A Study on Human Behavior of a Crowd in a Staircase Based on the Evacuation Simulation Model

Authors are developing an evacuation model, grasping gradually the results obtained from the evacuation simulation model. The fundamental consideration for the evacuation guiding method in a high-rise building was carried out by the developing model in past research [1]. When the number of evacuees in a stair case increased in the developing model, it was founded that the crowd density in a stair case became about 5.0 persons/m2. It was probably caused by the inaccurate modeling for the tread of stairs in stair cases. Therefore, this paper reports the simulation results by the improved model that included the influence of the tread of stairs.
