What are the classifications of LED traffic guidance displays? In the information age and the rapid development of intelligent transportation systems today, in the field of transportation that serves the public, the release of information has become an important service content, and various information display devices have become the leading means of releasing information to the public in highway sections. Common traffic guidance LED display methods include LED display variable information boards, route signs, variable identification signs and so on.
Traffic guidance information outdoor LED display, 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; it works around the clock, with complex environmental conditions; remote control, intelligent detection; high security, real-time, accuracy, and reliability.
1. Door frame variable display
Gantry-type variable intelligence screen is the main information dissemination method of expressways. Because of its large size, cross-road gantry is generally used as the support of the variable electronic display screen. The main monitoring computer implements remote control through the communication network, transmits and displays the information. A kind of graphic information, timely release of different road sections and various types of traffic information to drivers, and publicity of traffic laws and traffic knowledge, so as to reduce expressway reproducible congestion and reduce the impact of expressway non-reproducible accidents , The purpose of improving driving safety; thereby effectively diverting traffic and improving the efficiency of expressway use.
2. Variable speed limit display (board)
Variable speed limit LED display screens are mostly set on some key sections of roads with complicated road conditions or super large bridges, mostly circular or single-arm suspension monolithic screens. The monitoring center computer implements remote control through the communication network, and transmits and displays the speed limit mileage or brief traffic information of the road section, which plays a role in prompting the vehicle to drive in accordance with the speed limit and ensure driving safety.
3. Mobile traffic information screen
During expressway construction and maintenance, the expressway authority or construction personnel temporarily close or change lanes, and how to inform road users of traffic information is very important. The fixed variable information board is limited by the uncertainty of the road construction site or the long distance, which is not easy to function. The mobile LED traffic information screen (vehicle screen) is compact, flexible and light, suitable for installation on a trailer-mounted motor vehicle, and can be placed on the target site anytime and anywhere for direct display, which makes up for the lack of fixed variable information boards.
4. Guiding finger (warning) screen
In order to ensure the safety of highway construction workers and vehicles and other vehicles in normal driving, highway operating vehicles must be equipped with eye-catching high-brightness signs to warn and guide other vehicles in the future to avoid accidents. The directional warning screen is a necessary equipment for construction vehicles on expressways.
5. Service display
Service LED display refers to the LED equipment installed in the toll station area and service area to provide various services and publicity. Various LED displays installed in toll plazas, service area parking lots, and indoor installations provide timely information such as real-time road conditions and service assistance to past drivers and passengers, so as to facilitate the travel of the drivers and passengers, and improve the management level and external image of the road section
