개인의 생애주기 단계에 따른 통근시간 영향요인 분석 -- 2010년 수도권 가구통행실태조사자료를 중심으로 -

초록

This study examines the determinants of commuting time by individuals’ life cycle stage. We have applied the 2010 household travel survey data of the Seoul metropolitan area and the multi-level regression model. The results of this study are as follows. First, the multi-level regression models show that the levels of household and neighborhood explained the variation in commuting time in terms of 16-20% and 2-5%, respectively. This finding indicates the importance of controlling for household and neighborhood characteristics in commuting time studies. Second, this study identifies the determinant factors of commuting time by different life cycle stages. In particular, individuals at the life cycle stage before independence from their parent households showed the longest commuting time. In contrast, individuals in the middle-age households with school children showed shorter commuting time. Third, the results show that an individual’s commuting time was highly associated with mode choice, housing type, household income and the housing price of their job locations. The results of this study are useful for development of housing and transportation policies to enhance jobs-housing balance and reduce commuting time based on individual’s life cycle stage.
