The Transportation SWATeam made the following recommendation: 

"The Transportation SWATeam kindly requests the creation of a survey which would question faculty and staff who travel out of town for conferences or other university-sponsored activities on their decided mode of transportation. This survey would be voluntary and facilitated by the Transportation SWATeam. An example of a question would be something like: 'In the past year, what has been the main reason for the travel you selected?'"
