caused tremendous damages to Japan. It is necessary not only to take disaster prevention and mitigation measures to take appropriate evacuation actions in the event of a disaster and minimize human damage but also to discuss the provision of the information for quick recovery and relief activities after a disaster. In this study, the evacuation simulation considering the flooding state by a storm surge on the basis of the result of flooding analysis is conducted so as to grasp the proper evacuation behavior when a storm surge occurs. Many agents get caught in the flooding in front of the evacuation site and cannot complete evacuation when there is an evacuation spot in a low-altitude area or an area prone to flooding. Next, the additional evacuation simulation in which the agent grasps the flooding state beforehand is carried out under the same conditions as those used in the analysis in which the agent doesn’t grasp the flooding state in advance so as to understand the effect of grasping the inundation place beforehand on the evacuation action. When the agent grasped the flooded state in advance, they can complete the evacuation in a short time without being caught in the flooding. At the same time, the evacuation completion rate is much higher than that in the case where the flooded state is not grasped in advance. The damage situation on the road is extracted using SAR image and road edge data in order to grasp the damaged area on the road necessary for a smooth recovery and relief activities after the disaster since the purpose of this study is not only to provide the useful information on disaster mitigation measures, but also to promptly grasp the disaster area immediately after a disaster and to provide the information of leading to more rational recovery activities. As the results of grasping the disaster situation using SAR images, it is found that the extensive changes such as flooded areas can be extract by the method of additive color mixture used in this study. | |||||||||||

| 内容記述 | The results of flooding analysis and evacuation simulation can be utilized for the improvement of the usefulness of the hazard map, the utilization for disaster prevention education, and the disaster-resistant city development planning. In addition, the results of the satellite image analysis are possible to be important information for quick recovery activities by utilizing it to grasp the damage situation of the road area in the event of a disaster Based on the above, it becomes possible to consider the disaster reduction and recovery measures in large-scale cities, which cannot be grasped by experiments. | |||||||||||
