With the increasing demand of traffic flow simulation and the development of ITS, the traffic flow model based on cellular automata is developed. The problem of traffic flow model is an important part in the research of traffic flow theory. The emergence of traffic flow cellular automata brings us a new method for the research of traffic flow theory. This paper mainly introduces one lane traffic flow cellular automation models, and proposed a prospect about the development of cellular automation models.% 随着交通流模拟的需要及智能交通系统的发展,出现了基于元胞自动机理论的交通流模型。交通流模型是交通理论研究的重要问题,交通流元胞自动机模型的出现和发展为交通流理论的研究提供了一种新的方向。文章主要介绍了单车道交通流元胞自动机模型,并对元胞自动机模型的发展提出了展望。
