摘　　要：元胞自动机的交通流模型以简单的规则反映交通过程中实际存在的各种复杂因素,并能在计算机上方便实现,从而可以演示这些因素对城市交通系统动态特性的影响。本文系统阐述了元胞自动机在交通流上的应用,以元胞自动机理论为基础,把车辆在路段上运动的变化规律表述为元胞自动机的演化规则,建立了基于元胞自动机理论的交通流模拟的NS模型,并利用Matlab语言实现了带信号灯控制的一维元胞自动机模型的仿真。The Cellular Automata traffic stream model can reflect various complicated factors existing in traffic process with a simple rule, and also can be realized with computer, thus it can illustrate the effect of factors on the urban traffic behavior conveniently. This paper systematically introduces the application of the models and the theories of the cellular automata theory for the traffic stream models, and describes the moving character of vehicles as changing rules of cellular automata. One simulating program with language is written, it is mainly used to apply to the research of one lane Cellular Automata controlled by traffic light.
