本文提出了单车道交通流的元胞自动机模型。汽车速度的更新规则不仅取决于本车和前车的位置，而且还取决于两辆汽车的速度。利用计算机模拟，我们得到了一些基本的定性结果和所提出的模型的基本图。与文献中已有的模型进行了比较。我们发现，所提出的模型的基本图是更符合在真实的交通测量的结果。并且该模型能够再现真实的交通流中发现的、但现有模型无法预测的一些相关宏观状态。
In this paper we present a cellular automata model for one-lane traffic flow. The update rules of velocity of a car depend not only on the positions of this car and the car ahead of it. but also on the velocities of the two cars. Using computer simulations we obtain some basic qualitative results and the fundamental diagram of the proposed model. In comparison with those of the existing models in the literature. we find that the fundamental diagram of the proposed model is more consistent with the results measured in the real traffic. and the model is able to reproduce some relevant macroscopic states that are found in the real traffic flow but cannot be predicted by the existing models.
