Since Antiquity, geography has dictated transport routes in Slovenia. Significant mountain ranges, major rivers and proximity to the Danube played roles in the development of the area's transportation corridors. One recent particular advantage are the Pan-European transport corridors V (the fastest link between the North Adriatic, and Central and Eastern Europe) and X (linking Central Europe with the Balkans). This gives it a special position in the European social, economic and cultural integration and restructuring.
