To prepare evacuation plans, including an evacuation support system for vulnerable people such as the elderly, injured, pregnant, or other people requiring support during a tsunami evacuation, validating evacuation drills with respect to real-world circumstances using quantitative data is important. This study aims to clarify the importance of using evacuation drill data for evacuation planning. To this end, we measured the movements of residents during an evacuation drill conducted according to a set plan in a community and verified the observed quantitative data. We have been supporting the drills and community disaster management plan (CDMP) in the Shinyo Community of Kobe City since 2008 and hence selected this community for our study. We measured the residents’ evacuation time and speed using various transportation modes to transport vulnerable people to safety during the drill and verified the evacuation plan’s effectiveness. Quantitative data were verified in the drills and vulnerable people and their supporters, who were measured on this occasion, were evacuated from the tsunami warning area within the estimated tsunami hitting time for Hyogo prefecture of 90 min after the earthquake. Further, using four types of transportation modes—a rollator (wheeled walking aid), transport chair, wheelchair, and cart—yielded conveyance speeds (average of the time taken by a vehicle to traverse the entire evacuation route, excluding wait times at traffic signals) of 1.03, 1.42, 1.50, and 1.27 m/s, respectively. Few days later, the participants provided feedback on the drills in an evaluation meeting and deemed the evacuation plan effective. This study presents a progressive thought process that utilizes the interaction between “planning” and “training” to enable a feasible CDMP to combat disasters.
