安全岛是一种安装在斑马线上的安全装置，与斑马线长度相当，两端还各竖有一根“反光警示桩”，夜间在车灯的照耀下会发出亮光，以提醒司机注意避让。设立“安全岛”是为了让人们养成“二次过街”的习惯，即在第一次绿灯时间，先到达道路中央的“行人安全岛”，第二次绿灯亮起再走剩下的路程。
The safety island is a kind of safety device installed on the zebra crossing, which is equivalent to the length of the zebra crossing. There is also a "reflective warning post" at both ends, which will light up under the light of the lights at night to remind the driver to avoid. The purpose of setting up "safety island" is to make people form the habit of "crossing the street twice", that is, to reach the "pedestrian safety island" in the middle of the road at the first green light, and then walk the rest of the way when the second green light is on
