东西向绿灯亮 5s 后，黄灯闪烁，闪烁5 次亮红灯，

红灯亮后，南北向由红灯变成绿灯，5s 后南北向黄灯闪烁，

闪烁5 次后亮红灯，东西向绿灯亮，如此往复-East-west green light 5s after the flashing yellow light flashes 5 times red.

Red light, north and south from the red to green, 5s after the north and south to the flashing yellow light.

Red light flashes 5 times from east to west to the green light, and so forth
