[National Railway Administration: Carry out research on the application of artificial intelligence technology in trains, infrastructure, operation and maintenance systems] On October 12, the National Railway Administration issued the "15th Five-Year Plan for Railway Science and Technology Innovation". It mentioned that basic research on the application of "artificial intelligence + railway" should be deepened. Based on technologies such as artificial intelligence, the Internet of Things, big data and cloud computing, and using massive data on railway operations and maintenance, a railway-specific artificial intelligence model capable of accurate prediction and intelligent decision-making is established. Carry out research on the application of artificial intelligence technology in trains, infrastructure and operation and maintenance systems, explore the digital upgrade application of artificial intelligence technology in trains, infrastructure and intelligent operation and maintenance, and achieve safe online assessment of train operations and personalized service customization. Strengthen research on full-scenario system safety assurance technology, continue to carry out research on constitutive safety, active safety and information security of railway equipment, and accelerate the construction of system solutions for full life cycle services. Build a digital platform for railway industry supervision and build an "artificial intelligence + railway" national-level safety evaluation and risk assessment system.
