人群聚集活动越来越多地出现在各种公共场合,而由此引发的各种安全问题也逐渐受到社会各界的重视。在重要建筑和人群密集场所突发重大恐怖事件时,将人员在较短的时间内紧急疏散至安全地带是恐怖事件紧急救援的首要任务。文中提出一种基于LBM的高效的人群疏散算法及模型,该模型将Lattice Boltzmann Method的D2Q9模型应用于人流疏散的模拟过程。该模型的着重点在于研究人群的疏散过程,从人流整体的运动特点考虑疏散问题。针对大规模人群紧急疏散的模拟,可比较精确地预测人流紧急疏散的过程与现象

Crowd gathering activity is more and more common in various public places,which triggers security issue,it is getting great attention from all society.In the case of emergency,evacuating the people in short time is the most important thing.An efficient model of evacuation can be presented based on LBM,this model applies Lattice Boltzmann Method D2Q9 model to the simulation of flow evacuation.The model resolves the evacuation problem from the features of the whole flow,focusing on researching the process of flow evacuation.This model can forecast the process and phenomenon of flow evacuation for the large-scale evacuation
