In Theme 7-2 of SIP Disaster Prevention (Enhancement of Social Resiliency against Natural Disaster of Cross-ministerial Strategic Innovation Promotion Program), we implemented the two subthemes to develop the disaster response and mitigation technology effective for the complex disaster caused by earthquake and flood by torrential rain in megalopolis such as Tokyo metropolitan area; “Subtheme 1: Development of Application Software for Supporting All-Hazards Management in Megalopolis and Commercial Areas around Large Terminal Stations,” and “Subtheme 2: Sustainable Development of Local Disaster Prevention Technology with Visualization Application.” In the former, we formulated behavioral guidelines of central city areas during disasters based on the hazard/risk assessment, and developed an application software for PC/smartphone to support emergency management by delivering relevant information to civilians and disaster response workers during the disaster. Especially, the application would reduce secondary disasters, such as the confusion/panic by the huge number of crowds. In the latter, to “efficiently utilize the limited time, human resources and goods and to minimize damage” at the time of the disaster, we developed a “travel support application,” which can efficaciously “assign” workers to various tasks (the events that require a response) that are spatially distributed at the occurrence of disaster, “navigate” by identifying optimal routes for patrol and “monitor” progress.
