A Cross-Scale Representation of Tourist Activity Space

Figures & data

Figure 1. Comparison of overall activity space and localized view of activity space. Although the overall activity space of Tourist 1 and Tourist 2 look similar (left), a localized view reveals the subcomponents in their activity spaces that exhibit different spatial extent and interrelationships (right).

Table 2. The distribution and stay duration of generic itinerary types observed from the 111,645 travelers

Generic itinerary type	No. of travelers	%	Accumulative %	Mean stay duration (days)	Median stay duration (days)
$A$	75,860	67.95	67.95	3.05	2.46
$A –\mathit{ }B$	16,154	14.47	82.42	4.21	3.71
$A –\mathit{ }B –\mathit{ }A$	3,670	3.29	85.70	6.17	5.38
$A –\mathit{ }B –\mathit{ }C$	3,659	3.28	88.98	5.49	4.88
$–$	8,200	7.34	96.33	1.89	1.55
Others (longer sequences)	4,102	3.67	100.00	8.01	7.48
