Current projects
Annual Research-to-Practice Transit Symposium
A yearly event where transit researchers and practitioners share insights on using research to improve transit planning.
A Machine Learning Framework for Travel Mode Classification from Sparse GPS Data
The team built a computer model that learns from a small set of labeled GPS trips and then predicts whether new, sparsely recorded trips are walking, driving, or bus rides, helping planners see travel patterns without dense data collection.
