기존선 속도향상을 위한 신호시스템 구축방안 연구

초록

Some train operation companies consider to speed up their conventional lines using ATS(Automatic Train Stop). But this is effected by track environment, signal distance and train braking distance. And ATS needs to improve reliability and safety of train operation, train capacity and so on, As a result of these related facts, onboard signaling systems such as ATP(Automatic Train Protection) are installed on conventional lines, and being considered by some train operation companies. However the onboard signaling system is overlaid on the conventional track with ATS, it is necessary to make a study on the selection of signaling system and interface between ATS and the onboard signaling system. The onboard signaling system can include ATC(Automatic Train Control) of KTX and ETCS(European Train Control System) level 1&2. And the safety effect of train braking distance and signal aspects must be analyzed to link ATS and the onboard signaling system. This paper includes guideline lines for the selection of onboard signaling system and constitutional directions of onboard signaling system on conventional lines.
