Your agreement to participate and contact information may be viewed by the University of Delaware Institutional Review Board, which is a committee formally designated to approve, monitor, and review biomedical and behavioral research involving humans.
Geo-location data:
The geo-location data collected by the UdelGPS Client smart phone app and the geo-location data collected by the standalone GPS unit is anonymous. The study is designed so that the geo-location data cannot be connected with your contact information.

15. Is the data sent to the University of Delaware anonymous, confidential?
Your contact information is confidential; it will never be shared by the University and will only be used for the purpose of contacting you for this study. The geo-location data is anonymous. The study has been designed so that the contact information and the anonymous cannot be linked to each other.

16. Why are you collecting my geo-location every 30 seconds? Isn’t that overkill?
The 30 second interval is required so that we can attempt to estimate travel speed, and mode of transportation for the anonymous geo-location data.

17. Can I get access to the data I sent to the University of Delaware?
Unfortunately you cannot. We designed the study so that individual data points cannot be any way attributed to contact information. The data that is being collected is anonymous.

18. What type data is being transmitted to the University of Delaware?
Both the UdelGPS Client smart phone app and the standalone GPS unit collect actual geo-location data such as: X,Y coordinate with a precision of about +-5 meters, calculated direction, calculated speed, estimated battery status, time, randomly assigned device ID (cannot be connected to your contact information) and randomly assigned protocol ID for the device (cannot be connected to your contact information).

19. Who has Access to this data?
The contact information and geo-location data is only accessible by the Principal Investigator and 3 other researchers employed at the University of Delaware’s Center for Applied Demography & Survey Research, all trained in Human Subjects data protection.

20. How will the data be reported?
The data is processed in aggregate form. We use quantitative techniques to estimate descriptive characteristics such as mode of transportation, source and destination, speed, trip purpose and demographic characteristics at the Census Tract level from the geo-location data. Only this descriptive, anonymous data will be shared with the Department of Transportation. None of this is connected to your contact information. They will utilize it to determine current and future transportation needs and services by in Delaware.

21. What do I do if I no longer want to participate in the study? How do I unsubscribe from the email reminders?
If you installed the UdelGPS Client smart phone app, uninstall it and respond to the e-mail reminder so that we no longer contact you. If you were sent a standalone GPS unit, send it back to us and respond to the reminder email letting us know that you do not want to participate.
