中文说明：元胞自动机不同于一般的动力学模型，元胞自动机不是由严格定义的物理方程或函数确定，而是用一系列模型构造的规则构成。凡是满足这些规则的模型都可以算作是元胞自动机模型。因此，元胞自动机是一类模型的总称，或者说是一个方法框架。其特点是时间、空间、状态都离散，每个变量只取有限多个状态，且其状态改变的规则在时间和空间上都是局部的。用于模拟交通状况。
English Description：
Cellular automata is different from general dynamic models. It is not determined by strictly defined physical equations or functions, but by a series of rules constructed by models. Any model satisfying these rules can be regarded as cellular automata model. Therefore, cellular automata is the general term of a class of models, or a method framework. Its characteristic is that time, space and state are discrete, each variable only takes a limited number of States, and the rules of state change are local in time and space. Used to simulate traffic conditions.
