National Center for Sustainable Transportation

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. Over the past seven years, the 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. This year’s survey is the eighth administration of the campus travel survey. The 2014-15 survey was administered online in October 2014, distributed by email to a stratified random sample of 30,815 students, faculty, and staff (out of an estimated total population of 42,405). About 14 percent (4,224 individuals) of those contacted responded to this year’s survey, with 11.4 percent actually completing it. For the statistics presented throughout this report, the authors weighed the responses 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.
