초록

철도노선은 도로노선과 달리 운행비용, 특히 에너지비용이 전체 생애주기 비용에서 차지하는 비중이 높은 것으로 알려져 있다. 본 연구에서는 경부고속철도의 사례를 중심으로 철도 노반건설비와 에너지비용의 상대적 비중을 분석하였다. 이는 최근 활발하게 연구가 이루어지고 있는 전산화된 철도선형 최적화가 단순히 건설비 최소화만을 목적으로 할 수 없으며, 에너지 비용을 포함한 전반적인 생애주기 비용의 최소화를 목표로 하여야 함을 의미한다. 경부고속철도 운행실적이 아직 10년에 불과하기 때문에 향후 20년간의 운영 시나리오를 다양하게 설정하여 분석한 결과, 에너지비용이 건설비용의 10~30% 수준으로 나타났으며, 이는 일반적으로 알려진 비중보다 낮은 수치이다. 철도 선형 최적화를 위한 방법론 정립에 있어 에너지 비용을 고려할 경우, 그 상대적 비중을 고려할 수 있는 방안을 제시한데 본 연구의 의미가 있을 것이다.

It is generally recognize that the weight of energy cost for railroad alignment in the life cycle cost is higher than that for roadway. This study analyzed the relative weights of railroad road-bed construction cost and energy cost in the case of Seoul-Pusan High Speed Rail. Recently, the optimization of railroad alignment with computerized methodology has been studies. The optimization is supposed to aim the minimization of life cycle cost including the energy cost as well as the minimization of the construction cost. The operation period of the Seoul-Pusan High Speed Rail is limited to ten years, then various future operation scenario were developed for the next 20 years. The weight of energy cost is estimated 10~30% of the construction cost by scenario, and it is lower than the figure generally expected. It may be meaningful to provide the method to include the energy cost in the railroad alignment optimization.
