Introduction
Urban rail transit operation safety assessment is an important means to ensure the safety of urban rail transit operation. GB/T 42334 is intended to establish the technical basis for safety assessment of different systems of urban rail transit and is composed of three parts.
Part 1: Subway and light rail. The purpose is to specify the basic technical requirements for the operational safety of metro and light rail urban rail transit systems, and to give test methods to support the development of operational safety assessment.
Part 2: Monorail. The purpose is to specify the basic technical requirements for the operation safety of single-track urban rail transit, to give test methods, to support the development of operational safety assessment.
Part 3: tram. The purpose is to specify the basic technical requirements of tram-type urban rail transit operation safety, to give test methods, to support the development of operational safety assessment.
1 Scope
This document specifies the basic requirements for the initial pre-operation safety assessment, formal pre-operation safety assessment and safety assessment during operation of metro and light rail projects. This document applies to the initial pre-operational safety assessment, formal pre-operational safety assessment and operational safety assessment of metro and light rail projects.

6.1.2 The requirements and methods of the line network control center function assessment are as follows.
On-site inspection of the line network control center operating status monitoring function, can be continuous monitoring and management of traffic, passenger flow, equipment operation and major faults, passenger video a) information, etc. 24h.
6.1.3 check the operation organization and coordination records, pre-determined surface passenger flow full rate or station capacity exceeds the warning value, the line operation control center should apply to the line network control center for neighboring stations to implement line network-level passenger flow control measures, including but not limited to the temporary closure of interchange channels or reduce the interchange channel through capacity, one-way open or temporary closure of the exit population.
Check the emergency dispatching command records, a single line in the line network interruption of traffic, extended interval, closed part of the car 6 stations and other large failure to reduce transport capacity and service levels, the line operation control center shall apply to the line network control center or line network control center directly to the neighboring lines to control the flow of passengers into the faulty line to reduce the safety risks of adjustment measures, including but not limited to the neighboring lines on The downstream trains do not arrive at the same time at the interchange, the downstream trains on the neighboring line do not stop at the interchange or reduce the number of trains on the neighboring line, etc.
On-site inspection of the line network control center emergency information release function, when the release conditions corresponding to the release level to require other lines or line network with the release of information, the line network control center is responsible for coordinating the release of emergency information for passengers or the line network control center will be authorized to release emergency information to the affected relevant line operation control center county body implementation.
Check the external liaison and contact records or joint emergency drill records, should be established and transportation, public security, meteorology, health, power supply, communications and other departments or units of liaison work mechanism, liaison work mechanism to operate effectively.
