| Abstract |
Research on the walking speed, which was critical factor for evacuation calculation and plan when forming crowd, derived the following regression equations: for horizon and for vertical(going up). Horizontal crowd walking speed had declining slope close to the result of MAEDA; a stay especially appeared in the crowd of 4[person/m2] or more. Therefore, to plan efficient evacuation plan, a crowd of 4[person/m2] or less should be allowed and plans for adding or revising evacuation capacity were required. In case of vertical, the result was lower than existing vertical (going down) walking speed of 0.5[m/s]; thus, examination on each factor should be conducted thoroughly in the course of research on going-up at building of large-scale. |
