CCTV News: Recently, the General Office of the Ministry of Transport issued the "Operation Technology and Management Specifications for Fully Automatic Operation System of Urban Rail Transit (Trial)" (Jiebanyun [2024] No. 70, hereinafter referred to as the "Specifications").

Since the operation of the first fully automatic operation line independently developed in China in 2017, 21 cities in China have opened 50 fully automatic operation lines with an operating mileage of about 1,480 kilometers. The fully automatic operation system has played an important role in improving the system's operating reliability and improving the level of operational services. However, the stories of the fully automatic operation lines of urban rail transit in recent years also reflect that they still have shortcomings and deficiencies in multi-professional coordination and safety management. On the basis of clarifying technical conditions and building a solid safety bottom line, we need to further promote the coordinated adaptation of operation management and technical level, and better guide the technological development of fully automatic operation systems.

The "Specifications" stipulate the unique functions and technical changes of fully automatic operation systems based on the existing ATO (automatic operation of trains) systems, including driving, passenger transport, safety assessment and other management methods and operation technical specifications for signal, vehicle, etc., with a total of 7 parts, mainly including the following contents:

1. The overall requirements. Starting from improving safety and reliability, the overall requirements for drivers to be on duty in the driver's room, strengthen automatic adjustment of train operations, strengthen system status monitoring and safety redundancy, and improve technical and management coordination to ensure safety.

The second is the technical requirements of facilities and equipment. The basic functions and performance requirements of facilities and equipment are proposed for the five major systems of signal, vehicle, communication, platform door, comprehensive monitoring and passenger service systems in terms of system linkage, interface matching, parameter optimization, human-computer interaction, etc., to consolidate the inherent safety level of fully automatic operation systems.

The third is system integration requirements. Based on the safety management and quality control of the entire life cycle, the work content of system integration is clarified, as well as the integration requirements such as system interface matching, safety and quality card control during design liaison, comprehensive joint debugging, and trial operation.

The fourth is operational management requirements. Safety risk control requirements are put forward from the aspects of organizational structure, rules and regulations, personnel control, etc., and requirements such as key positions and personnel skills maintenance, as well as key operating processes and safety card control measures.

In addition, the appendix of the "Specifications" clearly states that it is necessary to support local governments to actively explore unmanned driving technologies such as obstacle detection and remote train control, provide support for the subsequent realization of unmanned trains, actively support technological innovation, and promote the orderly development of fully automatic operating systems. At the same time, requirements are put forward for existing fully automatic operation lines that do not meet the requirements of this specification and lines that are not fully automatic updated and transformed into fully automatic operation.
