Abstract

For the demand analysis of Metropolitan Train Express project, the catchment area of station should be reevaluated considering the journey speed of it. In this paper, we estimated travel mode choice model using stated preference data including Seoul metropolitan express train and compared the parameters of access/egress travel time between existing metro and Seoul metropolitan express train. The parameter of Seoul metropolitan express train is 2.5 times smaller than that of existing metro. Consequently, the catchment area can be expanded in same proportion. It can be concluded that the result of demand forecasting can be increased by 10% accommodating the expanded catchment area.

수도권 광역급행철도 사업의 추진에 따라 해당 사업의 수요분석에 있어서 철도역의 영향권 설정 문제가 대두되었다. 이에 본 연구는 수도권 광역급행철도의 특성에 부합하는 철도역 영향권 설정방안을 제시하였다. 선행연구 및 접근통행 실태조사를 통해 노선의 특성 및 접근수단에 따라 영향권이 달라질 수 있음을 확인하였고, 광역급행철도를 별도의 수단으로 하는 수단선택모형을 구축하고 수단별 접근시간 모수추정치를 비교하였다. 이를 통해 광역급행철도의 영향권이 기존 광역도시철도에 비해 2.5배 가량 확대될 수 있음을 보였다. 이는 수요분석에 있어서 10% 이상의 차이를 낼 수 있어서 향후 수도권 광역급행철도의 합리적 수요분석을 위해서는 확대된 영향권의 설정이 필요하다고 하겠다.
