Lines 32 and 34 have in common that they connect the municipalities of Chaville, Viroflay and Vélizy-Villacoublay. While line 34 offers a fine network of the city of Vélizy-Villacoublay and service to the Vélizy 2 shopping centre, line 32 continues its route to the south to serve Jouy-en-Josas and the HEC Campus.
As of 22 August 2022, Île-de-France Mobilités is increasing the frequency of lines 32 and 34 on Sundays and public holidays to support the development of their ridership, at a rate of one bus every 45 minutes during the day instead of 60 minutes previously.
These reinforcements represent 9 additional departures on line 32 and 8 additional departures on line 34, every Sunday all year round.
