A Study on Minimization of Train Delays and Train Operation Interruptions by RF Transmission System.

RF 통신시스템을 이용한 열차 운행중단 및 열차 지연의 최소화에 관한 연구

To minimize the train operation interruptions and train exchanges, the RF transmission system is proposed. The current control room of the Seoul Metro has information of the train movement through the Total Traffic Control System, but it does not have information of the train itself, rail status, and other facilities' status. When some trouble occurs during train operation, the train crews should report the control room about the trouble and fix it. If the control room has exact information of the trouble, the expert in the control room can help the crews to fix the trouble swiftly and exactly. Since the crews are busy taking care of the trouble, they often miss to report the control room on time. The proposed RF transmission system relays the information of the train to the control room automatically in real time, and makes it possible to provide the passengers good service by reducing the train operation interruptions and train exchanges.
