RTS2010 - Coasting Boards Vs Optimal Control

Freightmiser is a proven in-cab driver advice system thatprovides information to train drivers to help them drive efficientlyand stay on time. The system has demonstrated fuelsavings of up to 22% on a wide variety of railways, including: bulk grain trains, long-haul freight trains, high-speed intercity passenger trains, slow roll-on-roll-off trains .The information provided to the driver can be tailored toeach application, and can includeamp;amp;amp;amp;#178; depictions of the track showing gradients, curves, speedlimits and trackside features, estimated arrival times at key locations, the ideal driving speed and driving mode.The driving strategy minimises the mechanical work doneby the train engines to move the train between key locationsin the time available, and so will save fuel or energy on anytype of traction system, with or without regenerative braking.The optimal driving strategy uses four driving modes:power, speed-hold, coast and brake. The optimal sequenceof control modes and precise switching points are continuouslyupdated based on the observed location and speed
