On the temporal variation of human activity spaces

摘要: 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 the fact only snapshot such needed capture adequately in survey. problem always define what should period observation which we can see no net change behavior. This paper first discusses various measures activity spaces (Ellipses kernel densities) analyses Mobidrive Uppsala databases three blocks fortnight each (weeks 1 2; weeks 3 4; 5 6). Then were analysed using socio demographic variables studied if certain exist. results suggest people (mostly fulltime workers) develop stable during workdays, but weekends, they look variety leisure opportunities consequently have more variability their pattern.
