A Smartphone Solution for Collecting and Processing Travel Behavior Data

Daynamica™ is an innovative smartphone application that collects and processes highly detailed activity and travel behavior data with minimal user burden. The open-source app is a compelling alternative to the traditional diary-based method typically used to collect individual travel and activity information. It delivers richer, more accurate data—more efficiently, and at lower cost.

Daynamica automatically captures and classifies detailed travel behavior data about multiple travel modes.
