个人建立稳定的、相对固定的出行模式的想法一直是交通研究人员方便、令人信服和广泛采用的假设。如果高度抽象化的习惯性行为确实存在，那么它将受到欢迎，因为它易于预测，而且只需要对这种行为的快照就可以在调查中充分捕捉到它。问题一直是要定义什么样的观察期才能让我们看到行为没有净变化。本文首先讨论了活动空间的各种度量（椭圆和核密度），然后分析了Mobidrive和乌普萨拉数据库，每个数据库分三个两周（第1周和第2周;第3周和第4周;第5周和第6周）。然后，使用各种社会人口变量对这些措施进行分析，并研究是否存在某些特定的模式。研究结果表明，人们（主要是全职工作者）在工作日形成稳定的旅行模式，但在周末，他们寻找各种休闲机会，因此他们的旅行模式更具变化性。
The idea that individuals establish stable, relatively fixed travel patterns has been a convenient, compelling and widely adopted assumption among transport researchers. If highly routinised habitual behavior was to exist, then it would be welcomed, for its ease of predictability and for the fact that only a snapshot of such a behavior would be needed to capture it adequately in a survey. The problem has always been to define what should be the period of observation in which we can see no net change in the behavior. This paper first discusses various measures of activity spaces (Ellipses and kernel densities) and then analyses the Mobidrive and the Uppsala databases in three blocks of a fortnight each (weeks 1 and 2; weeks 3 and 4; weeks 5 and 6). Then the measures were analysed using various socio demographic variables and studied if certain routinised patterns exist. The results suggest that people (mostly the fulltime workers) develop stable travel patterns during the workdays, but during the weekends, they look for variety and leisure opportunities and consequently have a more variability in their travel pattern.
