【摘要】This study aims to provide empirical evidence for two traditional research questions in the field of telecommuting studies: (1) Does telecommuting promotes dispersion of urban space? (2) Does telecommuting substitute for household travel?Although these causality issues have received great deal of attention; no multivariate analysis approaches exist. Using the 2006 household travel survey data from the Seoul Metropolitan Area; this study adopts a path analysis to discover the complex relationships between telecommuting; residential/job locations; and household travel.First; the path analysis shows that rather than telecommuting serving as the determinant of location choice; job locations determine the choice to telecommute. Hence;secondary impacts of telecommuting on travel may not occur with location changes as the medium. Second; the analysis also shows that the household head’s telecommuting has a positive influence on his/her non-commuting travel in both the person kilometers traveled (PKT) and vehicle kilometers traveled (VKT) models and on household members’ travel in VKT models. Moreover; the VKT model suggests that the household head’s non-commuting travel has a negative impact on the household members’ travel.These results indicate that although telecommuting reduces commute travel; this may be offset by other travel demand within the household; owing to exhaustion of the limited travel budget. Thus; planners and policymakers must consider these impacts when evaluating the benefits and costs of telecommuting as an urban management policy.
