In 2025, VINCI Autoroutes continued to measure the change in vehicle occupancy rates on motorways around 12 French cities. This eighth solo driving survey found that 84% of drivers still drive alone in their cars in the morning rush hour, down 2.3% on the previous year. However, the vehicle occupancy rate remains below the 2030 target set in France’s National Low-Carbon Strategy – i.e. an average of 1.75 occupants per vehicle—underscoring the need to significantly increase the number of carpoolers. VINCI Autoroutes helps facilitate this shift by adding free carpool parking facilities at the entrances and exits to its network. At end-2025, 68 of these car parks were in service, totalling 5,523 spaces. As part of the motorway investment plan, around 20 additional facilities will be created in the coming years in partnership with regions. VINCI Autoroutes collaborates with local authorities to develop multimodal transport hubs connected to their public transport networks. For example, in Longvilliers, south-west of Paris, express coach services transport A10 users via a special motorway lane to the RER train network, which takes them into the heart of the capital. Another example is the low-carbon motorway agreement signed with the authorities of the greater Tours area (central France), under which seven multi-modal transport hubs are planned along the A10 and A85 motorways in the region.
A consortium led by VINCI Autoroutes continued to develop a project that involves operating smart, autonomous MILLA electric shuttles, with capacity for 12 passengers, on the motorway as part of a trial service provided by SAVAC. The scheme harnesses a robust supervision and intervention system, as well as smart, connected infrastructure able to assist the shuttle buses in passing through tolls and joining the motorway. It supplements the existing express coach service and helps reduce solo driving on the motorway. Launched in September 2025, the trial has already completed more than 1,050 journeys and over 14,000 km autonomously along the route between the Longvilliers multimodal hub and Massy station.
