Abstract

A direct demand model requires relatively little analysis time and incurs a low cost. It is also known to be useful for the preliminary screening of promising configurations or concepts. This study reviews direct demand models of 12 existing urban railways using demographic data based on a block group level which is approximately 1/24 of a traditional zone area. However, direct demand models are limited. Therefore, a new approach is suggested. The proposed method is based on a field study and an empirical analysis. The study finds factors that affect ridership at the station level. As a case study, the proposed approach is tested using 54 light railway transit stations. The results of this empirical study demonstrate its applicability to improve the error rates of the predicted ridership at the station level.

직접수요모형은 전통적 4단계 수요예측방법론보다 적은 비용과 시간으로 기본구상단계에 적합한 분석방법이다. 본 연구에서는 기존 읍면동 기준보다 약 1/24 공간적 크기를 가진 소지역(집계구)단위 사회경제지표를 활용하여 지방 광역권 12개 도시철도 노선을 대상으로 직접수요모형을 구축하여 예측수요를 실적자료와 비교 분석하였다. 하지만 통계적 분석에 의존하는 직접수요모형은 역별 특성을 반영하지 못하여 승차인원 예측에 한계가 있으며 본 연구에서는 승차인원에 영향을 미치는 인자를 찾아내고 각 영향인자들의 표준화 및 기준을 제시하였다. 특히 사회적 이슈가 되고 있는 경전철 노선 54개 역을 대상으로 실증분석하여 역 특성 기초자료 수집, 분석, 보정방안에 대해 논의하였다. 경전철 역을 대상으로 제안된 방안의 적용성을 검토하였고 향후 직접수요모형의 활용성을 높일 수 있을 것으로 기대된다.
