레벨전환[ERTMS( Level 1)→ STM(TVM)]규격 소개 및 국내 적용 현황

Domestic National signaling system has reviewed and prepared the type of ERTMS(European Railway Traffic Management System) signaling system. ERTMS system is the alternative signaling system to calculate the distance to go instead of the existing ATS system to supervise only limited speed. these system has implemented the domestic intercity railway and let the train be operating due to more safe than existed ATS system . Afterward these signaling system seems to be estimated to expand more and more as to ERTMS wayside and On board system. The main merit of ERTMS system is to define the specification in ERTMS standard not like the classical signaling system. This means that wayside can be implemented by ERTMS standard and On board system can be implemented the function by standard too. On this point of view, this paper is to review the standard of level transition for ERTMS to STM(TVM) and investigate the implement of domestic line.
