设计一个交通灯：
初始四个方向的红灯全亮。延时1秒。
东西方向绿灯亮，南北方向红灯亮。延时5秒。
东西方向黄灯闪，南北方向红灯亮。延时2秒。
东西方向红灯亮，南北方向绿灯亮。延时5秒。
东西方向红灯闪，南北方向黄灯闪。延时2秒。
返回2，继续运行。
紧急情况时手动控制四个方向红灯全亮。之后返回打断时的状态继续。-The design of a traffic light: all bright red light of the initial four directions. Delay of one second. Green light east-west direction, the north-south direction the red light. Delay of 5 seconds. East-west direction flashing yellow light, the north-south direction the red light. Delay 2 seconds. Something the direction red light green light, the north-south direction. Delay of 5 seconds. East-west direction the red light flash flashing yellow light, the north-south direction. Delay 2 seconds. Back 2, continues to run. Emergency manual control four red lights all bright direction. After the return state when the interrupt is continued.
