It is generally believed that an intelligent transportation system refers to an integrated transportation system established on road traffic infrastructure, urban public transportation, and road transportation systems, which integrates information collection and processing, fusion and exchange, analysis and control, and ultimately aims to release information. It can achieve intelligent management. Improving traffic management, transportation efficiency, and traffic safety service level should be the application goal of intelligent transportation system construction, and the process of achieving this goal will to some extent promote the transformation of traditional transportation industry into modern transportation service industry.
In the related applications of LED display technology, public oriented road traffic information release display is one of the important application areas. In the public oriented dissemination of traffic guidance information, common display and dissemination methods in daily life include road traffic guidance screens, urban traffic guidance display screens, parking guidance screens, and road variable information signs. These different ways of releasing traffic guidance information are displayed in real-time based on relevant traffic road management requirements and the actual situation of road traffic information.
The characteristics of intelligent transportation systems
Intelligent transportation systems are actually a type of road traffic information communication system. Their emergence and development are based on different new technologies such as system integration, electronics, communication, and information services. Currently, they have permeated and applied to new transportation systems in the fields of aviation, water transportation, railway transportation, urban traffic guidance, highways, and subway rail transit. The construction of intelligent transportation systems can not only improve the capacity of road networks and the level of road traffic information services, but also have broad application prospects in the field of environmental protection, promoting the reduction of exhaust emissions and improving energy utilization efficiency.
In the process of building intelligent transportation systems, the construction and application of intelligent transportation information service systems are the main content of the development of the intelligent transportation field. Designing and establishing advanced transportation information service systems for the public is the duty and development trend of intelligent transportation systems. The intelligent transportation information services provided by intelligent transportation systems will focus on different types of transportation modes or fields.
The intelligent traffic information service system has many different traffic application fields, including variable information boards, variable speed limit signs, road traffic information service systems, etc. in highway applications, as well as traffic guidance systems, traffic management information comprehensive service systems, and road traffic information external release systems in urban traffic applications.
In the practical application field of intelligent transportation, the release of real-time traffic information for cities or roads is the main manifestation of intelligent traffic information services, which is to display traffic information in real time through various information display devices, most of which are relatively universal and common display devices. These display devices can include LED displays,
LCD displays, DLP displays, etc. With the continuous development of embedded technology, intelligent transportation information display systems have developed into integrated systems with functional scalability, multimedia technology, and networked connectivity.
