在发生灾害时，为了最大限度地减少受害者人数，迅速疏散到疏散地点非常重要。然而，由于在灾害发生之前仅提供关于疏散地点的位置的信息，因此在灾害发生时，在各个地方的人们将不确定他们应该单独采取的疏散路线。因此，需要一种用于根据疏散地点的位置的状态、无法通行的路段的位置以及由大量疏散者引起的拥堵来快速确定疏散路线并引导人们的方法。然而，在诸如灾区的恶劣通信环境中，由于信息分发非常困难并且延迟是不可避免的，因此用于确定疏散路线的方法必须考虑信息分发中的延迟。在本文中，我们提出了一种方法，确定疏散引导路线，考虑到延迟发生在信息分发，我们评估的影响，疏散引导和所提出的方法的性能，通过仿真。
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.
