Abstract
Weekend travel has not been duly considered in academics and practice regarding its relationship with land use. A lack of consideration is notable in terms of how land use internalizes weekend travel. Thus, by separating the internal and external travel of the traffic analysis zone, this study analyzes the land use effect on weekend travel in comparison with that on weekday travel. Two structural equation models, each of which is specified for weekday and weekend travel, construct the same sample and their results become comparable. At the travel variable level, the models find consistent results: Stronger effects are made on internal travel than on external travel and particularly, on trip frequency than on travel time. This implies that compact land use causes a stronger addition of internal trips and a less strong reduction of external trips, that is, changes in destinations rather than in total travel time. At the factor level, unlike the weekday model in which the sociodemographic factor exerts a stronger effect, the weekend model presents that land use more strongly affects travel patterns. This magnitude difference is explained by the different flexibility of compulsory weekday travel and discretionary weekend travel in relation to the choice of trip destination and frequency.
Highlights
Defined as travel on Saturdays and Sundays that are not holidays and vacations [1,2], weekend travel mostly has non-commuting purposes such as sightseeing, social, recreational and sports activities [3]
Weekend travel differs from weekday travel but few have investigated its characteristics, with regard to the effect that land use has on weekend travel
This study aimed at analyzing the land use effect on weekend travel as well as on weekday travel through structural equation modeling (SEM), focusing on destination choice or trip internalization, a topic that has been barely studied in relation to weekend travel
Summary
Defined as travel on Saturdays and Sundays that are not holidays and vacations [1,2], weekend travel mostly has non-commuting purposes such as sightseeing, social, recreational and sports activities [3]. This study aims to analyze the relationship between land use and weekend travel in comparison with weekday travel. (Due to data limitations, this study will measure the individual factor only with sociodemographic variables, not with attitudinal variables attitudes have often been reported to strongly affect travel patterns [14,15,16].) the hypothesis of the study is: As compared with the effect of the reference factor of sociodemographics, the land use effect is stronger on weekends than on weekdays. Ewing and Cervero’s meta-analysis [17] found that the magnitude of the land use–travel relationship hinges partially on the travel measure itself They reported that land use has a smaller effect on trip frequency than on total travel distance (as a composite measure). To empirically examine the land use–weekend travel relationship, this study extracts travel data from the weekend survey of the KHTS. Land use variables are evaluated with GIS (geographic information systems) datasets
