Set up in 2005 by the French Transportation Authorities Association (GART) and the Public and Rail Transport Union (UTP), the purpose of GIE Objectif Transport Public is to promote mass transit and raise the awareness of both industry professionals and the general public regarding issues of sustainable mobility.

This strategy is implemented by organising large-scale events in France. These include:

European Mobility Expo especially for professionals, held every two years in Paris (even-numbered years). The 2024 edition will take place in Strasbourg for the first time.
The National Public Transport Conference including the GART-UTP conferences and exhibition, held every other year (odd-numbered years) in a French region.
National Public Transport Day, held every year in September.
