Description :

　　Guocheng traffic signs have made significant contributions to people's lives. The height of a traffic sign refers to the vertical distance from the lower edge of the sign to the road surface. The unreasonable height setting of traffic signs can also bring inconvenience to our lives. Previously, there were news reports that 1.4m signs often caused injuries to pedestrians. What are the requirements for setting the height of traffic signs? 1. The sign installed on the shoulder should have a height of 1.8-2.5m from the lower edge of the road surface. In special circumstances, such as obstruction in the line of sight, it can be appropriately increased. The outer edge of the sign board should not be less than 30cm from the road measurement solid line or shoulder edge. 2. When there is a curb, drainage ditch, or sidewalk on the road, or when there may be parking or walking, the minimum height from the lower edge of the sign to the sidewalk or shoulder is 2.1m. The sign pole is exposed to sunlight and rain every day, and graffiti and even small advertisements are posted on the sign pole, which not only seriously damages its aesthetics, but also easily causes surface damage to the sign pole, leading to rust and shortening its service life. With the advancement of technology, traffic signs have undergone significant changes in their appearance design compared to previous signs, which can also contribute to urban construction. The current design of traffic signs will be even more unique, with various shapes and innovative designs, which is only the advantage demonstrated by their exterior design. There are also many characteristics of the "interior" of traffic signs, such as good weather resistance, strong stability, and good earthquake resistance. This also makes traffic sign poles longer in use.
