How to Participate

Updated 4/2018: Our study is now closed! We no longer accept new participants.

Very easy! All you need is an Android smartphone. Make sure you turn on your GPS.

The survey will include the following steps:

Step 1: 2 minutes

Download and install Daynamica on your Android smartphone.
Turn on your GPS.
Enter your email address to proceed.

Step 2: 8-10 minutes

Answer the entry questionnaire on Qualtrics (embedded in the app). You will be asked to provide your email address one more time on Qualtrics so we can merge your data from the app and Qualtrics.
After you complete the questionnaire, the app will show a short user’s guide on how to use the app for travel tracking.

Step 3: 1-2 minutes/trip, during 7 days

Answer a few brief questions in the app after you finish each trip. Make sure your GPS is still on!
Although you will not receive push notifications for each trip, we encourage you to answer the questions as soon as possible after each trip.

Your information will be kept strictly confidential.

A note for train riders: GPS signal is unavailable underground. If you ride the Metrorail, you may experience abnormal trip patterns on the app: instead of showing one train trips, the app will break it down into multiple short train trip-segments with ACTIVITY/INACC in between (see image). Please answer the trip survey for the first train segment only and ignore the rest of the train segments for that trip.
