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

The Tufts Operations Division and Office of Sustainability administered an online commuting survey to staff and faculty on the university’s three campuses between April 22 and May 23, 2014. The "simple random sample survey method" was used to obtain a representative cross-section of the employee population on each campus. A total of 1,974 non-students completed the survey, including staff, faculty, post-docs, and others who didn't fit nicely into a student, faculty or staff category. This represents 32% of employees, of which 1,878 completed the question related to commute method for the week of April 7-11, 2014.

In the survey, employees were asked how they commuted from home to Tufts during the period of Monday, April 7 to Friday, April 11, 2014. Those who traveled by multiple modes of transportation (e.g., walk to the subway station) were asked to choose the mode with the most miles traveled.

To obtain the numbers above, the totals for all 5 days of the week for each mode of transportation were averaged (e.g., 108 employees biked to campus on Monday, 102 on Tuesday, 108 on Wednesday, 106 on Thursday, and 94 on Friday - these numbers were averaged to give a total of 103.6 employees commuting by bike). The total number of respondents (1,878) was used as the denominator to calculate the above percentages.

Note in particular that the percentage for telecommuting provided above was calculated in the same manner and reflects the average number of people who telecommuted to the university during that week. It does not include people who telecommuted for part of a day.

Employees completing the survey could select one of the following commuting modes: Drive Alone, Carpool, Vanpool, Motorcycle/Scooter/Moped, MBTA Bus, Tufts Davis Square Shuttle, Subway (the T), Commuter Rail/Regional Train, Bicycle, Walk, Telecommute, Flextime/Day off, Other, and Not at Tufts. Flextime, Other, and Not at Tufts constituted the remaining 10.9% of respondents.

The weather during the week was as follows (from wunderground.com):
Monday: mean temp 49 degrees F, precipitation 0.04"
Tuesday: mean temp 54 degrees F, precipitation 0.67"
Wednesday: mean temp 50 degrees F, precipitation 0.00"
Thursday: mean temp 47 degrees F, precipitation 0.00"
Friday: mean temp 59 degrees F, trace of precipitation
