Velocity and transportation ability of vulnerable people during a community tsunami evacuation drill: Outdoor evacuation using a rollator, transport chair, wheelchair, and cart in Shinyo Bokomi, Kobe, Japan

摘要

Abstract In this study, a method is established for planning the practical evacuations of residential areas. The emergency workers and caregivers in a community may use various instruments to transport vulnerable people while evacuating during a tsunami to minimize the number of fatalities. An evacuation drill was conducted in Shinyo Bokomi, Kobe, Japan, by simulating the occurrence of a tsunami. During this drill, the evacuation volunteers evacuated vulnerable persons to a safe destination using rollators, transport chairs, wheelchairs, or carts. Furthermore, all evacuation trials were completed before the estimated tsunami impact time. This study quantitatively analyzed the capacity and quantity of the evacuation transportation. The average evacuation transportation capacities of the rollators, transport chairs, wheelchairs, and carts were 3.7 persons/km/h, 5.1 persons/km/h, 5.4 persons/km/h, and 4.6 persons/km/h, respectively. The debriefing meetings following the drills suggested that the written rescue instructions worked effectively in the drill. We recommend that communities incorporate the usage of such instruments into their evacuation plans and implement the same in their tsunami response.
