The European Agreement on Main International Traffic Routes is a treaty aimed at improving road transport across Europe. It establishes a network of key routes that facilitate international traffic, enhancing connectivity between countries. The agreement promotes the development and maintenance of these routes to ensure safe and efficient transportation. Signed in 1975 under the auspices of the United Nations Economic Commission for Europe (UNECE), the agreement includes provisions for the classification and improvement of roads. It serves as a framework for cooperation among member states, encouraging investments in infrastructure and harmonizing traffic regulations across borders.
