Experimental Study on One-Dimensional Movement with Different Motion Postures

摘要

The motion postures of pedestrians influence the evacuation efficiency in fire and smoke filling buildings. In a building fire, the effective method is to lower the height of mouth and noise to avoid the harm to occupant's health. In this paper, we conduct the one-dimensional pedestrian movement experiment to study the movement characteristics with different motion postures. Firstly, it is observed that the speed of upright walking is the fastest, and the slowest speed is low crawling. However, there is no significant difference in speed between upright walking and walking with a stoop. Through this experiment, the basic speeds of different motion postures can be obtained, which can be used to collect the basic data for evacuation simulation in fire and smoke buildings. These findings can provide insight to evacuation strategy when building fire occurred.
