Measuring Workplace Travel Behaviour: Validity and Reliability of Survey Questions

Table 3

Mean survey, travel diary, and accelerometer outcomes by travel mode.

Mode	Survey		Travel diary		Accelerometer
	𝑛 (%)	Time (minutes)	𝑛 (%)	Time (minutes)	% MVPA*	MVPA time** (minutes)
Car	37 (82)	43	33 (73)	46	6	2.6
Public transport	3 (7)	67	7 (16)	60	14	8.3
Walked/cycled	5 (11)	25	5 (11)	16	24	3.8

∗% MVPA is the MVPA time for the journey to work from accelerometer data divided by the total time for the journey to work from travel diary.
**MVPA time in minutes for the journey to work calculated for all 65 participants.
