Thank you for visiting this survey page, your participation will help us a lot, and if you leave your email address we'll send you our final report when we're finished (see our privacy statement). This study is being conducted as part of the Civil Engineering 256 Sustainable Transportation course at UC Berkeley. The survey should take less than 5 minutes. There are four sections and 18 short questions. All responses (including your name and email address) are optional but the more carefully you complete this survey the more it will help us in our coursework. Thanks again!
