Abstract

When constructing railway stations, gates shall be located in appropriate locations for convenient use. However, to reduce construction costs, the number of gates was minimized and the location was not appropriately placed to the direction of many users. This study proposed a method to calculate the benefits of additional gate installations using the improvement of pedestrian traffic flow, occupied area and travel time as economic effects. In particular, a method of estimating the percentage of people using certain gates and the number of people by route within the station was proposed. This method was applied to analyze the effect of additional gates to Gwang-myeong Station on the Shinansan Line, which is to be opened in 2025. The effect has only improved in mobility. The first year of its opening was estimated at 5.91 billion won for mobility and 75.8 billion won for cost, and the B/C was 1.21 for 30 years after its opening. It is expected that this method will be applied to systematic effect analysis when additional gates are installed at unopened railway stations as well as existing railway stations.

철도역을 건설할 때 출입구는 많은 사람이 편리하게 이용할 수 있도록 적절한 위치에 배치되어야 한다. 그러나 건설비용 절감을 위해 출입구 설치 개수가 최소화되고 설치 위치도 이용자가 많은 곳에 배치되지 못하였다. 본 연구는 출입구 추가설치 시 경제적 효과로 보행교통류율, 점유공간, 이동(대기)시간 개선 정도를 이용하여 편익으로 산정하는 방법을 제시하였다. 특히, 개통되지 않은 철도역사의 외부에서 사람들이 특정 출입구를 이용하는 비율과 역사 내부에서 이동 경로별 이용자 수를 추정하는 방법을 제시하였다. 이 방법을 적용하여 실제 2025년 개통 예정인 신안 산선 광명역에 출입구를 추가로 설치할 때 효과를 분석하였다. 효과는 이동성만 개선되었다. 개통 첫해 이동성 개선 약 5.91억 원, 설치비용 75.8억 원이 산정되었고, 경제적 효과는 개통 후 30년 동안 B/C 1.21로 나타났다. 향후 기존 건설된 철도역뿐만 아니라 미개통된 철도역에서도 출입구를 추가로 설치할 때 이 방법을 적용하여 체계적인 효과분석이 가능할 것으로 기대된다.
