What are the four major functions and five categories of LED traffic guidance screens? The four major functions of LED traffic guidance screens are:
High Brightness and Automatic Adjustment: LED traffic guidance screens should have high luminance and wide viewing angles, and be capable of automatically adjusting brightness according to ambient light intensity to ensure clear content display even under direct sunlight. They should also be able to operate continuously for 24 hours a day and have a normal visible distance of approximately 200 meters.
Diverse Information Display: Support for diverse colors, methods, and content, allowing real-time and accurate release of traffic information in the form of audio, video, images, and text based on the requirements of the traffic guidance system and the environment, facilitating pedestrians' access to information.
High Protection Grade Design: Outdoor LED traffic guidance screens must meet the IP65 protection grade requirements and take specific measures for complex outdoor environments (such as temperature, power supply, rain protection, moisture protection, corrosion resistance, and lightning protection) to ensure high reliability.
Remote Control and Intelligent Detection: Real-time, accurate, and reliable display of traffic information through remote control, and also equipped with intelligent detection functions to ensure system safety and stability.
Five Categories of LED Traffic Guidance Screens:
Portal-type variable message sign: It adopts a cross-road gantry as the support structure and is remotely controlled by a main monitoring computer to release graphic and text information, promote traffic regulations and knowledge, reduce highway congestion and accidents, and improve driving safety and efficiency.
Variable speed limit sign (board): It is set up in key sections with complex road conditions or large bridges, mainly in the form of circular or single-arm suspended single screens, remotely displaying speed limit mileage or brief traffic information to prompt vehicles to drive within the speed limit.
Mobile traffic information screen: Compact and flexible, it is suitable for installation on trailer-type motor vehicles and can be placed at the target site anytime and anywhere, making up for the shortcomings of fixed variable message boards. It is suitable for temporary traffic information release during highway construction and maintenance.
Directional guidance (warning) screen: It is an essential equipment for highway construction vehicles, warning and guiding subsequent vehicles through high-brightness signs to ensure the safety of construction personnel and vehicles and prevent accidents.
Service-oriented display screen: Installed in toll stations and service areas, it provides real-time road conditions and service assistance information, facilitating the travel of drivers and passengers and enhancing the management level and external image of the section.
