Abstract

Subway station scales are determined by peak predictions. In this study, the purpose behind the installation of a subway is public transportation convenience and public interest, but economic validity is also important. By proving that the scale of the station is excessive with regard to the target station size for Seoul subway Line 5-8, a reasonable plan. can be sought. According to station installation standards, the area of the station under investigation here is out of the service levels by six stages (A~F), and it must be four or more levels (D). The Actual level for the B level is a two-step design. The Actual ratio for over- Peak predictions is only 17.8% on average. The results of measurements of the excess area and determination of the excessive costs were analyzed by subdividing the area and by calculating it based on the B level, finding that it is possible to provide benefits for customers only in the current design, with an area ratio of 16.3%. Given the weight, it was estimated that current conditions can meet the needs of only 18.6% of the current area. Simplifying the scale calculation method of the station, it is convenient, safe, and advantageous to move citizens only if the scale can be streamlined. Then, with a reduced initial investment, maintenance costs during the operation can be reduced.

지하철 정거장면적의 규모를 세분화하여 분석한 결과 이용승객 실적을 기반으로 B수준으로 면적을 산정하면, 현재 건설된 면적대비 16.3%만으로도 고객의 이용 편익을 충족시킬 수 있다. 그리고 정거정별 위치와 지명도, 상징성, 하루 승 하차인원 등 역별 특성에 맞게 가중치를 부여하면, 현재면적의 18.6%만으로도 수요를 충족할 수 있는 것으로 추정되었다. 호선별로 보면 8호선의 과다면적이 가장 크고, 환승유 무별에서는 환승역이 비환승(일반)역보다 과다면적이 크게 추정되었다. 그리고 지하 심도별로는 21~30m인 역의 면적이 가장 과다하고, 승차인원별 추정에서는 1일 피크실적 1,000명 이하의 역들이 가장 과다면적이 큰 것으로 추정되었다. 정거장의 규모(면적) 산정방식을 단순화하고 규모를 슬림화(축소)하는 것이 시민들의 이동편리(동선, 이동시간)와 지하공간이동 안전에 유리하고, 초기투자비 절감 및 운영시 유지관리비용 절약에서도 효과적일 수 있다.
