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. Roads The road freight and passenger transport constitutes the largest part of transport in Slovenia at 80%. Personal cars are much more popular than public road passenger transport, which has significantly declined. Slovenia has a very high highway and motorway density compared to the European Union average. The highway system, the construction of which was accelerated after 1994, has slowly but steadily transformed Slovenia into a large conurbation. Other state roads have been rapidly deteriorating because of neglect and the overall increase in traffic. Railways The existing Slovenian railways are out-of-date and have difficulty competing with the motorway network; partially also as a result of dispersed population settlement. Due to this fact and the projected increase in traffic through the port of Koper, which is primarily by train, a second rail on the Koper-Divača route is in early stages of starting construction. With a lack of financial assets, maintenance and modernisation of the Slovenian railway network have been neglected. Due to the out-of-date infrastructure, the share of the railway freight transport has been in decline in Slovenia. The railway passenger transport has been recovering after a large drop in the 1990s. The Pan-European railway corridors V and X, and several other major European rail lines intersect in Slovenia. Ports The major Slovenian port is the Port of Koper. It is the largest Northern Adriatic port in terms of container transport, with almost 590,000 TEUs annually and lines to all major world ports. It is much closer to destinations east of the Suez than the ports of Northern Europe. In addition, the maritime passenger traffic mostly takes place in Koper. Two smaller ports used for the international passenger transport as well as cargo transport are located in Izola and Piran. Passenger transport mainly takes place with Italy and Croatia. Splošna plovba, the only Slovenian shipping company, transports freight and is active only in foreign ports. Air Air transport in Slovenia is quite low, but has significantly grown since 1991. Of the three international airports in Slovenia, Ljubljana Jože Pučnik Airport in central Slovenia is the busiest, with connections to many major European destinations. The Maribor Edvard Rusjan Airport is
