With the vigorous development of China's expressways, intelligent traffic management plays an increasingly important role in ensuring safety and improving traffic management efficiency. The traffic information release system, also known as the traffic guidance information system, is an important part of the highway monitoring system and an important display means for the intelligent transportation system ITS (IntelligentTra ortatio). As one of the forms of intelligent traffic management, the information release carrier LED variable information board can display various images and texts, announce various traffic conditions and weather information, and issue traffic instructions to ensure traffic safety. The displayed images and texts can be pre-programmed, stored in a variable information board controller, or compiled and re-released on a computer that controls the variable information board.

In the information age and the rapid development of intelligent transportation systems, in the transportation field serving the public, the release of information has become an important service content. Various information display devices have become airports, railway stations, terminals, bus stations, highways, Highway service areas, urban roads, parking lots and other leading means of releasing information to the public. Among them, LED display screens are favored for their high brightness, high reliability, long life and low power consumption.

LED electronic display is an ideal public information display medium for displaying text, image, 2D or 3D animation and video signals such as TV, video and VCD. This display technology is widely used in many fields of social economy. The display of information is one of the important application areas. Led display is a new type of flat panel display device that appeared in the 1990s. It is a high-tech product integrating optoelectronic technology, microelectronics technology, computer technology and video technology. Its light-emitting part is composed of LEDs (ie, light-emitting diodes). The advantages are low power consumption, high brightness, clear picture, bright colors, long life and stable performance.

The display surface of the variable information board is generally composed of an LED display array. Each of the display units is also referred to as a pixel, and each pixel is pressed by LEDs of different illumination basic colors (red, green, blue, yellow). A certain proportion of the combination. The variable information board itself has functions such as display drive, detection and control, and is equipped with a remote communication interface to communicate with the center.

At present, there are two types of display panels commonly used on highways: one is a dual primary color display, which is a red and green dual primary color, 256 gray scales can display 65536 colors; the other is a full color display. For red, green and blue primary colors, the 256-level grayscale full-color display can display more than 16 million colors.

In order to reduce the frequency of highway traffic congestion and traffic accidents, improve highway operating conditions and existing safety guarantee systems, and reduce delays and losses caused by traffic accidents, traffic congestion, secondary accidents, and congestion, high-speed should be fully utilized. The role of the highway information release system protects the safe, high-speed and smooth operation of highways.

Various forms of led display screens have become the main release carriers for traffic guidance information. Common traffic-induced LED display modes include LED display variable information boards, path signs, variable identification signs, and the like. Traffic guidance information outdoor LED display, according to the requirements of road traffic management and the actual situation of traffic guidance information release display, has the following characteristics in specific use functions: high brightness, reasonable viewing angle; display color is mainly red, green and yellow; Display brightness is automatically adjustable; all-weather work, complex environmental conditions; remote control, intelligent detection; security, real-time, accuracy, high reliability.

Gantry type variable electronic display

The gantry-type variable electronic information screen is the main information transmission mode of the expressway. Because of its large size, the cross-way gantry is used as the support for the variable electronic display. The main monitoring computer implements remote control through the communication network to transmit and display. Various graphic information, timely release of different road conditions and various types of traffic information on different road sections to the driver, and publicity of traffic regulations and traffic knowledge to reduce reproducible congestion of expressways and reduce non-recurring accidents of expressways Influence, improve the safety of driving; thereby effectively diverting traffic and improving the efficiency of highway use.

Variable speed limit display (board)

The variable speed limit display screens are mostly installed in some key road sections with complicated road conditions or extra large bridges, and most of them are mainly circular or single-arm suspension single-block screens. The remote control of the monitoring center computer through the communication network, transmission and display of the speed limit mileage or brief traffic information of the road section, to prompt the vehicle to drive at a speed limit, to ensure the safety of driving.

Mobile traffic information screen

When the highway construction and maintenance, the highway competent department or construction personnel temporarily close or change lanes, it is very important to inform the road users of the traffic information. Fixed variable information boards are limited by the uncertainty of the road construction site or the distance is far away, which is not easy to function. The mobile traffic information screen (vehicle screen) is small, flexible and light, suitable for installation on a towed motor vehicle, and can be directly displayed at the target site anytime and anywhere, making up for the shortcomings of the fixed variable information board.

Guide finger (alarm) screen

In order to ensure the safety of highway construction workers and vehicles and other vehicles that are normally driving, highway vehicles must be equipped with eye-catching high-brightness signs to warn and guide subsequent vehicles to avoid accidents. The guiding warning screen is the necessary equipment for the construction work vehicles on the expressway.

Service display

The service led display refers to the LED equipment provided by the toll station area and the service area to provide various services and publicity. Through the charging plaza, the service area parking lot, and various indoor LED display screens, we can provide real-time road conditions and service assistance to the past passengers in time to facilitate the travel of the passengers and passengers, and improve the management level and external image of the road sections. .

Conclusion

The highway LED information release system not only enhances the running speed and driving safety of the expressway, but also improves the operational efficiency. More importantly, it has achieved good social benefits. It is believed that with the continuous increase of highway mileage and the continuous improvement of computer technology and the continuous improvement of highway monitoring technology, the system will play an increasingly important role on the expressway.
