   Driving advice systems in main line operation  evaluated  
Driving advice systems are on-board tools giving recommendations to drivers for a more energy efficient driving style. In main line operation, rather sophisticated algorithms taking into account a number of track and vehicle characteristics exist to continuously calculate the optimum driving pattern for the remaining route.
