Uzbekistan occupies an important geostrategic position in Central Asia, through the territory of which the Great Silk Road, where numerous trade routes converged, was in ancient times, and an intensive process of mutual enrichment of the cultures of the peoples of the world was under way. And today, there are crossroads of transport routes leading from the East to the West, from the South to the North. For us, the task of preserving a place in international transport with the purpose of developing the efficiency of transportation must be urgent.
