TimeUse+ main study: Data and variable description

Abstract

The TimeUse+ study collected data to understand daily patterns in travel, time use, and expenditure behavior. Study participation began with an initial online questionnaire that collected personal and household level characteristics along with information on mobility tool ownership. Next, participants took part in 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 online questionnaire that mainly collected long-term expenditure information. Just over 63,000 individuals were invited to participate in this study from July 2022 to February 2023, and 1,318 successfully completed all three parts (i.e. net response rate around 2.1%).
