Rail transportation intelligent system refers to a system that applies advanced information technology and intelligent technology to the field of rail transportation to enhance operational efficiency, improve service quality and ensure safety. With the acceleration of urbanization and the growth of transportation demand, rail transportation intelligent system is increasingly becoming an important part of urban development. According to relevant data, the global rail transportation intelligent system market size is growing year by year, and by 2026, the global rail transportation intelligent system market size will reach tens of billions of dollars. Asia-Pacific is the main growth area of the rail transportation intelligent system market, of which China, as the world's largest rail transportation market, the demand for intelligent systems continues to grow, and the market size of China's rail transportation system in 2021 will be about 31.8 billion yuan. Rail transportation intelligent system includes several key technologies and applications, such as train operation control system, station information management system, intelligent ticketing system, and passenger information service system. These systems improve the safety, convenience, and efficiency of rail transportation systems by integrating technologies such as sensors, communication networks, artificial intelligence, and big data analysis to realize functions such as train operation monitoring, intelligent dispatching, and passenger information management.
