Revisiting the impacts of virtual mobility on travel behavior: An exploration of daily travel time expenditures

There has been a growing interest in the association between online activities and daily activity-travel patterns. An analysis of this relationship is even more crucial considering the major disruptions to out-of-home activity participation and travel due to the COVID-19 pandemic. This study contributes to the literature by exploring the relationships between Information and Communication Technology (ICT) use (focusing on telework and online shopping) and time spent traveling using different transportation modes. Using Tobit regression models, we investigate the impacts of ICT use on three travel alternatives: (1) automobile, (2) public transit, and (3) active travel. The results show that the effects of ICT use vary across these three travel modes. For example, all else being equal, respondents with higher durations of telework tend to spend less time on auto and transit. Respondents with higher durations of online shopping spend more time walking and bicycling. This study also explores whether the effects of ICT use on travel durations vary across groups with different socio-demographics and residential location characteristics. For instance, the study finds the greater the level of land-use mixture, the stronger the association between online shopping and time spent bicycling and walking. The research findings can inform planners and decision-makers on the relationships between ICT use and overall travel behavior in order to assess travel demand under different levels of ICT use.

Automated summary

This study examines the relationship between Information and Communication Technology (ICT) use and travel durations by different transportation modes. The results show varying effects of ICT use on time spent on driving, public transit, and active travel. Longer durations of telework reduce time spent on driving and public transit, while longer durations of online shopping increase time spent on walking and biking. The study also investigates how ICT use impacts travel durations across different socio-demographics and residential location characteristics, highlighting the importance of considering these factors in transportation planning.
