About this app

Purpose of this App:
The main purpose of ATLAS II is to examine a methodology for performing Travel Surveys using GPS-enabled smartphones. With installing this application on your smartphone, you will help us to improve the quality of "travel surveys", which provides researchers and practitioners with the detailed travel behaviour data required for more accurate transportation planning and management.

Participation and withdrawal:
Installing this app and participation in travel surveys are completely voluntary, and you are free to withdraw from the study at any time without prejudice or penalty. If you wish to withdraw, simply stop completing the exercise and uninstall the app. If you do withdraw from the study, only the materials that you have uploaded to that point will be included in the study. You have the option to delete any day of your trips before uploading it to the ATLAS II server. You always have the option to delete your travel records or to keep them for your own purpose only.

What this application does:
ATLAS II records the travel behaviour of participants using the GPS tracking facilities on the device. The travel route for a given trip is recorded by storing the positions visited and the corresponding time. Collected data are recorded on the device and only when a participant clicks the upload button, these data are sent to a server. ATLAS II is designed to work in the background and does not interfere with other applications on your smartphone.

As a study participant, you will not be involved in any physical or mental discomfort and no risks beyond those of everyday living. However, if you find any question or procedure to be invasive or offensive, simply stop completing the exercises and uninstall the app.

Confidentiality and security of data:
All collected data in this exercise are encoded to protect those details that might be considered as confidential. Moreover, all recorded travel attributes are de-identified and stored confidentially in a separate database. Only the members of the research team have access to these data.

Please note that continued use of GPS running in the background can dramatically use your smartphone's power.
