Generally speaking, intelligent transportation system refers to the transportation system established on road traffic infrastructure, urban public transportation and road transportation system, which integrates information collection and processing, integration and exchange, analysis and control, and finally integrates the information release as the goal to realize intelligent management of transportation system.Improving traffic management, transport efficiency and traffic safety service level should be the application goal of the construction of intelligent transportation system, and the realization process of this goal will promote the transformation of traditional transportation industry to modern transportation service industry to some extent.

In the relevant applications of LED display technology, public road traffic information release display is an important application area.In the public information release mode of traffic guidance, common display information release mode in daily life include road traffic guidance screen, urban traffic guidance screen, parking guidance screen and road variable information sign.These different modes of traffic guidance information release are displayed in real time according to relevant traffic road management requirements and the actual situation of road traffic information.

Intelligent transportation system is actually a kind of road traffic information communication system, its generation and development is based on system integration, electronics, communications, information services and other new technology, has been penetration and applied to aviation, water transport, rail transport, urban traffic induction, highways, subways, new traffic system in the field of rail transit.The construction of intelligent transportation system can not only improve the capacity of road network and road traffic informatization service level, but also have a broad application prospect in the field of environmental protection, reducing exhaust emission and improving energy utilization efficiency.

During the construction of intelligent transportation system, the construction and application of intelligent transportation information service system is the main content of the development of intelligent transportation field. It is the due meaning and development trend of intelligent transportation system to design and establish an advanced transportation information service system for the public.For different types of transportation modes or different transportation fields, intelligent transportation information service provided by intelligent transportation system will focus on different aspects.

Intelligent traffic information service system has a number of different application areas, including not only the highway applications of variable information board, variable speed limit signs, traffic information service system, etc., as well as the urban traffic applications of traffic guidance system, traffic management information integrated service system, road traffic information release system, etc.

In the field of intelligent transportation applications, or city road of real-time traffic information release is the major form of intelligent traffic information service, which is through a variety of information display device displays real-time traffic information release, most is a general and common display device, the display device can include LED display, LCD, DLP display screen, etc.With the continuous development of embedded technology, intelligent traffic information display system has developed into an integrated system with expandable functions, multimedia technology and network connection.

Due to the continuous development and progress of LED display technology, LED display equipment products have been widely used in the field of intelligent traffic information display, which has become the mainstream way of modern traffic information display.In the field of intelligent traffic information display, corresponding traffic information display equipment products are required to release and display current actual road traffic information in real time according to the requirements of road traffic management and traffic induction information. Among them, LED display equipment products have the following characteristics in actual engineering application scenarios:

(1) LED display has high brightness and reasonable viewing Angle.The information release of road traffic induction is mainly aimed at participants of road traffic, and the general situation is driving vehicles, so the visual Angle of the display product is not required.Considering that in the case of direct sunlight display screen, the display content of the display product should maintain a certain clear visibility, so the display product is required to have a higher brightness.

(2) LED display products can work continuously and adapt to different environmental conditions.Due to the induced traffic information LED display workplaces are generally outdoor conditions, related to the external environment is complicated and changeful, consideration should be given to the work place the highest environmentally benign most low temperature, rainfall, humidity, air quality and environmental requirements of extreme weather, etc, to ensure the information of traffic to a great extent shows that the stability and reliability.

(3) LED display can be monitored remotely to realize intelligent detection.Due to the use requirements of the actual scene, the installation location of the LED display used to release traffic information is usually distributed within a larger area range. In this scenario, the traffic management control center is usually required to carry out the proper monitoring of the single LED display product on site.Using remote control method to carry out daily maintenance and environmental detection of LED display screen will be more convenient and save resources.
