Abstract

In this study, we numerically estimated available and unavailable time of conventional railway by examining 60% which is known as average range of track utilization efficiency. We also estimated track repair time for maintenance which is the main factor of making track utilization change and analyzed appropriate estimated time. The railway's safety should be guaranteed by appropriate railway operating plan and by adequate rail facilities maintenance. At the same time, daily railway train 'Dia's recovery power should be reflected to the management plan. Considering these factors, we examined mechanical equipment and the national rail network in order to rationally estimate track repair time of the maintenance and to secure spare time in case of train delays. It was found that track utilization efficiency was more or less 60%.

본 연구에서 일반철도의 선로이용율의 범위인 60%를 검토하여, 이용가능한 시간과 이용 불가능한 시간을 수치화 하였다. 또한 선로이용율을 변화시키는 요소인 선로유지보수시간에 대한 계산과 적정한 추정시간을 분석하였다. 적절한 철도운영계획과 원활한 시설유지보수를 통한 열차의 안전을 보장하여야 한다. 동시에 매일 연속되는 열차Dia의 원상회복력도 운영계획에 반영되어야 한다. 이런 사항들을 고려하여 보유 중인 기계장비와 국가철도망에 대한 자료를 활용하여 유지보수작업시간 산출방법을 개선하고, 열차지연에 대비한 여유시간을 확보하도록 검토하였다. 결론적으로 일반철도의 선로이용율과 선로유지보수시간 구성요소를 함께 수량화하여, 선로이용율은 60% 내외가 타당함을 증명하였다.
