The TPG, Geneva's public transport operator, operates secondary bus lines within the municipality. The main one is line 72, which connects the hamlets of Bourdigny, Choully, and Peissy to Satigny-village and its train station. Another important line is the number 73 which connects Satigny-village to Peney, the industrial area of Bois-de-Bay, the small industrial area of La Tuillière, Vernier and the ZIMEYSA. Finally, two more lines, the 70 and 71, connect the town to two tram lines, in Meyrin (71) and Bernex (70), the latter via Aire-la-Ville (that town's only means of public transport).
