| Summary: | With increased internet connectivity, there are more opportunities to substitute physical, or “in-person”, activities with online activities. With this, changes to household and individual travel/activity patterns are to be expected. For example, the increased adoption of e-commerce can affect individual travel destinations and frequency. To study these shifts, we enhance an existing smartphone-based travel/activity diary to capture online activities, with a focus on activities that can replace passenger trips. Furthermore, we expand the options to report shopping details, to better understand the influence of e-commerce on in-person shopping. In this paper, we detail the data collection tool development strategy and user-experience findings. Moreover, we provide insights from a pilot deployment in Singapore during 2020, which allowed measuring travel/activity behavior, expenditure, and time allocation changes during various COVID-19 pandemic travel restriction periods.
