After 3 long years and 2 missed editions, the MobiLab team again massively participated to the Transportation Research Board Annual Meeting. Piergiorgio and Federico presented their posters. It was also the first experience in DC for Haruko, Nicola and Juan, and Claudia joined them after a nice 4-months experience at the University of Montreal. Many sessions and receptions attended, new friends and contacts, all team members returned with acquired knowledge and inspiration. TRB is always a rewarding experience!
