公路上的安全岛的作用主要是提供一个相对安全的空间。收费站、城市道路的交通岗亭、距离公路较近的公共设施，都有可能修建安全岛。
The main function of the safety island on the highway is to provide a relatively safe space. Toll stations, traffic posts on urban roads and public facilities close to roads may all build safety islands.
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"州苗木  保定电动门 保定空压机 化粪池模具 微型蠕动泵 保定强夯 收费岛模具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 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.
