Evacuation and Crowd Dynamics

The specific flow of the egress paths and the walking speed of the people are the key factors for the evacuation time prediction under emergency conditions. The research works on the movement behavior along the level paths and stairs are reviewed in this paper,and the evacuation time from a high-rise building predicted by different research models are compared. It is found that large differences of the movement speeds exist under the free walking and higher-density movement conditions. For the level surfaces,the results are almost same,when the crowd density is in the range of 0. 5 person /m2 D 2. 5person /m2. However,for the walking upstairs,due to so many influence factors,the existing models are so different.
