Abstract
PurposeThis study analyzes the relationship that land use has with weekend travel in comparison to weekday travel. Unlike previous studies, it uses the same sample for two models that are specified to test the relationship separately for weekday and weekend travel.MethodsStructural equation modeling is employed to test the land use–travel relationship. A comparison is made using two mode-specific travel measures: trip frequency and travel time.ResultsOn weekday travel, land use in Seoul tends to reduce automobile trips and to add transit and nonmotorized trips. This does not lead to a reduction in the total frequency of weekday trips. Instead, an overall reduction occurs in the frequency of weekend trips because the addition of transit and nonmotorized trips is less than the reduction of automobile trips.ConclusionsThe application of structural equation modeling to a Seoul household travel survey confirms the opposing role of land use in travel mode choices on weekdays versus weekends.
Highlights
Transportation studies have traditionally dealt with weekday travel [1]; relatively few studies on weekend travel have been conducted [2, 3]
A larger amount of travel occurred on weekends than on weekdays regardless of the mode used and of the travel measure, be it trip frequency or travel time
The models were constructed for weekday and weekend travel, each of which was again separated to measure both trip frequency and travel time
Summary
Transportation studies have traditionally dealt with weekday travel [1]; relatively few studies on weekend travel have been conducted [2, 3]. From the late 2000s, studies began to analyze weekend travel and weekday–weekend differences in order to fill this gap [e.g., 4]. Few studies looked at how weekend travel is related with land use variations, though they have been called for [5, 6]. This topic is increasingly important because urban residents have exhibited a greater tendency to embark on weekend travel in recent years [7, 8], for which trip destinations and. This study analyzes the land use–travel relationship on weekends and examines how it differs from the relationship on weekdays, using a case of Seoul, South Korea. The correlation between land use independent variables—for example, dense neighborhoods usually have extensive road networks and many transit facilities—is called spatial multicollinearity and requires classical statistical methods such as regression
