The Forum T-H-N-S got her name from the theme of the first edition in 2008- “Transport à Haut Niveau Service” (transport of high-level service). THNS is an International Symposium on the Sustainable Development of Urban Transport Systems, jointly initiated in 2008 by Tongji University, ParisTech and the French Ministry for the Environment. During the past years, it has been supported by the Chinese Ministry of Housing, Urban Planning and Rural Construction, the Chinese Ministry of Transportation, the French Ministry for the Ecological and Solidary Transitions and many other Chinese, French and international institutions in the relevant fields.
