The Impacts of Shoulder Days on Non mandatory Activity Duration: A Time-Use Analysis Based on 2009 NHTS Survey
This study is intended to explore the temporal variations observed in non-mandatory activity involvement from a time-use analysis perspective. Five non-mandatory activities including “Household maintenance”, “Personal maintenance”, “Social”, “Meal” and “Exercise” are examined in terms of activity duration. More importantly, this study emphasizes on the impacts of shoulder days (Mondays and Fridays) on non-mandatory activity duration as there has been a tendency to ignore the roles of these two days of the week compared to typical mid-weekdays. A structural equations model (SEM) is developed to investigate 1) How non-mandatory activities compete with each other in view of time budget allocation, 2) How activity durations very across different segments (days) of the week, and 3) How observed differences could be correlated with socioeconomic and demographic attributes. Temporal variations are captured through the incorporation of a weekday category variable (Monday, Midweek, and Friday), and the associated interaction effects with various personal and household characteristics. The model results reveal significant interaction effects, confirming the hypothesis that people do show temporal preferences on shoulder days compared to typical mid-weekday for non-mandatory errands. The data applied in this study was obtained from the 2009 National Household Travel Survey (NHTS).
