Patent ID: 8374739

Claim:
A method comprising: receiving by a signal receiving unit location identification blocks for a first train and a second train, the first train located in front of the second train; determining by a track circuit the number of blocks that are open between the first and second train; determining by a target speed calculating unit a brake pattern for the second train based on the location identifications and the number of open blocks; determining by the target speed calculating unit an average speed of the first train; predicting by the target speed calculating unit a time when the first train will pass the next block based on the location and average speed of the first train; determining by the target speed calculating unit a target speed for the second train based on the predicted time the first train will pass the next block and the brake pattern; and wherein the determined average speed of the leading train based on the time taken for the leading train to come out from the block existing just behind the block occupied by the leading train and distance information of the block existing just behind the block occupied by the leading train, and predicted time when the first train will pass the next block is based on the travel speed of the leading train and distance information of the block occupied by the leading train.
