Features and uses of the guide screen
At present, the construction of expressway monitoring centers in various cities in my country has been basically completed, and a real-time broadcast and release system for urban expressway traffic information has been opened. LED traffic guidance screens have become the main force in the work of discharging traffic congestion and ensuring smooth traffic in major cities and highways.
What are the characteristics of traffic-induced screens?
1. High brightness, reasonable perspective design for different roads
The release of road traffic information is mainly aimed at road drivers. The viewing angle of highways and 70 degrees of urban roads should be clearly visible when the sunlight hits the surface of the display screen, so it needs to have a high brightness. Under normal circumstances, the visual distance is required to be about 200m.
2. The display colors are mainly red, green and yellow
The release of traffic information is mainly aimed at vehicle drivers. The driving vehicle has a short stay time within the visible distance, so it is necessary to avoid the use of complex multi-grayscale graphics and animation content, and the display content is mostly text and simple graphic logos. Considering the common colors of traffic sign signals, a red, green and yellow display screen is used. The three colors can display prohibitions, instructions, suggestions and warning messages respectively.
3. The brightness of the display is automatically adjustable
The traffic-induced screen works 24 hours a day, and the ambient illumination changes very greatly. It is necessary to ensure that the display is clearly visible during the maximum ambient illumination during the day, and to avoid "glare" phenomena in rainy days and nights. The brightness of the screen needs to be automatically adjusted according to the ambient illumination.
