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
