This data paper introduces the TimeUse+ data set and outlines the comprehensive survey methodologies employed in its collection. The TimeUse+ study comprised two online questionnaires and a smartphone-based diary, recording travel, time use, and expenditure data. Participants were instructed to utilize the TimeUse+ application over a 4-week period. The app passively tracked participants’ movements via GPS and enabled them to annotate their trips and time spent at fixed locations with relevant time use and expenditure information. We begin by providing an overview of extant research on smartphone-based activity-travel diaries and the survey methodological research that informed the TimeUse+ app’s design. We then delineate the study design and components of TimeUse+, highlighting insights derived from prior focus groups and pretests. The data analyzed in this study were collected during the main study wave of TimeUse+, conducted in German-speaking Switzerland from July 2022 to February 2023. Approximately 63,000 individuals were invited to participate, of which approximately 10% initially indicated interest. Despite the study’s extensive and burdensome nature, we observed a net response rate of 2.1%. We present findings related to travel behavior, time use patterns, and expenditure habits, and discuss the challenges faced and lessons learned during each stage of development and execution of the TimeUse+ study. These extensive longitudinal data, which include validated information on travel mode and purpose, as well as detailed data on duration, social partners, and expenditures associated with activities performed at each destination, are being made available for further research.

本数据论文介绍了 TimeUse+ 数据集，并概述了其收集中采用的综合调查方法。 TimeUse+ 研究包括两份在线调查问卷和一份基于智能手机的日记，记录旅行、时间使用和支出数据。参与者被要求在 4 周内使用 TimeUse+ 应用程序。该应用程序通过 GPS 被动跟踪参与者的活动，使他们能够通过相关的时间使用和支出信息来注释他们的行程和在固定地点花费的时间。我们首先概述基于智能手机的活动旅行日记的现有研究以及为 TimeUse+ 应用程序的设计提供信息的调查方法研究。然后，我们描述了 TimeUse+ 的研究设计和组成部分，强调了从之前的焦点小组和预测试中得出的见解。本研究分析的数据是在 2022 年 7 月至 2023 年 2 月在瑞士德语区进行的 TimeUse+ 主要研究浪潮期间收集的。约 63,000 人受邀参与，其中约 10% 最初表示有兴趣。尽管该研究范围广泛且繁琐，但我们观察到的净响应率为 2.1%。我们提出了与出行行为、时间使用模式和支出习惯相关的研究结果，并讨论了 TimeUse+ 研究的每个开发和执行阶段所面临的挑战和吸取的经验教训。这些广泛的纵向数据包括有关旅行模式和目的的经过验证的信息，以及有关持续时间、社会伙伴以及与每个目的地进行的活动相关的支出的详细数据，可供进一步研究。
