D3.1 – UC and scenarios for ATO in different GoA demos for G1 regional lines

*UNDER ERJU APPROVAL

Regional lines, like main lines, benefit from the introduction of ATO systems. The introduction of the ATO system can effectively reduce operating costs and can contribute to reduce overall infrastructure costs. The solutions explored in the present document are the introduction of ATO Grade of Automation 2 (GoA2) up to Grade of Automation 4 (GoA4) for regional applications. There are many similarities with what is applied on main lines. Since the same trains can circulate both on main lines and on G1 regional lines, interoperability must be guaranteed. The use of the ATO over ETCS signalling system is a must that has guided the integration of the solutions in the regional context. This report covers use cases for G1 regional lines that allow automation of train operation on low-traffic lines with moderate speeds. The ATO functionality developed is using ERTMS/ETCS as a platform. The report specifies several use cases and technical requirements that ATO must meet to improve performance and overall economic sustainability of regional lines. Subsequently, various grades of automation applicable were analysed. Grade of Automation is studied from GoA2, where a train driver is responsible for starting automatic operation and can intervene and manually drive the train in certain circumstances, to GoA3 which is driverless but with at least one train attendant on board. The on-board staff can handle doors, external and internal communication, facility issues and evacuating passengers if necessary. In GoA4, in which the train operates completely without on-board staff, start, stop, and operation of doors are performed completely without driver and train attendant. However, as a fallback system, the train can be operated by a remote operator (in conformity with GoA3). The use cases identified are particularly useful for regional lines. The present document constitutes the main outcome of FP6 WP3 Task 3.1 (Regional Rail CCS & Operations for G1 Lines Requirements & Specifications), which forms the basis for the demonstration campaigns to be performed by FP6 WP8 Task 8.1 (Development of individual demonstrator ATO GoA2 on G1 regional lines) and Task 8.2 (Development of individual demonstrator ATO GoA3/4 including perception and remote driving on G1 regional lines) during the second half of the project.
