Project: MobAgent - Large Language Model Agent for Mobility Reasoning and Synthesis 
Collaborator: Latifa Oukhellou (Université Gustave Eiffel) 
Funder: NSERC ($300,000)
MobAgent will create realistic, high-resolution human mobility data from diverse and sparse sources like transit cards, call records, and social media—sources that current AI methods struggle to integrate, thereby limiting their application in transportation planning and urban management. Leveraging large language models to enhance deep generative models,  MobAgent will produce privacy-preserving data that can capture complex travel patterns. These methods will provide reproducible, adaptable mobility data to support sustainable transportation, equitable urban access, and evidence-based planning, while fostering international France-Canada collaboration.
