提出描述交通灯控制下城市道路交通流动力学演化过程的元胞自动机模型，其中交通灯对于路段上车辆的影响是全局的，驾驶员可根据交通灯的状态及时调整驾驶行为，同时还考虑前方车辆的预期运动.该模型中车辆的运动更加平滑，符合实际交通现象.应用模型中的驾驶策略，可以有效地减少怠速和速度骤减的状态，从而减少机动车的尾气排放.

A cellular automaton model is proposed to depict dynamical evolution of urban traffic flow under control of traffic lights on a single-lane road. It is assumed that traffic lights have global influence on vehicles, and drivers adjust their behaviors timely according to the states of traffic light. Furthermore, anticipation effect is taken into account to predict the movement of vehicles in the presence of traffic lights. Therefore vehicles can move forward more smoothly. This is in agreement with the actual situation. It is expected that using the proposed strategy in driving can help reduce vehicle idling and abrupt deceleration and lead to less emission of exhausted gas.
