CBTC시스템의 열차위치 보정 및 재검지 방법

In order for CBTC(Communication Based Train Control) control system to control a train periodically through wireless communication, wayside signal equipment compensates the train position and sents more detail train control informations to onboard signal equipment. If communication between the wayside and onboard signal equipment is failed by the failure of train control system and wireless communication equipment, the train sets related area as a protection zone for safety. then when the failure is released, train automatically starts re-detection.
