Abstract

This paper proposes an analytical methodology of station capacity calculation on high - speed railway. Our method explicitly takes into account the effect of the number of sidings and the combination of train halting patterns (stop - stop, pass - stop, stop - pass, pass - pass) on the capacity of a station. To verify the reliability of our model, we conducted capacity analysis of selected stations using the Railsys simulator. We found that the difference in calculated capacity between our model and Railsys was less than 10%. After Monte Carlo simulation, our model was determined to be a good one. In addition, the consistency in capacity between our model and the train-path allocation program (Korea Rail Network Authority) was statistically significant.

본 연구에서는 산식에 기반 한 고속철도 정거장 선로용량 계산 방법론을 제시하였다. 제시한 방법론은 기존 방법론에서 명시적으로 다루지 못하였던 정거장별 부본선(정차본선) 설치 수와 정차패턴(정차-정차, 통과-정차, 정차-통과, 통과-통과)의 혼합이 선로용량에 미치는 영향을 반영한다. 제시한 선로용량 계산 결과의 일관성을 검증하기 위해 전문 시뮬레이터(Railsys)를 활용하여 비교한 결과 정차패턴별 시격의 차이는 10% 미만으로 분석되었다. 정차패턴이 조합되었을 때의 효과를 몬테카를로 시뮬레이션 한 결과 역시 계산된 선로용량은 현실성이 높은 것으로 판단된다. 또한, 한국철도시설공단 선로배분프로그램의 용량산정 결과와도 통계적으로 유사하였다.
