The classification of LED traffic guidance screens: LED traffic guidance screens are mainly divided into five categories: gantry-type variable message signs, variable speed limit signs (boards), mobile traffic information screens, directional guidance (warning) screens, and service screens. Gantry-type variable message signs: Application scenarios: The main information dissemination method on expressways. Features: Large in size, using a cross-road gantry as the support, and remotely controlled by the main monitoring computer through a communication network. Functions: Display various graphic and text information, promptly inform drivers of road conditions and various traffic information on different sections, and promote traffic laws and knowledge to reduce expressway congestion and improve driving safety. Variable speed limit signs (boards): Application scenarios: Key sections with complex road conditions or large bridges. Features: Mostly circular or single-arm suspended single screens, remotely controlled by the monitoring center computer through a communication network. Functions: Display the speed limit mileage of the section or brief traffic information, prompt vehicles to drive at the speed limit, and ensure driving safety. Mobile traffic information screens: Application scenarios: Used for temporarily closing or changing lanes during expressway construction and maintenance. Features: Compact, flexible, and lightweight, suitable for installation on trailer vehicles, and can be placed directly at the target site at any time. Functions: Make up for the deficiency of fixed variable message boards that are difficult to be effective when the construction site is uncertain or far away. Directional guidance (warning) screens: Application scenarios: On expressway construction vehicles. Features: High-brightness signs used to warn and guide subsequent vehicles. Functions: Ensure the safety of expressway construction personnel and vehicles as well as other normally traveling vehicles, and prevent accidents. Service screens: Application scenarios: Toll stations and service areas. Features: LED devices providing various services and publicity. Functions: Provide real-time road conditions and service assistance information to passing drivers and passengers through indoor LED screens, facilitating their travel and enhancing the management level and external image of the section. The following are sample pictures of LED traffic guidance screens: These classifications are based on the different application scenarios and functional requirements of LED traffic guidance screens. Each type of display screen has its unique characteristics and functions, and together they constitute an important part of the intelligent transportation system.
