LED display is widely used in many fields of social economy. Among the many application fields of LED display, the display of traffic information is one of the important application fields, especially the arrival of the information age, the development of intelligent transportation systems, and the release of information in the field of transportation serving the public. Service content, various types of information display equipment have become the leading means for the public to release information to the public at airports, railway stations, docks, bus stations, highways, urban roads, parking lots, etc. Among them, LED display is based on its high brightness and high reliability Features are favored.

       LED is one of the means of intelligent transportation system display

       Intelligent Transportation System (IntelligentTrans-portationSystem, ITS for short) refers to an intelligent information system that provides comprehensive transportation information services to the public or a special audience. The intelligent traffic information service system generally includes information sources, information processing, and information release display. The release display mainly uses various multimedia display devices, such as LED display, LCD display, CRT display, PDP display Wait.

       The development of modern information display technology has formed a series of information display products such as CRT, LCD, PDP, LED, EL, DLP and so on. Looking at the development of various types of display products, LCDs under 14 inches dominate, 14-32 inches are dominated by CRTs, 40-70 inches or even 100 inches will be the market for PDPs, and above 100 inches, whether indoor Outdoor, LED display has become the mainstream product with absolute advantages.

       In China's transportation industry, relatively speaking, the airport flight dynamic information display system is generally ahead in terms of system composition and display terminals; the railway passenger guidance information display system started earlier, and the display means traditionally use LED and CRT as the Mainly, it has developed rapidly in recent years. The system is networked with the passenger transportation automation system, showing an excellent level of intelligence; the road traffic guidance system is rapidly emerging and is in the process of development and improvement. Due to the environmental characteristics of road traffic, LED display has become the main information Display means.

       LED display is the main 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 traffic dynamics in real time. The command and decision makers of the control center publish and display traffic information externally, manually or automatically. Road conditions, etc., reduce the degree of congestion and improve road capacity.

       In practice, public-oriented traffic guidance information is generally released in an outdoor environment. Due to the high brightness characteristics of LED displays, various forms of LED displays have become the main release carrier of traffic guidance information. Common traffic guidance LED display methods include traffic guidance LED display screen (variable information board), traffic guidance route display sign, parking sign, variable signage, etc.

       The outdoor LED display of traffic guidance information, according to the requirements of road traffic management and the actual situation of traffic guidance information release and display, has the following characteristics in specific use functions: high brightness, reasonable viewing angle; display colors are mainly red, green, and yellow; The display brightness is automatically adjustable; all-weather work, complex environmental conditions; remote control, intelligent detection; high safety, real-time, accuracy, and reliability requirements.

       LED display has a bright future in transportation

       With the continuous improvement of material technology, the application range of LEDs has been widened. Looking forward to the application of LED display in the transportation field, there are the following aspects

Worthy of attention:

        Strong traffic signal market demand

        Ultra-bright, high-power LED devices have been widely used in urban traffic lights. LED signal lights are favored by urban traffic management departments for their high brightness, high reliability, low use cost, and long life. From a nationwide perspective, the urbanization process and the development of road municipal construction, the number of new traffic intersections is increasing, and the traditional traffic lights currently used are also being replaced by LED lights. It is predicted that the domestic road LED traffic signal market capacity should be in the tens of billions. In addition, there is also great market potential for highway lane lights, signals for airports, railways, shipping, etc., and signs. www.tranbbs.com

        Highway LED variable information boards have become standardized and standardized products

        Highway LED variable information boards, variable speed limit signs and other products have developed into standardized and standardized products in highway construction. Existing roads need to be supplemented and perfected. New roads have requirements for standard and standardized supporting facilities. It has been officially released for implementation. It is estimated that the annual market capacity of display products such as variable information boards and variable speed limit signs on highways will be around 300 million to 500 million yuan.

       The automotive industry has broad application prospects

       According to research statistics, the response time of the LED as the main brake light of the car is 80ns faster than the traditional incandescent lamp, and driving on the highway will increase the safety distance of 4 to 6 meters. Due to the characteristics of LEDs such as good seismic performance, power saving, and green environmental protection, the application of automotive lighting and lighting will also develop well. At present, many domestic and foreign automobile manufacturers have begun to use LED brake lights, instrument lights and lighting.

        Urban road traffic guidance, signs, etc. are gradually expanding

        Road traffic guidance LED displays are growing rapidly in various cities, and product technology is developing rapidly. In terms of product types, traffic-inducing LED display screens are still mainstream products, but various simple, economical, and practical variable traffic information signage products will be popularized and form a dominant.

        Beijing 2008 Olympic Games and Shanghai 2010 World Expo bring development opportunities

        The holding of the 2008 Beijing Olympic Games and the 2010 Shanghai World Expo brought huge business opportunities for LED displays. In the field of urban transportation, the LED display market will increase significantly.
