Dear <FIRSTNAME>: Thank you for your help in the first phase of the Cobb County Driver Satisfaction Study! This study is the first of its kind to be conducted in the United States. The information you have provided will play an essential role in our understanding of which roadway attributes of <ROAD> are most important to you. Our ultimate goal is to work with transportation planners to incorporate driver satisfaction into the road design of the future. We will be contacting you shortly for the final phase of the study and asking you to repeat the drive. This phase, which is scheduled for late-March through mid-May, will give us a second set of measures for a different season and will improve the overall quality of the study. As in the first part of the study, we will call you to schedule your drive and send you survey forms that you will complete and return immediately following your drive. In the meantime, we ask your help with the following: Confirm your contact information: We have listed your contact information (including phone and email) at the top of this letter. If your information has changed or you anticipate it changing before April, please correct the information listed and either fax the updates to Stacey at 1-800-626-9294 (toll-free fax line) or go to the project website and update your information directly using your driver id <DRIVERID> http://surveys.nustats.com:8080/volpe/ Let us know if you have questions or feedback: Because we cannot conduct this study without your help, we have also opened a comment form on the project website if you would like to give us feedback on the survey process or have questions about the spring survey effort. If you do not have internet access, you can also call Stacey Bricka at 1-800-447-8287, ext 2240 or fax her your comments at 1-800-626-9294. Your continued participation is vital to the success of the study. We appreciate the time and effort that you have put into the survey, and are including a small token of appreciation for your time. We look forward to talking with you in a few months, but if you have questions or comments in the meantime, please feel free to contact me at 617-494-3692 or jane.lappin@volpe.dot.gov. Sincerely, Jane Lappin Program Manager
