Description

While agent simulation has been used to investigate evacuation scenarios, evacuation speed of frail elderly has not been fully studied yet. Therefore, in order to obtain the evacuation speed of the frail elderly we recorded videos of evacuation drills held in a group home with care. We analyzed evacuation steps in detail through the videos and acquired the evacuation speed of the frail elderly. We also simulated the evacuation drills with an agent model using the observed data. In the simulation result, the evacuation completion time was about 10% faster than the measured time of the evacuation drills. The difference in evacuation completion time can be explained considering the time taken for “unplanned behavior” of caregivers such as stopping to think about the next action.
