Travel Surveys are considered promising candidates to go ‘smart’. Respondents need to be both motivated and competent to correctly report all details of their travels for a specified time period. Location tracking offers options to remove burden and to improve quality of measurement. Adding contextual information, the collected location data may also be input to predictions of travel mode and travel purpose. In order to make daily stop-track segmentations and to link travel modes and stop purposes, location tracking data must be accurate. For this reason, Statistics Netherlands conducted a first field test in 2018 using a proof-of-concept travel app. Location data did show gaps and measurement error, but data were considered sufficiently accurate to justify further development and experimentation.
In 2022, Statistics Netherlands again fielded a travel-app assisted experiment, but this time including the regular online Travel Survey as a concurrent option. The requested tracking period, one full day or one full week, was randomized. And the amount of editing respondents could do on stop-track segmentations was also randomized.
In this paper, we discuss what editing actions respondents performed. The results are the starting point for decisions on what tasks can be expected from respondents.
