Abstract

This study suggested the ARIMA model taking into consideration the seasonal characteristic factor as a method for efficiently forecasting passenger transport demand of the Joongang Line. The forecasting model was built including the demand for the central inland region tourist train (O-train, V-train), which was opened to traffic in April-, 2013 and run in order to reflect the recent demand for the tourism industry. By using the monthly time series data (103) from January-, 2005 to July-, 2013, the optimum model was selected. The forecasting results of passenger transport demand of the Joongang Line showed continuous increase. The developed model forecasts the short-term demand of the Joongang Line.

본 연구는 중앙선의 여객수송수요를 효율적으로 예측하기 위한 방법으로 계절성 요인을 고려한 ARIMA 모형을 제안하였다. 특히, 최근의 관광수요를 반영하기 위하여 2013년 4월 개통되어 운행되고 있는 중부내륙권 관광전용열차(O-train, V-train)의 수요를 포함하여 예측모형을 구축하였다. 이를 위하여 2005년 1월부터 2013년 7월까지의 월별 시계열 데이터(103개)를 사용하여 최적의 모형을 선정하였으며 예측결과 중앙선의 여객 수송수요는 지속적으로 증가할 것으로 나타났다. 구축된 모형은 중앙선의 단기수요를 예측하는데 활용이 가능하다.
