Speed Limit Sign Custom Traffic Speed Sign On Road Speed Control Sign

There are two types of road signs:

(1) For fixed, a figure represents a content, and fixed in a position, called fixed.

(2) Variable type, mostly used on expressways, such as variable speed sign board, generally presents a circle, which can display different speeds as required, such as 120, 100, 80, 60 (km / h), etc ; there are also variable content sign boards, according to some commonly used contents prepared in advance, such as rainy and foggy weather, driving slowly; construction ahead, pay attention to safe driving; welcome to Χ expressway; welcome to visit leaders. Generally, it is fixed on a certain position or overpass by frame, and displayed by the central monitoring room in time according to the required content. The visibility of the signboard is clear within 300-400M when driving at night.

Variable sign board is usually made of light-emitting diodes. Recently, there are optical fiber products. This kind of character brightness display is even, and the font is not complete due to the damage of diodes. It can also easily adjust the light-emitting brightness to adapt to different external environment, and make full use of the light source, reduce the advantages of energy consumption (Guangzhou Shenzhen Expressway).

The size of signboards has specific requirements in the international GB "technical code for road signs and markings"

Generally, the board surface is circular and rectangular, because the driver must see it within a certain distance of 300-500m during the driving of the vehicle on the highway, so as to react. In addition, in rainy and foggy weather, the visibility is poor. For the sake of safety, the size and font size of the sign board are increasing through practice.

For example, in the past, the diameter of prohibition signs was usually 40-60cm, but now it has been increased to 100-120cm.
