A brief description of the method(s) used to gather data about employee commuting, including the timeframe for when the analysis was conducted and how a representative sample was reached, if applicable:

The 2015 Transportation survey was conducted primarily online, but was also distributed in paper form to employees who do not have regular internet access at work, to gather information on how staff, faculty, and graduate students commuted to campus the week of October 26, 2015. 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 employees, a representative percentage of each category was surveyed (Managerial & Professional, Clerical & Technical, and Service & Maintenance).


The percentage of the institution's employees that use each of the following modes as their primary means of transportation to and from campus::
Percentage (0-100)
Commute with only the driver in the vehicle (excluding motorcycles and scooters) 54.28
Walk, bicycle, or use other non-motorized means 17.40
Vanpool or carpool 5.34
Take a campus shuttle or public transportation 20.47
Use a motorcycle, scooter or moped 0.66
Telecommute for 50 percent or more of their regular work hours 1.82

Additional documentation to support the submission:

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.
