[en] 'Drill of evacuation with family car', 'Drill of evacuation for the disabled with family car', and 'Evacuation drill from the large enclosure' had been conducted in the National Comprehensive Nuclear Disaster Exercise which was taken place on December 21st and 22nd, 2009 in Ibaraki Prefecture. This work evaluated the dynamic traffic flow of evacuees' cars during the evacuation drill using three kinds of data, i.e. questionnaire for the participants in the evacuation drill, GPS tracking data of vehicles of evacuees, and photographies shot from the air and ground. The fluctuations of traffic volume influenced by traffic and access controls for the outside of evacuation zone were evaluated using the traffic volume data which were provided by Ibaraki prefecture. The opinion survey was also conducted to participants of evacuation drill for three purposes, i.e. to get the data of choice of measures for evacuation, to find out problems in evacuation for the disabled, to find out problems in evacuation from the large enclosure. The analysis of the dynamic traffic flow of the vehicles of the evacuees showed the traffic controls for evacuation routes are very effective. The analysis of the traffic volume showed the necessity of traffic controls for the outside of evacuation zone for control traffic congestion. The opinion surveys revealed the following important outcomes on 'evacuation by family car': -Sixty five percent of the participants chose 'evacuation by car', and over seventy percent of them answered 'the easiness of the move after arrived at the reception center' and 'less long walking distance to the bus stop' as reason. -To make evacuation for the disabled smoothly, the helpers of evacuation for the disabled wanted the arrangement to know the location and the kind of impediment of the disabled and the training to help the disabled in the normal situation. -To make evacuation from the large enclosure smoothly, the test of the alerting and noticing system for visitors of the enclosure is very important, and the guide by stuff of the large enclosure and the notice board are needed.
