Thales and CFL concluded a 5th framework contract to upgrade the existing Traffic Management System, Aramis, with the Aramis C-DAS (Connected Driver Advisory System) module in Luxembourg.
The C-DAS, known as GreenSpeed, is an advanced driver advisory system developed according to industry standards such as SFERA to favour interoperability while preparing the autonomous train operations (ATO).
“With regards to rail operation, the Aramis C-DAS module represents an additional milestone that will enable us to deepen our efforts in punctuality improvement and energy efficiency. This system may also act as a catalyst in the context of CFL’s ATO implementation,” Henri Werdel, CFL Director of Infrastructure Management said.
GreenSpeed provides unparalleled operational excellence by closely linking the existing traffic management within Aramis to the real time situation of the users of the network. Respecting schedules and timing points, the optimal speed profile is presented to the train drivers as simple to follow advice in an intuitive and customised interface.
The algorithm-based driving advice ensures improved punctuality and reduced energy consumption as well as maintenance cost. It is important for both passengers and train operators today to save energy and reduce CO2 emission, and Aramis C-DAS module is a great way to ensure that those expectations are met.
In addition to delivering driving advice, Aramis C-DAS module collects journey data such as speed, position and estimated time of arrival. These data are available in OCC and in Aramis C-DAS BackOffice to provide a framework for streamlining the entire traffic operation by analysing and identifying suboptimal conditions. This leads to further commercial improvements by optimising timetables, dwell times and timing points on an informed basis and brings valuable understanding of driver performance.
The C-DAS works together with Aramis to optimise the traffic flow, to provide the ideal speed curve, ensuring strict adherence to the timetable, thereby providing a smooth journey, which is energy efficient, as the C-DAS ensures punctuality with the least amount of traction energy used.
