近几年来，城市交通护栏有了长足的发展，并在城市交通秩序改善和文明交通行为方面发挥了非常重要的作用。总体上讲，护栏越来越美观大方，其作用越来越明显。
In recent years, urban traffic guardrail has made great progress, and has played a very important role in improving urban traffic order and civilized traffic behavior. Generally speaking, the guardrail is more and more beautiful and generous, and its role is more and more obvious.
但是，由于目前还没有护栏设计、设置规范，还没有护栏技术标准，因此各城市的交通护栏种类较多，良莠不齐，在选材、结构、强度、颜色、表面处理等方面随意性大、五花八门，往往重视某一方面，又忽视另一方面的作用。
However, because there is no design and setting criteria for barriers, and there is no technical standard for barriers, there are many types of traffic barriers in different cities, which are arbitrary in material selection, structure, strength, color, surface treatment and so on. They often attach importance to one aspect while neglecting the other.
