Abstract

The purpose of this study is to evaluate vertical moving facilities at subway stations for the elderly users and to analyze their improvement measures. To evaluate vertical moving facilities of the top 31 subway stations with the most trips in Seoul, a data envelopment analysis (DEA) is employed. The input variables for the DEA include the number and percentage of elderly users, which are calculated using smart card data. the output variables consist of the number of elevators and escalators per 100 steps. The results show that the average score of 31 subway stations is 0.62 and four stations, i.e., Jamsil, Gasan Complex, Konkuk University, and Dongmyo, have the highest score. These four subway stations are set as benchmarking groups for the other stations with the lower score. Based on the comparison with the benchmarking groups, the improvement measures for vertical moving facilities of each station are suggested and discussed.

본 연구는 고령자를 위한 지하철 역사의 수직이동시설을 평가하고 개선방안을 분석하는 것을 목적으로 한다. 서울시의 통행량이 많은 31개의 지하철 역사를 평가하기 위해 자료포락분석(DEA)을 이용한다. DEA의 투입변수는 스마트카드 자료를 이용하여 수집한 고령자 통행수 및 통행비율을 포함하며, 산출변수는 엘리베이터 설치 대수와 100계단 당 에스컬레이터 설치 대수로 구성된다. 분석 결과, 31개 지하철 역사의 평균 지수는 0.62로 산출되었으며, 잠실역, 가산디지털단지역, 건대입구역, 동묘역이 가장 우수한 것으로 나타났다. 이 4개의 역사는 지수가 낮은 다른 역사들을 위한 참조 그룹으로 설정된다. 참조그룹과의 비교를 통해 각 역사의 수직이동시설을 제고하기 위한 방안들이 제안된다.
