A brief description of the method(s) used to gather data about student commuting:
The UC Davis Campus Travel Survey is a joint effort by the Transportation & Parking Services (TAPS) and the Sustainable Transportation Center, part of the Institute of Transportation Studies at UC Davis. Since 2007 the survey has been administered each fall by a graduate student at the Institute of Transportation Studies. The main purpose of the survey is to collect annual data on how the UC Davis community travels to campus, including mode choice, vehicle occupancy, distances traveled, and carbon emissions. The annual travel survey results have been used to assess awareness and utilization of campus transportation services and estimate demand for new services designed to promote sustainable commuting at UC Davis. Data from the campus travel survey have also provided researchers with valuable insights about the effects of attitudes and perceptions of mobility options on commute mode choice.
The 2021-22 survey was administered online in October and November 2022, distributed by email to a stratified random sample of 20,169 students, faculty, and staff (out of an estimated total population of 49,159). Over 21 percent (4,265 individuals) of those contacted responded to this year’s survey, with 20.7 percent actually completing it.
For the statistics presented throughout this report, the responses are weighted by role (freshman, sophomore, junior, senior, Master’s student, PhD student, faculty, and staff) and gender, so that the proportion of respondents in each group reflects their proportion in the campus population.
We generally use the survey responses for the previous year to report commuting share because the academic year generally has a larger overlap with the reporting year. For this STARS report, we elected to use the 2021-22 survey because survey responses in 2020 were significantly impacted by the COVID-19 Pandemic.
