Evacuation motion simulation using 3D kinematic digital human models (KDH) considering experimental verification assuming tsunami struck is addressed. Representative patient transportation motions have been experimentally investigated and effectively utilized for KDH data calibration of accurate evacuation simulations. The patient transportation speed as well as the intermittent halt time on flat ground is significantly affected by the load of the transporters. As for the stairway going-up evacuation, the transit speed decreases from pack-strap carry two-person arm carry and slightly wounded walking in order. Several evacuee motion primitives have been developed using KDH for stairway going-up simulation assuming the evacuation to a tsunami evacuation tower. The experimental result such as walking as well as the transportation speed was introduced into the evacuation simulation as calibration data. The simulation results show that the evacuation time is affected by the number of evacuees or the congestion due to the patient transportation. The developed simulation techniques can be effectively utilized for the planning of tsunami tower evacuation and related crowd behavior prediction.
