Common 5 types of LED traffic guidance screen display methods
What are the classifications of LED traffic guidance displays? In today’s information age and the rapid development of intelligent transportation systems, in the transportation field serving the public, information release has become an important service content, and various information display devices have become the dominant means of releasing information to the public on expressways. Common traffic guidance LED display methods include LED display variable information boards, path signs, variable logo signs, etc.
The outdoor LED display of traffic guidance information, according to the requirements of road traffic management and the actual situation of the release and display of traffic guidance information, has the following characteristics in terms of specific use functions: high brightness, reasonable viewing angle; display colors are mainly red, green and yellow; Display brightness is automatically adjustable; all-weather work, complex environmental conditions; remote control, intelligent detection; high security, real-time, accuracy and reliability.
1. Gantry type variable display screen
The gantry-type variable information screen is the main information dissemination method on the expressway. Due to its large size, a cross-road gantry is generally used as the bracket for the variable electronic display screen. The main monitoring computer implements remote control through the communication network. Various types of graphic information, timely release of different road conditions and various traffic information on different road sections to drivers, and publicity of traffic laws and traffic knowledge, so as to reduce the recurring congestion of expressways and reduce the impact of non-recurring accidents on expressways , the purpose of improving driving safety; thus effectively diverting traffic and improving the efficiency of expressway use.
2. Variable speed limit display (board)
The variable speed limit LED display is mostly set on some key road sections with complex road conditions or extra-large bridges, and most of them are circular or single-arm suspended single-screen displays. The monitoring center computer implements remote control through the communication network, transmits and displays the speed limit mileage or brief traffic information of the road section, and plays the role of prompting the vehicle to drive according to the speed limit and ensuring driving safety.
3. Mobile traffic information screen
During highway construction and maintenance, it is very important how to inform road users of traffic information when highway authorities or construction personnel temporarily close or change lanes. The fixed variable information board is limited by the uncertainty of the road construction site or the long distance, so it is not easy to function. The mobile LED traffic information screen (vehicle screen) is small, flexible and light, suitable for installation on trailer vehicles, and can be placed on the target site for direct display anytime, anywhere, making up for the lack of fixed variable information boards.
4. Guide finger (warning) warning screen
In order to ensure the safety of expressway construction workers, vehicles and other vehicles running normally, expressway operation vehicles must be installed with eye-catching high-brightness signs to warn and guide other vehicles to avoid accidents. The guidance warning screen is the necessary equipment for construction vehicles on the highway.
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. Through toll plazas, service area parking lots, and various LED displays installed indoors, various information such as real-time road conditions and service assistance are provided to passing drivers and passengers in a timely manner, which facilitates the travel of drivers and passengers, and improves the management level and external image of the road section.
