초록

이 연구는 우리나라에서 현재까지 사용되어 온 (수단O/D기반)화물수요추정법의 문제점 인식을 바탕으로 P/C기반 화물수요추정법과 비교 분석을 수행하였다. 우리나라 화물수단O/D는 화물의 최초기점과 최종종점 간 운송을 수단별 통행으로 나누어 인식하면서 접근트럭통행(Access/Egress Truck Trip)에 대한 정보가 누락되어있다. 이러한 이유로 수단O/D기반 화물수요추정법은 화물의 복합수단운송을 반영하지 못하는 단점이 있다. 이에, 본 연구는 우리나라 컨테이너 화물을 중심으로 P/C표와 복합수단선택모형을 추정하여 P/C기반 화물수요추정법을 제시하고, 기존 사용되어 오던 수단O/D기반 화물수요추정법과 기종점쌍 간 전환량, 수단통행물동량, 링크물동량을 비교하였다. 비교 결과 P/C기반 화물수요추정법은 복합운송을 제대로 모사하지 못하는 기존 수단O/D기반 화물수요추정법의 문제점을 해결할 수 있는 것으로 평가되었다.

This study deals with the comparative analysis between two freight demand estimation methods : Unimodal O/D based method and P/C based method. The data of access/egress truck trips has been omitted from the Korean freight unimodal O/D of KTDB. This is because KTDB's unimodal O/D has not marked the series of unlinked trips down as the whole freight intermodal transport and surveyed only the main-haul trips of them. For these reasons, freight intermodal transport mechanism has not been analysed perfectly with Korean unimodal O/D data. This study tries to estimate P/C table of Korean Import/Export container freight and develop the MCC(Multimodal Channel Choice) model. Then, comparing unimodal O/D based method and P/C based method in terms of the switch commodities between production point(the initial point of freight transport) and consumption point(the terminal point of freight transport), unimodal commodities, and commodities on links is conducted. The results show that the P/C based method is able to simulate the freight intermodal transport.
