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。目前，"二次过街"的方式已在欧洲各国广泛应用，上海、郑州等城市也从前几年开始推广。 这一做法大大增加了行人过马路的安全性，避免了"急行军"，尤其保护了老人、小孩和残疾人的利益。
The safety island is a safety device installed on the zebra crossing, which is equivalent to the length of the zebra crossing. A "reflective warning post" is also erected at both ends. At night, it will emit light under the light of the lamp to remind the driver to avoid. The "safety island" is set up to let people form the habit of "crossing the street twice", that is, at the first green light time, first reach the "pedestrian safety island" in the middle of the road, and then go the rest of the way when the second green light is on. At present, the "second crossing" method has been widely used in European countries, and Shanghai, Zhengzhou and other cities have begun to promote it in the past few years. This practice greatly increases the safety of pedestrians crossing the road, avoids the "rush army", and especially protects the interests of the elderly, children and the disabled.
