Our Missions

Île-de-France Mobilités designs, organizes and finances transport for everyone living in the Ile-de-France region.

Every day in Île-de-France 9.4 million trips are made by residents using one of the largest public transport networks in the world. Whether for business or pleasure, with a Navigo pass (card or smartphone) or a single ticket, passengers can ride on the 1,500 bus routes, 14 metro lines, 9 tram lines and 13 train and RER lines which crisscross the Region. In the next ten years or so, the Île-de-France Mobilités network will have been enhanced with numerous extensions and new metro, tram and RER lines under construction at the moment, including the future lines 15, 16, 17 and 18 and the regional metro (Grand Paris Express project).

To operate all of these lines every day, Île-de-France Mobilités has contracts with transport companies such as RATP, SNCF, Transdev, Keolis, RATP Dev, Savac-Lacroix and many others.

The cost of running this gigantic system amounts to more than 10.5 billion euros each year. It is financed by local authorities (region, departments and the City of Paris), employers via a transport subsidy tax and the obligation to cover 50% of the cost of transport for staff, and by the ticket sales. It’s Île-de-France Mobilités that creates the various ticket types such as Ticket t+, Navigo Liberté+, Navigo weekly/monthly/annual passes, Imagine’R pass, Senior pass and Junior pass, and sets the prices.

Ile-de-France residents’ needs in terms of transport and mobility are constantly evolving. It is the local elected representatives who sit on the Île-de-France Mobilités board of directors who make all the major decisions that allow us to anticipate, adapt and modernise the transport service in line with passengers’ needs.

In this way, Île-de-France Mobilités oversees all of the major transport modernisation programmes such as the renewal of trains, making stations accessible, replacing diesel buses with clean buses and so on. It decides on the extensions and new tram, RER, metro, bus and even cable car lines!

These long-term projects are carried out after an evaluation of their technical feasibility, their cost and their interest for passengers to save time or improve connections for example. There are also numerous discussions with the population, elected officials and the municipalities concerned, in order to best respond to local challenges.

With a proactive policy to promote the development of the use of bicycles or carpooling, but also by offering passengers increasingly efficient and multimodal route planning tools, Île-de-France Mobilités is committed to promoting the most environmentally friendly travel solutions, helping improve the region’s air quality and, as a result, the health of Ile-de-France residents.
