The European Agreement on Main International Traffic Arteries (AGR) is a treaty aimed at improving road transport across Europe. It was established to create a network of main international traffic routes, facilitating the movement of goods and people between countries. The agreement outlines standards for road infrastructure, ensuring that these routes are safe and efficient. Signed in 1975 under the auspices of the United Nations Economic Commission for Europe (UNECE), the AGR includes a list of designated roads and their specifications. This initiative promotes economic cooperation and enhances connectivity among European nations, contributing to regional development and trade.
