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 2017-18 survey was administered online in October and November 2017, distributed by email to a stratified random sample of 19,796 students, faculty, and staff (out of an estimated total population of 47,450). Over 20 percent (4,059 individuals) of those contacted responded to this year’s survey, with 18.9 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.

For this STARS report, we elected to use the 2017-18 survey because this report feeds our greenhouse gas inventory. We are reporting 2018 GHG inventory data, because as of March 6, 2020 we are in process with constructing our 2019 GHG inventory.


Has the institution gathered data about employee commuting behavior?:
Yes

Total percentage of employees that use more sustainable commuting options as their primary mode of transportation:
