Abstract
The massive tsunami generated by East Japan great earthquake disaster brought serious damage in the Pacific coastal area of the Tohoku district. As the results, is becomes clear that evacuation using car is not always safer evacuation method against tsunami. Horikiri district of Tahara city in Aichi prefecture was focused on in this study. Because it was estimated that a tsunami with 1 meter height will attack this district within 12 minutes after the occurrence of Nankai trough earthquake and the residents in this district are needed to execute quick evacuation. The evacuation simulation was executed to evaluate several scenarios of evacuation condition where the share of the evacuation method was altered. As a result of this study, it becomes clear that the excessive car evacuees make the evacuation in this district less safe and that the increase of bicycle evacuees makes it safer.
