Full title and description
IEC 62267:2009 — Railway applications — Automated urban guided transport (AUGT) — Safety requirements. This international standard defines high-level safety requirements for automated urban guided transport systems using driverless or unattended self-propelled trains running on exclusive guideways, addressing the safety measures required to compensate for the absence of on-board drivers or attendants depending on the automation level of the system.
Abstract
IEC 62267:2009 provides a framework of safety goals, identified hazardous situations, required safeguards and verification criteria for Automated Urban Guided Transport (AUGT) systems (also known as driverless urban transit). It focuses on system-level, high-level requirements rather than detailed implementation rules, and is intended to support design, assessment, verification and operation of AUGT systems.

Scope
IEC 62267:2009 covers high-level safety requirements applicable to automated urban guided transport systems with independent self-propelled trains operating on an exclusive guideway. The standard addresses safety functions and safeguards required to mitigate hazards that arise when there is no driver or on-board attendant performing operational tasks, and includes requirements for identification of hazardous situations, assignment of safety requirements, and verification of system-level safety. It does not replace detailed signalling, control or rolling-stock specifications but complements them by defining system-level safety objectives.
Key topics and requirements
- Definition of entities to be protected (passengers, staff, public, infrastructure) and identification of hazardous situations specific to AUGT systems.
- High-level safety requirements and safety objectives to compensate for absence of onboard staff (DTO/UTO scenarios and variants).
- Methodology for hazard analysis, allocation of safety functions and required safeguards at system level.
- Verification and validation principles for demonstrating that safety requirements are met.
- Guidance on information for use, and specific considerations for upgrading existing lines to unattended operation.
Typical use and users
Used by system integrators, transit authorities, signalling and control engineers, safety assessors, regulators and certification bodies involved in planning, designing, upgrading or certifying automated urban transit systems. It is referenced during system safety assessments, requirements engineering, verification planning, and when preparing documentation for regulatory approval of driverless operations.
Related standards
IEC 62267:2009 references and complements other railway and automation standards such as IEC 62278 (RAMS requirements), IEC 62290‑1 (urban guided transport command/control principles), and IEC 62425 (safety-related electronic systems for signalling). It also supersedes IEC PAS 62267:2005 (the earlier Publicly Available Specification).

FAQ
Q: What is this standard?
A: IEC 62267:2009 is an international standard that specifies high-level safety requirements for Automated Urban Guided Transport (AUGT) systems — driverless or unattended urban rail vehicles operating on exclusive guideways.
Q: What does it cover?
A: It covers system-level safety objectives, identification of hazardous situations, assignment of safeguards, and verification principles needed to compensate for the absence of onboard drivers or attendants. It addresses upgrades to unattended operation and provides guidance for safety assessment rather than detailed subsystem design rules.
Q: Who typically uses it?
A: Transit authorities, system integrators, signalling and control engineers, safety assessors, certifying bodies and regulators involved with design, deployment, verification or certification of automated urban transit systems.
Q: Is it current or superseded?
A: IEC 62267:2009 is the published edition that replaced the earlier IEC PAS 62267:2005. Users should check national adoptions or later amendments for any updates, but the 2009 edition is the authoritative IEC publication.
Q: Is it part of a series?
A: It forms part of the family of IEC standards addressing railway safety, RAMS and control systems (for example IEC 62278, IEC 62290‑1 and IEC 62425) and is intended to be used alongside these more detailed or related standards.
Q: What are the key keywords?
A: Automated urban guided transport, AUGT, unattended operation, driverless, safety requirements, hazard analysis, system verification, IEC 62267.
