城市出行行为的研究通常集中在工作日的活动和通勤。这是令人惊讶的，因为在过去的几十年里，自由支配的活动对日常旅行的贡献越来越大。此外，目前的旅游行为和土地利用之间的关系的理解仍然是不完整的，很少进行研究，以探索在非高峰期和周末时间段的活动旅行行为的空间特性。例如，周末行为受时间可用性和“周末”目的地时空分布的影响，可能会产生空间和时间上不同的活动旅行模式。使用数据的第一波的多伦多旅游活动面板调查（TTAPS），本文探讨了一个领域的研究，很少受到关注，即存在的空间多样性的活动旅游行为。本文首先着眼于在何种程度上个人从事在空间上重复的位置选择在一个星期的过程中。基于区域的地理范围和活动分散的措施，然后使用暴露在工作日到周末和日常的活动旅行模式的差异。在1周内进行的未分类的活动的检查揭示了一个水平的空间重复，并没有实现跨活动分类的类型，旅行模式和规划策略。尽管私人汽车提供了固有的空间灵活性，但空间重复也被发现在不同的旅行模式中惊人地相似。研究结果还表明，工作日到周末，每天的个人活动旅行行为的空间特性的波动。这些发现挑战的实用程序的短期调查作为一种工具，捕捉原型模式的空间行为。此外，空间行为存在工作日与周末的差异，这表明旨在减少工作日旅行的政策对与周末活动有关的旅行几乎没有影响。
Studies of urban travel behaviour typically focus on weekday activities and commuting. This is surprising given the rising contribution of discretionary activities to daily travel that has occurred during the last few decades. Moreover, current understanding of the relationship between travel behaviour and land use remains incomplete, with little research carried out to explore spatial properties of activity-travel behaviour during the off-peak and weekend time periods. Weekend behaviours, for example, influenced by the availability of time and the spatiotemporal distribution of "weekend" destinations, likely produce spatially and temporally distinct activity-travel patterns. Using data from the first wave of the Toronto Travel-Activity Panel Survey (TTAPS), this paper examines an area of research that has received little attention; namely, the presence of spatial variety in activity-travel behaviour. The paper begins by looking at the extent to which individuals engage in spatially repetitive location choices during the course of a single week. Area-based measures of geographical extent and activity dispersion are then used to expose differences in weekday-to-weekend and day-to-day activity-travel patterns. Examination of unclassified activities carried out over a 1 week period reveals a level of spatial repetition that does not materialise across activities classified by type, travel mode, and planning strategy. Despite the inherent spatial flexibility offered by the personal automobile, spatial repetition is also found to be surprisingly similar across travel modes. The results also indicate weekday-to-weekend, and day-to-day fluctuations in spatial properties of individual activity-travel behaviour. These findings challenge the utility of the short-run survey as an instrument for capturing archetypal patterns of spatial behaviour. In addition, the presence of a weekday-to-weekend differential in spatial behaviour suggests that policies targeting weekday travel reduction could have little impact on travel associated with weekend activities.
