Abstract

New Opening of Suseo-Pyeongteak High Speed Railway (HSR) will be a new leap in the Korean railway history. However if this section of HSR line around Seoul Metropolitan Area opens, the confluence of new HSR and existing HSR line in Pyeongteak-Osong section will cause a bottle neck problem. In other words, the opening of Suseo-Pyeongteak HSR line will make the capacity of track reach the limit and the section of railroad between Pyeongteak and Osong will be saturated. This will also make such troubles as restricting the number of train which stops at Cheonan-Asan station. In this study, based on the train assignment theory of TVM430 signal system, the methods of calculating headway and number of train are reviewed and the plan for application of optimal operation pattern during peak hour between Pyeongteak-Osong section is also suggested. To remove the bottle neck problem in this HSR section, 3 alternatives are suggested and the expected effects and problems of each alternative are also analyzed. The results show that the troubles caused by excess of track capacity can be removed without any additional cost if the minimum headway in operating system for HSR is adopted in this section. In the future, if these alternatives are considered to the long-term plan for operating train and signal systems, this will improve the efficiency of train operation, which can remove the bottle neck in the HSR line.

수서-평택간 수도권과 호남고속철도 1단계사업이 2014년 말 개통됨에 따라 고속철도의 제2의 도약을 맞이하게 되었다. 하지만, 수도권 고속철도 건설기본계획에 준해 고속열차가 설정될 경우 수도권 고속열차와 기존 고속열차의 합류지점인 평택-오송 구간에서 고속선 선로용량의 최대치에 도달하게 되는데, 이로인해 천안아산역의 정차열차 수를 제한을 받게 되며 장기적으로 열차수요가 늘어나면 고속열차를 추가설정 할 수 없는 제약요인으로 작용이 예상된다. 본 연구는 고속선의 신호체계인 TVM430시스템의 열차설정 이론을 기초로 운행시 격 및 열차횟수를 산정방법을 검토한 후, 첨두시간대 병목구간인 평택-오송간의 최적의 열차운행패턴 적용방안을 제시하였다. 또한 적용방안을 운영에 도입할 경우 기대되는 효과와 문제점을 대안별로 분석하여 현 여건에 맞는 단계적 정책대안을 제시하였다. 분석결과 현재의 고속열차 운영시스템에 최소운행시격을 설정하여 병목구간을 운행한다면 추가투자비용 없이 선로용량초과 문제를 해결할 수 있을 것으로 사료된다. 향후 중장기 열차운영계획 등에 대안들이 반영된다면 고속선 병목구간(MLP, Maxmum Load Point)해소 등 열차운영효율 향상에 기여 할 것으로 기대된다.
