Did you know? 900,000 people use carpooling every day to get to work.

Good for the wallet, to save time and for the planet, carpooling is one of the preferred mobility solutions for Ile-de-France residents, in addition to public transport.

Since 2017, Île-de-France Mobilités has been investing in the development of carpooling

Encouraging Ile-de-France residents to choose more responsible mobility requires the development of more comfortable and accessible public transport and the transformation of our relationship with the car, by making it, together, more ecological.  

To this end, and to facilitate easier access to public transport for the inhabitants of the Ile-de-France region who are furthest from it, Île-de-France Mobilités is investing in the development of carpooling with, in 2023, 2 million subsidised journeys.

New lines dedicated to carpooling and a dedicated application

From 2025, lines dedicated to carpooling will allow Ile-de-France residents, particularly in the Greater Suburbs, to easily reach their workplace, public transport or major train stations in the area.

What is a carpooling line?

Car trips, bookable on an app, to be shared with other Ile-de-France residents on predefined routes and connected to the Île-de-France public transport network.

One app to book all your rides

To book their trips, Ile-de-France residents have an application in the colours of Île-de-France Mobilités "Lignes de covoiturage IDFM"available for download on iOS and Android from 28 April 2025.
