DD IEC-PAS 62267:2005 pdf download Railway applications — Automated Urban Guided Transport (AUGT) safety requirements
In the case of upgrading an existing transit system to a DTO or UTO system, the risksassociated with the existing system are outside the scope of this PAS. However, the riskassessment process described herein may be relevant, and its application is at the discretion ofthe safety authority having jurisdiction.
In the case of extending or modifying an existing DTO or UTO system in operation, this PASapplies only if the change is significant as determined by the safety authority havingjurisdiction; but the risks due to the relationship with the unchanged parts of existing systemsroling stock, traction power supply, signalling. platforms) shall be taken into account.

3 Terms, definitions and abbreviations
For the purposes of this document, the following terms, definitions and abbreviations apply
3,1Transportation systems
3.1.1 Automated Urban Guided Transport (AUGT)
metropolitan scale urban system featuring DTO or UTO, as defined below, with self-propelledvehicles mechanically guided on a guideway, which is separated from general road andpedestrian traffic, operating in an urban environment, and open to the general public withoutrestrictions:
8systems accepting exclusively automated trains are called “closed systems”
61
systems accepting a mixed traffic of automated trains and conventional trains (i.e..manually operated or semi-automated) are called “open systems”
3,1.2Automated People Movers (APM)
See ASCE (American Society of Civil Engineers) standard 21: Automated People Movers -Part 1
3.2Grades of automations
3.2.1
On-sight Train Operation (TOS)operation in which the driver (i.e. the train operator) has full responsibility and no technicalsystem is required to supervise his activities
3,2,2Non-automated Train Operation (NTO)
operation in which the driver (i.e, the train operator) is in the front cabin of the train observingthe guideway and stopping the train in case of a hazardous situation. Acceleration and brakingare controlled by the driver in conformance with wayside signals or cab-signalling. The signalling system and any associated wayside system supervise the activities of the driver.however, with respect to the signals and the speed, this supervision may be discrete, semi.continuous or continuous. Safe departure of the train from the station, including door closing, isthe responsibility of the operations staff whether onboard the train or on the station platform
3.2.3Semi-automated Train Operation (STO)
operation in which the driver is in the front cabin of the train observing the quideway andstopping the train in case of a hazardous situation. Acceleration and braking is automated andthe speed is supervised continuously by the system, Safe departure of the train from the stationis the responsibility of the operations staff, whether on board the train or on the station platform
3.2.4Driverless Train Operation (DTO)
operation in which additional control and detection systems are needed compared with STObecause there is no driver in the front cabin of the train to observe the quideway and stop thetrain in case of a hazardous situation.
An operations staff person is necessary onboard. Safe departure of the train from the station.including door closing (open point), can be the responsibility of the operations staff or may bedone automatically
3.2.5Unattended Train Operation (UTO)
operation in which additional control and detection systems are needed compared to DTObecause there is no on-board operations staff person necessary.
Safe departure of the train from the station, including door closing, is done automatically
3.2.6Automated transit system
DTO or UTO mode
3.2.7Conventional transit system
TOS,NTO or STO mode
3.3Vehicles
3.3.1independent train
train which is constructed (designed) for independent train operation
