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.
- 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. - Sends helpful nudges
You’ll get short, encouraging messages that make it easier to try out healthier, low-emission modes of travel. - Shows Your Impact
Track the emissions you’ve avoided, calories burned, and trips completed—and earn digital badges along the way! - Keeps Your Data Safe
All data is securely stored, anonymized, and used solely for research to help improve local transportation systems.
