How it works

TranSACT is a mobile app designed to make sustainable travel easier, more fun, and more rewarding—for both you and your community.


  1. Tracks your trips
    With your permission, the app uses location data to automatically log trips and detect how you traveled—by foot, bike, bus, or car.
  2. Sends helpful nudges
    You’ll get short, encouraging messages that make it easier to try out healthier, low-emission modes of travel.
  3. Shows Your Impact
    Track the emissions you’ve avoidedcalories burned, and trips completed—and earn digital badges along the way!
  4. Keeps Your Data Safe
    All data is securely stored, anonymized, and used solely for research to help improve local transportation systems.
