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

The survey was distributed to a significant sample of faculty, staff, and students via email from 9/23/19 to 9/27/19 and received 755 responses.

The Office of Institutional Research and Assessment (OIRA) provided a representative sample of the campus population of faculty, students, and staff. OIRA checks the samples against the population on all of the characteristics included to ensure they are exceedingly close in terms of representativeness.

The assessment was administered by the Office of Sustainability using Qualtrics. An email was sent to the representative sample, and a follow up reminder email was sent several days later to those who hadn't yet completed the survey.

We excluded any students studying abroad or students that live on campus, as the students who live on campus do not commute to campus.


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

Additional documentation to support the submission:

Ride-sharing was listed as an option in the surveys, however the alone rideshare ("Uber/Lyft/Ridesharing App") was not counted as a "more sustainable" option. This option made up 2.49% of the total trips (employee and student) taken to and from campus in the week surveyed.

Bikeshare and Scooter-share were in the same portion of the survey, so trips taken by bikeshare or scooter share (motorized or not) were included in the "Walk, cycle, or other non-motorized mode."

Telecommuting and distance education data was not counted.
