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 superior functionality and performance with a more streamlined architecture, which differs significantly from traditional CBTC systems. At present, there are no relevant standards in China. To standardize the requirements for urban rail transit TACS systems, regulate the design, maintenance, and bidding processes of TACS systems, and provide guidance for standardizing the research, construction, acceptance, operation, and maintenance of TACS-equipped lines, this specification has been formulated. This specification includes: scope; normative reference documents; terms and definitions; abbreviations; basic requirements; functional requirements; performance requirements; and clause explanations. During the preparation of this specification, extensive research and investigation were conducted. It is based on current relevant national and industry standards and specifications, 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.
