The Study on train separation control & safety braking model technology using balise for conventional lines

KORAIL carries out an improvement project of railway signaling system for the conventional line from the existing method which permits a train to move within limited speed the ground signal of ATS (automatic train stop) system. The proposed system makes possible that a train can be driven using a speed profile created by onboard signaling system (ATP) with the movement authority from ground balise. A driving test over 100,000 km is being executed by developing a tilting train for the speed elevation on the conventional line. And, the introduction of the tilting train by ATP system to the Jung-ang line is expected. However, a speed elevation on a curved line section has a restriction. Therefore, research on safety braking model and train separation control technology for the localization of ATP system is required preferentially. In this paper, we presented a safety braking model of ATP system and a train separation control method that use ground balise as variable information provider, and executed a performance simulation.
