In this study, authors investigated means of transportation and benefit of bicycle usage for tsunami evacuation drill in Tahara city facing the high threat of Nankai Trough earthquake. According to the questionnaire survey, 45% of people evacuating longer distance destination (Atsumi Sports Park) used bicycles, and percentage of cases finishing within 15 minutes target time is higher. According to the time measurement at safety line, delay time of bicycle users is shorter than pedestrians. GPS log recordings indicated average velocities of 91m/min for pedestrians and 146m/min for bicycles, and standard deviation is smaller for bicycles than for pedestrians. Identifying contour polygon for 5 min., 10 min. and 15 min. allowance time for evacuation, bicycles are effective to cover wider communities where evacuation destination is more than 1km and rather distant.
