We focused on road users' evacuation of when the Nankai Trough huge earthquake occurs and analyzed the relationship among individual attributes, understandings of disaster, prior information for tsunami disaster and evacuation behaviors by using questionnaire survey data. From the results of analyses of covariance structure for coastal road users' consciousness and behaviors, it is revealed that the prior information conjures up tsunami disaster in their minds but prompts their speedy evacuation behaviors by car. It is also found that the persons, who have many knowledge of weather warning and evacuation information or live in the area affected by an earthquake and tsunami disaster, tend to evacuate promptly in spite of the presence or absence of priori information while the persons who live in inland and safe area but become potential coastal tourists aren't tend to evaluate quickly. Thus, it is necessary to provide the information not only for the knowledge of disaster but also for promoting evacuation behavior by foot to potential coastal tourists in order to avoid the tsunami disaster risk.
