TABLE 3.

Physical activities observed in the 60 segments

	Mean^a	SD	Minimum–maximum^b	Total^c
Walking	5.3	4.1	0–19.0	315.0
Bicycling	1.9	1.8	0–8.0	116.0
Jogging	0.7	1.5	0–10.0	42.0

SD = standard deviations

^aMeans and standard deviations (SD) represent the number of individuals observed performing a given physical activity per segment (total observed ÷ 60 segments)

^bMinimum and maximum values represent the minimum and maximum number of individuals observed performing a given physical activity during one 60-min observation of a segment

^cTotal represents the total number of individuals observed during 3,600 min of observation
