摘　　要：利用元胞自动机模型,采用双向运行规则模拟城市交通,发现存在五种稳定状态:①在每个时间步,所有箭头都能运动;②箭头不保证每时都能运动,但不存在永远不动的箭头;③有一部分箭头永远被阻塞而另一部分箭头每时都能运动;④有一部分箭头永远被阻塞而另一部分箭头都能运动但不保证每时都能运动;⑤所有箭头永远被阻塞.对此进行了分析讨论.In this paper, a cellular automata is used to simulate the bidirectional transportation, and five stable states are found:all arrows move during all time steps; all arrows are movable, and some arrows move but the others arrows are blocked in some time steps; some arrows are blocked but the others arrows move during all time steps; some arrows are blocked during all time steps but the others arrows are movable, and some arrows move but the others arrow's stop in some time steps; and all arrows are blocked during all time steps.
