Description

 This study aims to elucidate the characteristics of evacuees' movements on the staircase of a high-rise building, such as the flow rate, walking speed, evacuee density, and merging ratio at the staircase landing, for evacuation planning, evacuation calculation, and computer simulation on the basis of observational data of a total evacuation drill.<br> The characteristics of the walking and merging behaviors of occupants of a high-rise building descending to the staircase were investigated on the basis of observational data of a real total evacuation drill conducted in a high-rise building in Tokyo. The results are expected to be useful for developing and validating simulations by a computer model as well as evacuation calculations.
