ABSTRACT
In case of a disaster, it is important to notify information on disasters and evacuation to residents quickly and accurately to encourage evacuation. In this paper, we propose a disaster evacuation support system considering user's situation based on open data. When a disaster occurs, the system detects whether the user’s location is in a dangerous area or not, the user is approaching the dangerous area or not. Then the system notifies and provides evacuation direction to the user. Moreover, the system also supports a rescue function to share rescue information to neighborhood people automatically. We conducted a verification experiment, and the results of the experiment verify the usefulness of the proposed system.
