Introduction

Urban rail transit operation safety assessment is an important means to ensure the safety of urban rail transit operation. In order to ensure that the urban rail transit

It is very important to clarify the technical requirements of safety assessment for the orderly development of safety assessment activities before initial operation, before official operation and during operation.

Safety assessment specification for urban rail transit operation

Part 1. Subway and Light Rail

1 Scope

GB/T 42334.1-2023 sets out how a metro or light rail line is assessed for operational safety. A completed railway is not the same thing as a railway ready to carry passengers: the civil works, the signalling, the rolling stock, the power supply and the stations may each be finished and certified, while the operating organisation — the staff, the rules, the emergency arrangements, the maintenance regime — is not yet capable of running them together. Chinese cities have built metro systems at a pace with few precedents, and the assessment regime exists because the gap between construction complete and safe to operate is where the risk concentrates. This part specifies the safety assessment before trial operation, the safety assessment before formal operation, and the safety assessment during operation, for metro and light rail projects. Assessing in three stages is the substance of it: an assessment before opening cannot tell whether an organisation will still be competent three years later. Under ICS 93.080.01 and CCS P51, it is written for metro operating companies, for the municipal transport authorities that authorise opening, and for the third-party assessment bodies.

This document specifies the safety assessment before initial operation, safety assessment before formal operation and safety assessment during operation of subway and light rail engineering projects.

the basic requirements of the assessment.

This document is applicable to the safety assessment before the initial operation of the subway and light rail project, the safety assessment before the formal operation and the safety during the operation.

3 Terms and Definitions

The following terms and definitions apply to this document.

3.1

initial operation

Passenger carrying on newly-built lines of urban rail transit after the trial operation is completed, the engineering project is accepted and the operation safety assessment is passed.

operational activities.

3.2

Official operationofficialoperation

The newly-built urban rail transit line has been in operation for at least one year, and all the remaining problems of the project have been rectified and rectified according to the regulations, and the projects have been completed.

Passenger-carrying operations that have passed the inspection and acceptance or have completed the design change procedures and passed the operational safety assessment.

3.3

rejectionproject

Some unit projects or project parts that have not been completed in accordance with the preliminary design of urban rail transit projects.

3.4

On the basis of the debugging of a single professional system of urban rail transit engineering, two or more professional systems are jointly debugged.

3.5

trial running

The urban rail transit project is completed, the cold sliding and hot sliding tests are successful, the system joint debugging is completed, and the basic conditions for driving are met.

Passenger-carrying operation is an activity of testing the availability, safety and reliability of the operating organization management and facility equipment systems.

4 Safety assessment before initial operation

4.1 Prerequisites

4.1.1 System joint debugging should be completed before trial operation. The trial run time shall not be less than 3 months, among which the train operation diagram shall be continuously organized
