Introduction A comparison between the different unmanned transportation forms could be measured by the degree of freedom : 1. At sea and land two dimensions must be managed 2. In the air three dimensions must be managed 3. On rail one dimension must be managed Page 3
Grade of Automation (GoA) Definition GoA 0 GoA 1 GoA 2 GoA 3 is on-sight train operation, similar to a tram running in street traffic. is manual train operation where a train driver controls starting and stopping, operation of doors and handling of emergencies or sudden diversions. is semi-automatic train operation (STO) where stopping is automated but a driver in the cab starts the train, operates the doors, drives the train if needed and handles emergencies. is driverless train operation (DTO) where starting and stopping are automated but a train attendant operates the doors and drives the train in case of emergencies. GoA 4 is unattended train operation (UTO) where starting and stopping, operation of doors and handling of emergencies are fully automated without any on-train staff. Page 4
Concept GoA2 systems requires: Radio communication Onboard control systems Balises (Axle counters) Back-end systems GoA4 systems often requires: Platform screen doors Page 5
Concept Interaction of the Components Automatic Train Supervision WLAN Wayside Control Unit CBTC Interlocking Track wacancy Detection OPG Radar Access Point Eurobalise Point Machine Axle Counter Page 6
Concept Planning The planning tool enables: q q q Simulation both expansions and irregularities Emergency plans/scenarios can be established Conflict detection and resolution is actively running in the backend system Page 7

Safety Aspects Moving Block Movement authority Rear safety distance Safe braking distance Continuous communication Page 9
What are the benefits? Higher headway Possible to utilize the rail network to a higher degree Higher speed Shorter travel times leads to higher capacity Higher availability Precondition for higher degree of automation Economy Efficient Driving Page 10
What are the Challenges? The biggest challenges are: Vehicles Testing Approvals In many projects the existing trains are shall be adapted to automatic operation i.e. interaction with the speed control, breaks, service, diagnostic systems, door control systems etc. Brown field projects requires testing in parallel to the daily operation, whereas Green field projects can test until the system is ready. The suppliers use the CENELEC standards for their qualification of the systems. The safety authorities in Europe has started the uses CSM (common safety method) which is a risk driven approach.

How far are we in the Rail Industry The first unmanned metro London Underground's Victoria line, opened in 1967. GoA 2 GoA 3 More than 120 installation in the Americas, Asia and Europe (incl. Copenhagen S-bane). 4 installations (Barcelona, London, Budapest and Beijing). GoA 4 78 installations in the in the Americas, Asia and Europe. The rail industry has managed to develop an efficient and safe unmanned transportation over the last 50 years. Page 12
We cannot predict the future but we can invent it Page 13
