Going nowhere fast: Might changing activity patterns help explain falling travel?

The inexorable rise in personal travel in the 20th century has given way to stagnation in the 21st, a phenomenon some call "peak travel." We use 2003-2019 data from the American Time Use Survey to explore whether and why personal travel per capita has stopped growing. We show that time spent on personal travel has been dropping consistently over these years, and suggest that one important cause is likely a dramatic and ongoing decline in the time Americans spend on out-of-home activities. We find significant changes in time spent on many of the 34 activities conducted inside and outside of the home that we examine. Many of these changes appear related to advances in information and communications technology (ICT), as this period saw the quality of inhome ICT continually rising and its real cost falling, resulting in ever-improving gaming, surfing, watching, and streaming options. For example, our data suggest that out-of-home work and shopping time fell significantly during our study period, while in-home time spent on work and education rose. Game playing (presumably mostly computer games) and TV watching in the home both increased dramatically, while attendance at live entertainment, arts, and sports activities fell. Reading and writing fell substantially both inside and outside the home, perhaps replaced by electronic communication. Our findings suggest that increased in-home ICT use may have been associated with 25-30% of the reduction of out-of-home time. We also find a significant increase in sleeping, and a decrease in time spent eating and drinking both inside and outside of the home. Although we deliberately chose to examine time use and travel prior to the COVID-19 pandemic, we suspect that, even as the pandemic fades, the trend toward more time at home and less time spent traveling may well increase further.
