Abstract: It is very important to evacuate quickly to evacuation sites in order to minimize the number of victims in the event of a disaster. However, since only information about the locations of evacuation sites is presented before a disaster, in the event of a disaster, people present at various places will not be sure about the evacuation routes that they should take individually. Accordingly, there is a need for a method for quickly determining evacuation routes and guiding people in accordance with the status of the locations of evacuation sites, the location of impassable road section, and the congestion caused by vast number of evacuees. However, in poor communication environments such as disaster area, since information distribution is very difficult and delays are inevitable, a method for determining evacuation routes must consider delays in information distribution. In this paper, we propose a method of determining evacuation guidance routes in consideration of delays that occur in information distribution, and we evaluates the influence of the delays on evacuation guidance and the performance of the proposed method through simulation.
