Abstract

The purpose of this study is to obtain basic data for disaster prevention. We investigated the effects of snow on evacuation facilities and evacuation activities. The results of the field surveys showed that the steps leading to the outdoor evacuation sites could not be used due to the snow. The doors at the emergency exits could not be used either they opened outwards and were blocked by snow. Estimations of evacuation time under the conditions of snow on the ground showed that appropriate maintenance of the evacuation route is needed to ensure that an adequate walking speed can be maintained to the evacuation site. Snowfall regions must take their own countermeasures, such as establishing the different evacuation sites in summer and winter.
