The THNS Forum is an International Symposium on the Sustainable Development of Urban Transport Systems. The forum got the name T-H-N-S from the theme of its first edition in 2008- “Transport à Haut Niveau de Service” (transport of high-level service). THNS especially fosters the East-West exchange of knowledge advances: research outcomes, innovative technologies, implementation reports etc. Of primary interest to academics and consultants, it may also be of interest to specialized policy makers and business representatives (operators, constructors).
