Abstract
The flowout coefficients of the crowd movement through doors and corridors that we are using in the fire safety design of buildings were measured over 30 years ago. We measured the flowout coefficients of getting commuters off the trains and down the stair at the terminal station and leaving visitors from the theaters and movie theaters by use of the video tape recorder to get the recent data. The following results which measured at the passage through the door and the landing (at the entrance of stairs) were obtained: (1) the coefficient of the passing people were increased in proportion to the increase of the number of people who were waiting to pass: (2) the flowout coefficient greater than that of the conventional value: (3) the number of passing people didn't increase in proportion to the door and landing width, but step-wise under the condition of less than 2 meters in the width: (4) the flowout efficient at both the door and the landing was increased in proportion to the accumulating people in the queue, as increase the people, the flowout coefficient was saturated.
