Abstract: In this paper, a cellular-automatic model is presented in order to imitate the dense crowd ambulation in a limited space. The characteristic features of this model have two: adoption of object-oriented technique(OOT), which makes model full of applicability, extensibility and reusable; and conception of “cellular-automatic control blocks (CACB)” based on requirement from reality of application, which facilitates practicality. The simulating experiments given here show the good ability for imitating the ambulation of a complicated dense crowed, and prospects of application in the near future.

摘要： 为了模拟在有限空间中大量人员的流动分布，基于面向对象技术，在已有交通流模型和行人流模型的基础上，建立了一个在有限空间内高密度人群流动的元胞自动机模型。采用面向对象思想的建模方法，使得模型具有很好的适用性、扩展性和复用性。并根据出现高密度人群的一般情况和控制对象的需求，提出“元胞控制块”的概念，使整个模型架构具有很强的应用转化能力。计算机模拟验证的结果良好，充分显示了元胞自动机模型对复杂人群流动的模拟能力。
