Automatic Train Supervision (ATS)

ATS is a comprehensive train operation control system that fully automates train operation handling (signal control) using a control program based on the Train Schedule Diagram. The central systems consist of a Train Control Computer (TCC), a Management Support Computer (MSC), an Operator Console, Data Transmission System (DTS), a large display panel, and various peripherals. STraffic has established and maintained the Seoul Metro Line 2 and is developing our own ATS solution optimized for the KRTCS (CBTC for Korean).
