摘要
群体疏散正日益变得频繁。为了有助于学者与业界应用和研究群体疏散,研究基于当前最新最全的成果,将用于群体疏散的主要数字仿真方法进行整理归纳。通过比较分析认为:元胞自动机模型及格子气模型在时空方面都是离散的,具有很高的计算效率;社会力模型及流体动力学模型在时空方面都是连续的,前者适合描述复杂的群体行为,后者适合描述高密度的群体行为;与前四种模型相比,基于agent模型计算效率最低,但它很容易模拟不同类型的个体(或群体)。基于现有这些仿真方法的研究成果,未来的研究趋势将着眼于多种仿真方法的组合应用,并在仿真中充分考虑个体差异特性。尤其是在模型中增加行人的社会心理因素和基于agent的仿真,将是今后描述疏散群体复杂行为的一种主流方法。
