教室内行人疏散的元胞自动机模拟研究

针对具有两个出口并由桌椅构成多条通道的教室建立了行人疏散的元胞自动机模型,进行计算机模拟的结果表明：行人根据到出口的距离和行人拥挤程度两个因素来选择出口和目标网格能缩短疏散时间;出口的宽度对疏散过程有一定的影响,但随着出口宽度的增大,对疏散的影响越来越小。

Simulation of Cellular Automaton with the Evacuation in a Classroom

In view of a classroom with two exits and many channels constituted by desks and chairs,the cellular automaton model of the passer-by evacuation is established.Computer simulation results show that the evacuation time becomes less when passers-by take such two factors into account as the choices of exits and channels according to the distance to the exit and crowding condition,and that the exit width has a certain impact on the evacuation process,whereas the impact will become less and less with the increase of the exit width.
