An ecosystem and centre of excellence for all sustainable mobility and transport players

Transalley is an international technology park in Valenciennes in the Hauts-de-France region of France which unites businesses, research laboratories, and training institutions to innovate in the mobility and sustainable transport sectors.

Upon the remains of an ancient Gallo-Roman city, businesses and teams draw inspiration to imagine new technologies, develop their R&D processes, and expand their networks, skills, and talents.

On this land steeped with history, Transalley is now a 34-hectare strategic location connected to the Université Polytechnique Hauts-de-France and unites all the players in the Mobility/Transport sector. Close to both research and testing facilities, it is in the heart of one of the most dynamic regions in the automobile, railway, aeronautic, and new mobility solution domains.

Transalley offers an environment that favours business development. The technology park, designated a Parc d'innovation Hauts-de-France, provides equipment and services that meet the highest standards of international science and technology parks. It offers unique amenities including, notably, a testing and demonstration track for intelligent transport systems as well as the Institut des Mobilités et des Transports Durables, a veritable events centre.
