The Simulation of Train Separation Control Algorithm by Movement Authority Using Beacon

Korean National Railroad is planning using the on board signaling system for putting KTX and existing equipment to a good. If we use a on-board signal mode, we can improve headway more than the classical ground signal mode but there can be places where the improvement of headway is impossible in a certain section because of physical constraints. So a new algorithm for train separation control is necessary to beacon. Train separation control system by movement authority and beacon does not depend on conventional track circuit. Therefore, position and distance control of train to prevent collision with leading train may become important safety factor. This paper suggests an investigation of train separation control algorithm using movement authority of several units efficiently for this. This paper is come up with an algorithm for this situation.
