Table 1. Relevant data sources with descriptions

Name of the data source	Description
Dutch Mobile Mobility Panel	The survey used in this study. The sample is a sub sample of the LISS panel, which is used for all kinds of panel studies
MoveSmarter trips	The automatically detected and processed trips by the MoveSmarter app and the back end server
Reported trips	The reported trips in the Internet-prompted recall survey in which respondents check and adjust the MoveSmarter trips
One-day trip survey	Self-reported trips on the first day of the experiment during which trips were not detected by MoveSmarter. Used as comparison with the reported trips in the recall survey
Mobility Panel for the Netherlands (MPN)	online and place-based three-day trip diaries of about 4,000 individuals (e.g., Hoogendoorn-Lanser et al., 2014)
Dutch National Travel Survey (NTS)	Pen-paper, one-day trip diaries of over 37,000 individuals (Statistics Netherlands, 2014)

	Success rates per trip length bin	Success rates per travel time bin
0–2 km / 0–7 min	77%	78%
2–7 km / 7–15 min	79%	81%
7–20 km / 15–30 min	87%	85%
20–50 km / 30–60 min	94%	87%
>= 50 km / >= 60 min	95%	83%

Activity (at destination)	MoveSmarter and self-reporting (N trips = 3955*)	One-day trip diary (N trips = 1726)
Work	0.87	0.68
Business	0.26	0.18
Shopping / personal care	0.77	0.68
Education	0.07	0.08
Recreational	0.89	0.62
Touring / walking	0.16	0.23
Bringing / picking up	0.49	0.43
Other	0.27	0.29
Unknown	0.13	0.14
All	3.92 ± 0.09	3,33 ± 0.11

*Based on reports from the two Mondays after the first Monday (used for the one-day trip diary). These comprise 1,008 person-days (slightly less than two days per person, because in some cases a respondent had not approved his or her trips for that day).
