Travel time budgets: new evidence from multi-year, multi-day data

The Regularity and Irregularity of Travel: An Analysis of the Consistency of Travel Times Associated with Subsistence, Maintenance and Discretionary Activities

“…Metz (2008) noted that an "improvement in the transport system allows further access to desired destinations, within the more or less constant time people allow themselves on average for travel" (Metz (2008): 333). This paper and those that focus on differences across types of days, such as Bhat and Misra (1999); Yamamoto and Kitamura (1999), Holden and Linnerud (2011) and Stopher et al (2016), are relevant to this discussion as a focus on everyday travel has meant that transport policy and research have not fully considered the implications of the different travel patterns that occur between discretionary and non-discretionary days. For example, the literature on the value of travel time has tended to focus on variations based on the time of the day on weekdays (Small, 2012), even though early work had focused on differences between weekdays and weekends (Horowitz, 1978).…”

“…An example of these unintended consequences is the reduction of the average trip length that induces additional demand for leisure travel on weekends or holidays. Recently, Stopher, Ahmed, and Liu (2016) reviewed average travel time expenditures and found that there was greater variability on weekends than weekdays and all days of the week. In this study, they noted that "this is a new finding, because weekend days have not been the subject of prior research on travel time expenditures/budgets" (Stopher et al, 2016).…”

Analysis of Potential Shift to Low-Carbon Urban Travel Modes: A Computational Framework Based on High-Resolution Smartphone Data

“…Here, essential factors to take into account for understanding modal shift potential are reducing emissions and increasing physical activity for individual travelers [3,4]. However, the potential shift away from passenger car use has to account for constrained daily travel time budget and activity space [5,6]. Specifically, understanding potential for modal shift requires comparing travel times of alternative modes for individual travelers, as they can influence travelers' decisions [7].…”

Analysing the Effects of Land Use on the Choice of Intra-Zonal Trip Destinations – A Comparison Between Weekday and Weekend Travel

“…In particular, between two concepts that constitute the relationship, first, regarding land use (or for transportation planners who consider an effective land use intervention), a long-standing question is which variable is crucial among different land use variables [6,7]. A second, more critical issue is related to travel behaviour: most previous studies were concerned with weekday travel [8][9][10][11], so in terms of external validity, the general significance of the land use -travel relationship can be concluded only on weekday travel, that is, in fact, little is known about weekend travel. Studies based on weekday travel may be limited in offering implications in understanding the relationship that land use has with weekend travel [6,[12][13][14][15] and thus, studies have been requested to use weekend data to examine the land use -weekend travel relationship [16].…”
