Function model of train control system for unmanned operation of urban transit system

The train control system (TCS) plays the core role to secure the safety and punctuality for railway train operation. There are various systems applied to urban transit lines which are developed differently and independently from other countries. The national standard specifications and guidelines have been established and maintained for the TCS in Korea. As the requirements of the high-efficient and economic operation of the urban transit system is getting higher, the unmanned operation of the train is moving to the limelight. Lots of systems supporting unmanned operation are being applied to the new lines such as Yongin, Busan (3^rd line), Incheon (2^nd line) and so on. The standard of the TCS for urban transit supports the system for unmanned operation as requirements. The function model of TCS has been established on the basis of the standard specification to analyze the requirements and behavior of the TCS. The model is also to support the test and evaluation of the system to be operated with the unmanned through the standard.
