A brief description of the method(s) used to gather data about student commuting:

The biennial Transportation Survey was conducted in 2019 to gather information on how staff, faculty, and graduate students commuted to campus the week of October 21, 2019. The survey was conducted primarily online, but was also distributed in paper form to employees who do not have regular internet access at work. The survey used a stratified random-sample methodology that followed guidance developed by the U.S. Environmental Protection Agency for evaluating commuter benefit programs pursuant to air quality regulatory requirements for states. For graduate students, a representative percentage of students from the Graduate School of Arts & Sciences and twelve professional schools was surveyed. Undergraduate students are not included in the survey, as less than 2% of the population drives to campus.

A campus-wide transportation survey was first created and distributed in 2007 to provide Yale University with an accurate baseline assessment of its transportation and parking initiatives and how the university population commutes to and from campus. Now conducted biennially, the results from these surveys constitute a baseline for the University to measure progress against itself and compare to other similar institutions. In addition, the data lends support for implementing programs and initiatives that will help increase the use of more sustainable modes of transportation, rather than driving alone, and provide direction for new transportation initiatives.
