Among the related applications of LED display technology, public oriented road traffic information release and display is one of the important application fields. Among the public oriented release methods of traffic guidance information, the more common display and release methods in daily life include road traffic guidance screen, urban traffic guidance screen, parking guidance screen and road variable information signs. These different traffic guidance information release methods are displayed in real time according to the relevant traffic road management requirements and the actual situation of road traffic information.
Characteristics of intelligent transportation system
Intelligent transportation system is actually a road traffic information and communication system. Its emergence and development is based on other different new technologies such as system integration, electronics, communication and information services. در حال حاضر, it has penetrated and applied to new transportation systems in the fields of aviation, water transportation, railway transportation, urban traffic guidance, Expressway and subway rail transit. The construction of intelligent transportation system can not only improve the road network capacity and road traffic information service level, but also have broad application prospects in the field of environmental protection, reduce exhaust emissions and improve energy efficiency.
In the process of building intelligent transportation system, the construction and application of intelligent transportation information service system is the main content of the development of intelligent transportation field. طراحی و استقرار یک سیستم خدمات اطلاعات حمل و نقل پیشرفته برای عموم مردم معنا و روند توسعه سیستم حمل و نقل هوشمند است. برای انواع مختلف حالت های حمل و نقل یا زمینه های مختلف حمل و نقل, خدمات اطلاعات حمل و نقل هوشمند ارائه شده توسط سیستم حمل و نقل هوشمند تمرکز کرده و متفاوت خواهد بود.
سیستم خدمات اطلاعات ترافیکی هوشمند دارای زمینه های کاربردی مختلف ترافیک است, including not only variable information information board, variable speed limit sign, road traffic information service system in Expressway applications, but also traffic guidance system, traffic management information integrated service system, road traffic information external release system in urban traffic applications.
In the practical application field of intelligent transportation, the release of urban or road real-time traffic information is the main form of intelligent traffic information service, به این معنا که, انتشار و نمایش زمان واقعی اطلاعات ترافیک از طریق دستگاه های مختلف نمایش اطلاعات, اکثر آنها دستگاه های نمایش عمومی و رایج هستند. این دستگاه های صفحه نمایش می توانند شامل صفحه نمایش LED باشند, صفحه نمایش LCD, صفحه نمایش DLP, و غیره. با توسعه مداوم فناوری تعبیه شده, سیستم نمایش اطلاعات حمل و نقل هوشمند به یک سیستم یکپارچه با عملکرد مقیاس پذیر تبدیل شده است, فناوری چند رسانه ای و اتصال به شبکه.
