（1） 在十字路口的两个方向上各设一组红、绿、黄灯，显示顺序依次为红灯-绿灯-黄灯-红灯。 南北方向和东西方向红灯绿灯相反。南北方向红灯显示时间为东西方向黄绿灯显示时间的总和，同理，东西方向红灯显示时间为南北方向黄绿灯显示时间的总和。
（2） 设置一组数码管，以倒计时的方式显示允许通行或禁止通行的时间，其中绿灯、黄灯、 红灯的持续时间分别是7s、2s和9s。
-(1) a set of red, green and yellow lights are arranged in each of the two directions of the intersection. North-south direction and east-west direction of traffic lights opposite. North and south direction of the red light shows the sum of the time for the east-west direction of the traffic light display time, the same thing, the direction of the red light to show the north and south direction of the green light to display the total time.
(2) to set up a set of digital tube, in order to display the countdown to allow passage or prohibit the passage of time, where the green light, yellow light, red light duration are 7S, 2S and 9s.
