TimeUse+ Pretest: Restricted data

Abstract

The TimeUse+ study is an effort to collect data to understand daily patterns in travel, time use, and expenditure behavior. Study participation begins with an initial survey that collects personal and household level characteristics along with information on mobility tool ownership. Next, participants took part in either 14 or 28 days of tracking and validating, or annotating, their passively recorded events with all of the activities their performed at each location or during travel. For each activity, some or all of the following attributes had to be validated: duration, social partners, and expenditures. The TimeUse+ smartphone app was developed specifically for this project and the tracking portion relies on the software development kit from MotionTag (www.motiontag.com). After a successful tracking period, participants completed a final questionnaire that mainly collected long-term expenditure information. 7,500 individuals were invited to participated in this pretest between March and April 2022, and 205 successfully completed all three parts (i.e. net response rate around 2.7%).
