With the development trend of LED display screen, LED display screen has quickly taken the lead in the field of transportation. The display of traffic information is one of the important application fields, especially with the arrival of the information age and the development of intelligent transportation systems, the release of information has become an important service content in the field of transportation serving the public, and various information display devices have become airports, railway stations, docks, bus stations, expressways Urban roads, parking lots and other leading means to release information to the public.
LED display is one of the display means of the intelligent transportation system
An intelligent Transportation System (ITS) refers to a smart information system that provides comprehensive transportation information services to the public or special audience groups. The intelligent traffic information service system generally includes information sources, information processing, information release display, etc. The release display mainly uses various multimedia display devices, such as LED displays, LCD displays, CRT displays, PDP displays, etc.
In China’s transportation industry, the airport flight dynamic information display system is relatively advanced in system composition, display terminals, and other aspects; The railway passenger guidance information display system started early. Traditionally, LED and CRT are the main display means. In recent years, it has developed rapidly. The system is connected with the passenger transport automation system, showing an excellent level of intelligence; The road traffic guidance system is rising rapidly and is in the process of development and improvement. Due to the environmental characteristics of road traffic, LED display has become the main means of information display.
LED display screen is the primary release carrier of road traffic guidance system
The road traffic guidance system is an important traffic information service system in the modern urban intelligent traffic management system. The system processes and analyzes the dynamic traffic conditions in real-time. The command and decision-makers in the control center release and display the traffic information, road conditions, etc. to reduce congestion and improve the road capacity through manual or automatic methods.
In practice, public-oriented traffic guidance information is generally released in the outdoor environment. Due to the high brightness of LED displays, various forms of LED display become the main release carrier of traffic guidance information. Common LED display modes of traffic guidance include traffic guidance LED display (variable message board), traffic guidance route display board, parking indicator board, variable sign, etc.
Outdoor LED display of traffic guidance information has the following characteristics in terms of specific use functions according to the requirements of road traffic management and the actual situation of traffic guidance information release and display: high brightness, reasonable perspective; The display colors are mainly red, green and yellow; The display brightness is automatically adjustable; Working all day, with complex environmental conditions; Remote control, intelligent detection; High requirements for security, real-time, accuracy and reliability. LED display has broad prospects in the field of transportation.
