Description / Beschreibung /
The Driver Advisory System (DAS) is an on-train driver support system which advises a driver on the most energy-efficient speed profile with which to meet the train’s current schedule. The DAS receives as input the current schedule (which may be updated at any time) together with a range of static or near-static data relating to the track, namely: topology, topography, asset locations and speed restrictions; and various parameters relating to the vehicle itself.
