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.

Driving advice systems for main line operation exist and have proven to be operable in in-service testing in several countries. Energy savings are lower than theoretically predicted but still high. Many operators are currently considering a system-wide introduction. The main technical barrier is the compilation of digital track data. Other obstacles are scepticism about the effectiveness and payback of the system as well as uncertainties about the acceptance by drivers. In view of the fact that DAS are among the most effective technological measures to reduce the fleet-wide energy consumption in mid-term perspective, strong efforts should be made to overcome remaining barriers. In long-term perspective, the integration of traffic situation into DAS algorithms could yield further efficiency gains. |
