Abstract

The Seoul Metropolitan Subway, which started operating in 1974, plays a major role in transporting 7,289 thousands passengers daily. This trend of a steadily increase in passengers from 2012 has increased the congestion rate because of the limited capacity and time. To solve this problem, Seoul city is consistently working on improving the subway facilities, such as the construction of a detour path. This project, however, has only a slight effect on improving the congestion rate and is too expensive to construct the facilities. Hence, this study suggests The Congestion Standardization System based on the IoT for improving the subway congestion rate. Based on the system, the expected effect analysis was performed, which resulted in a decrease in ride passengers from 34 to 20. In addition, this expected effect analysis shows that the number of subway vehicles can increase from 20 to 24. The suggested system will have a significant effect on the efficiency of the management system.

수도권 지하철은 1974년, 서울 1호선 개통을 시작으로 현재 일일 7,289천 명을 수송하는 가장 중요한 교통수단 역할을 하고 있다. 이처럼 서울 지하철은 2011년 이후 지속적으로 증가하는 수송인원을 처리하고 있지만, 제한된 지하철 용량과 배차시간 때문에 지하철 내의 혼잡도는 계속 증가하고 있는 실정이다. 이에 서울시는 서울역, 시청역, 교대역 등 12개의 역사에 우회통로 건설 등의 혼잡역사 구조 개선사업을 시행하고 있다. 하지만 이러한 사업은 한 역사 당 평균 186억 원의 대규모 공사비에 비해 미미한 개선 효과를 보이면서 혼잡도 개선을 위한 차선책이 필요한 실정이다. 따라서 본 연구는 효율적인 객차 및 역사 내 혼잡도 완화를 위해 IoT를 접목한 혼잡도 평준화 시스템을 제안하였다. 제안한 시스템을 바탕으로 예상 효과 분석을 진행하였고, 분석 결과 한 객차에 승차하는 인원이 기존 34명에서 최대 20명으로 감소되는 효과가 나타났다. 이와 더불어 기존 첨두시 20대의 열차 운행대수가 24대로 증차될 수 있다고 분석되면서 운영 효율성 측면에서 효과가 있을 것으로 사료된다.
