This research has been conducted in partnership with CARB, NCST, SB1, and SCAG.

UC Davis has partnered with SCAG to study the temporary and longer-term impacts of the COVID-19 pandemic on mobility in the SCAG Region. To know more about the SCAG study click here

Fall 2020 survey

The research team launched a new round of data collection in Fall 2020. In this round of online surveys, all respondents from the various versions of the Spring 2020 surveys were invited to participate in a new online survey that will help us investigate the evolution of the impacts on individual mobility as the pandemic entered a new stage in the US and abroad. This data collection will help us understand how a new “normality” in terms of modified travel behavior is emerging, how activity and travel choices evolve during the recovery period, and the resulting impacts on equity and on the environment. 

Summer 2021 Survey

Our research team has launched a new round of data collection in early Summer 2021, following the previous data collections efforts in Spring 2020 and Fall 2020. We are inviting the previous survey respondents, as well as recruiting new participants, to take part in this round of data collection, which is carried out using both online surveys and printed questionnaires, to investigate the evolution of the impacts to individual mobility across various regions in the U.S. The content of the survey covers various topics ranging from work activities, household organization, online shopping, to the use of various travel modes. This new data collection will help us understand how a new “normality” in terms of modified travel behavior is emerging, how activity and travel choices evolve during the pandemic recovery period, and the resulting impacts on equity, the economy, and the environment. 

Spring 2020 Survey

As part of the quantitative component of the project, in Spring 2020, we administered three versions of an online survey to respondents in the United States, Canada, as well as other countries: 

A longitudinal survey (Dataset L) was used to resample respondents from our previous 2018 California mobility survey (~3,400 respondents from California) and 2019 "8 cities" travel survey (~3,300 respondents from Los Angeles, San Francisco, Sacramento, Boston, Seattle, Salt Lake City, Kansas City and Washington DC). This gave us a unique opportunity to build a longitudinal study to investigate the impacts of the pandemic. For all these respondents, the research team had already access to a large dataset containing information on several dimensions of interest, including regular travel patterns, vehicle ownership, household organization, telecommuting patterns, e-shopping behaviors, emerging delivery services, environmental attitudes, land use preferences, use of shared mobility - including ridehailing (e.g. Uber/Lyft), shared ridehailing (i.e. UberPOOL/Lyft Share), car sharing, bike sharing and e-scooter sharing, use of public transit, active modes of transportation, propensity towards AVs, among other variables, from the baseline data collections in 2018 / 2019 (before the COVID-19 pandemic, when everybody was behaving normally). With 1,349 respondents in this version of the COVID-19 survey in 2020, the longitudinal study provides our research team a great opportunity to analyze the changes in individuals’ attitudes and behaviors now as well as when people go back to the “new” normality. 

An Opinion Panel (Dataset O) provides our research team with a breadth of new respondents recruited in 15 regions in the US and two regions in Canada. The 17 study regions include all regions that were already sampled in the longitudinal component of the study (see Dataset L above), with the addition of seven additional US regions and two regions in Canada that were not included in the previous round of data collection. For additional details on the regions included in this part of the study, please see the "Study Regions" page. A total of 8,834 respondents from the 17 regions completed this version of the survey in Spring 2020. 

A Convenience Sample (Dataset C) expanded the data collection with a convenience sample that invited respondents to participate in our study through several different channels, including professional listservs and social media (e.g., Facebook and Instagram ads). The collection of a convenience sample added a relatively simple way to expand the data collection both in the same focus regions described above and in other regions of the US and Canada, as well as in other countries, using the same survey tool that was designed for this study. More than 1,308 respondents completed this version of the survey.
