A Proposal and its Effectivity of a Tsunami Evacuation Guidance System Considering Visitors’ Preference

抄録

To develop tsunami evacuation guidance system can be effective for tourists visiting towns that have risks of tsunami. This paper aims to propose a guidance system that can reflect visitors’ preference of evacuation route choice. First we investigated visitors’preference by web questionnaire survey to establish a visitors’ evacuation route choice model. The respondents tended to choose higher grounds rather than evacuation towers and to preferred wider roads for evacuation routes. We found that evacuation direction, required time for evacuation, crowdedness of evacuation places were also essential factors. Second, web application was developed to reflect the model. Finally, we conducted an experiment to verify the effectivity of the application in a town and twenty students participated in the experiment. As a result, we partially verified the effectivity of the application developed and we exacted other factors that should be included in the system in the future.
