Anyone with a smartphone can take pictures anytime anywhere. This opens the opportunity for researchers to collect photos to augment traditional Web survey data. We conducted an experimental survey asking 2700 members of the Dutch LISS panel about …
Passively-generated location data have the potential to augment mobility and transportation research, as demonstrated by a decade of research. A common trait of these data is a high proportion of missingness. Naïve handling, including list-wise …
Currently, travel surveys are the standard method for measuring mobility in official statistics. Nonresponse and measurement are problematic in travel surveys, due to the high burden and non-centrality of the requested information. To overcome these …
This study investigates how an auto-forward design, where respondents navigate through a web survey automatically, affects response times and navigation behavior in a long mixed- device web survey. We embedded an experiment in a health survey …
Smartphone sensors allow measurement of phenomena that are difficult or impossible to capture via self-report (e.g., geographical movement, physical activity). Sensors can reduce respondent burden by eliminating survey questions and improve …
Advances in smartphone technology have allowed for individuals to have access to nearcontinuous location tracking at a very precise level. As the backbone of mobility research, the Travel Diary Study, has continued to offer decreasing response rates …
Invitation letters to web surveys often contain information on how long it will take to complete a web survey. When the stated length in an invitation of a survey is short, it could help to convince respondents to participate in the survey. When it …
The growing smartphone penetration and the integration of smartphones into people’s everyday practices offer researchers opportunities to augment survey measurement with smartphone-sensor measurement or to replace self-reports. Potential benefits …
In this paper we discuss the implications of using mobile devices for online survey completion. With more and more people accessing online surveys on mobile devices, online surveys need to be redesigned in order to be able to meet the characteristics …
Goal: Showing the feasibility of automatic travel mode prediction using smartphone location data in a national travel survey. Data collection: In the fall of 2018, 1,902 respondents were randomly sampled from the Dutch population to participate in a …
