A Simulation of the Railway Signal System Using Pattern Control Technique to Upgrade the Railway Efficiency

선로효율 향상을 위한 열차 패턴제어방식의 신호보안시스템 시뮬레이션

To upgrade railway traffic density without any change of signal block length between stations on existing railway lines, a new signalling system of train control "the pattern control technique" is suggested. It needs very little change to computerize the cab signal using transponders. A computer simulation system is developed to experiment the new control method. The new signalling system shows much increase of the railway traffic efficiency. The train head-way time by the fixed signalling system and the new pattern control system is analyzed. The pattern control technique shows 35% increasement of trair operation under same condition of railway and trains.nd trains.
