[0002] Traffic signs are road facilities that use words or symbols to convey guidance, restrictions, warnings or instructions. They are also called road signs and road traffic signs. Traffic signs generally focus on safety. Setting eye-catching, clear and bright traffic signs is an important measure to implement traffic management and ensure safe and smooth road traffic. There are many types of traffic signs, which can be divided into: main signs and auxiliary signs; movable signs and fixed signs; illuminated signs, luminous signs and reflective signs; and variable information signs that reflect changes in the driving environment.

[0003] With the urbanization process and the development of urban road traffic in my country, cities around the country have attached more and more importance to the construction of road traffic signs and markings, and have increasingly realized that the construction of road traffic signs and markings is necessary for urban road traffic safety. However, in the construction and management of urban traffic signs and markings in various places, there are still insufficient and improper information. In addition to meeting the traffic management requirements within the current area, road or project scope, the setting of signs should also take into account the traffic management requirements of related roads and road networks. The information released should be continuous and systematic, and at the same time, it should also meet the prominence, readability and recognition when setting traffic signs.

[0004] Before setting up road traffic signs, the traffic control department needs to conduct a sand table demonstration to simulate the installation location of road traffic signs and the improvement of traffic after the installation of road traffic signs. In the sand table demonstration, the existing road traffic demonstration teaching aids model is inconvenient to place and easy to fall over when placed, so it is necessary to design and improve a road traffic demonstration teaching aids model.
