Main technical content: As a new-generation train operation control system, the Train Autonomous Control System (hereinafter referred to as "TACS") features safety, high efficiency, flexibility, economy, and ease of deployment. The system offers improved functionality and performance with a more streamlined architecture, which differs significantly from traditional CBTC systems. At present, no relevant standards have been issued in China. To standardize the system design requirements of urban rail transit TACS, regulate the system architecture, subsystem functions, and function distribution, and provide standardized guidance for the design and development of TACS-related products, as well as for the design, construction, and acceptance of lines adopting TACS, this specification has been formulated. This specification includes: scope; normative reference documents; terms and definitions; abbreviations; system design; ATP function distribution; ATO function distribution; ATS function distribution; and clause explanations. During the preparation of this specification, extensive investigations and studies were conducted. It is based on current relevant national and industry standards and norms, and actively incorporates the opinions and suggestions of relevant units in urban rail transit engineering construction, design, operation, management, and scientific research. It closely combines the system characteristics of TACS and the characteristics of urban rail transit projects in Shanghai, and is both innovative and forward-looking.
