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 …
Are you interested in surveys, official statistics, apps, and sensors and do you have the ambition to contribute to scientific progress as well as perform socially relevant research? Then a PhD position at the department of Methodology and Statistics of Utrecht University & Statistics Netherlands (CBS) might be just the right job for you.
You will work on a project “Push-to-app: Effective recruitment and retention in smart surveys”. With the increased use of smart devices such as smartphones, wearables, and smart home sensors by individuals, using these devices for data collection is a next logical step for official statistics.
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 …
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 …
