说明：  位于十字路口的交通灯，在A方向和B方向各有红，黄，绿三盏灯，按下表所列顺序进行循环。其中1表示灯亮，0表示灯灭。实验中假设交通灯按照10s的节拍工作，各个灯亮的时间相等。
(Traffic lights at crossroads, in the A direction and B direction of each of red, yellow, and green light to cycle the order listed in the table below. Where 1 is light, 0 for OFF. Assuming the experiment by 10s beat traffic lights work, all the time lights are equal.)
