In order to obtain basic knowledge to develop a method of demand forecasting by means of transportation for long distance evacuation which may extend to the next prefecture, we conducted two questionnaire surveys- one of which was on the Civilian Protection division of the 47 prefectures of Japan, and the other was targeting the citizens in the four prefectures of Fukushima, Niigata, Fukui and Shizuoka. Based on the obtained data, we grasped the present situation of preparing for the evacuation as a measure of Civilian Protection in the prefectures, and analyzed the influence factors in citizens' choices of means of transportation for the evacuation. Then, we corrected the ratio of the choices by using existing statistical data such as the national census data.
