Table 1.

Characteristics of PA bouts (n=97) used for scenario development (3 bouts with incomplete GPS and no travel data were excluded.)

Scenario	Walk1-GPS (n=40)	Walk2-Diary (n=5)	Walk3- Diary (n=3)	Walk4- Diary (n=4)	NonWalk1- ACC (n=3)	NonWalk2- GPS (n=26)	NonWalk3- Diary (n=16)
Accelerometer counts mean range (counts per 30 s epoch)	[663.4, 2464.6]	[881.6, 1802.3]	[805.4, 1832.5]	[735, 1442.6]	[2874.2, 3360.3]	[548.1, 2198.4]	[701.6, 2158]
GPS coverage ratio range	[0.25, 1]	[0, 0.14]	[0, 0]	[0, 0]	[0.05, 0.89]	[0.62, 1]	[0, 0.19]
GPS median speed range (kmh⁻¹)	[2.15, 5.3]	[2.55, 2.55]	[NA, NA]	[NA, NA]	[0.5, 4.64]	[0.1, 3.15]	[NA, NA]
Number of bouts overlapping with travel diary reported:
• Walking trip	23	5	0	1^*	0	3	0
• Bike trip	0	0	0	1^*	0	0	0
• Car trip	6	0	2	1^*	0	2	0
• Transit trip	2	0	1	0	0	0	0
• Other/unknown mode trip	0	0	0	1^*	0	1	0

Bouts in Walk4-Diary overlapped with a trip with a 10-minute tolerance applied around diary-based trips.
