交通流中存在着高吞吐量的亚稳态和滞后效应，这是众所周知的事实，简单的交通流元胞自动机模型及其连续推广无法再现。结果表明，该模型可以推广到一个单参数的家庭的模型，其中一部分再现亚稳态和滞后。具有该属性的模型和不具有该属性的模型被可以清楚地识别的过渡分开。
It is a well known fact that metastable states of very high throughput and hysteresis effects exist in traffic flow, which the simple cellular automaton model of traffic flow and its continuous generalization fail to reproduce. It is shown that the model can be generalized to give a one-parametric family of models, a part of which reproduces the metastable states and the hysteresis. The models that have that property and those that do not that are separated by a transition that can be clearly identified.
