Transportation in Spain is characterized by an extensive network of roads, railways, rapid transit, air routes, and ports. Its geographic location makes it an important link between Europe, Africa, and the New World. Major forms of transit generally radiate from the capital, Madrid, located in the center of the country, to link with the capitals of the autonomous communities. Spanish transit is marked by a high degree of integration between its long distance railway system and inner-city metro systems, although the historic use of broad gauge has limited integration with its neighbors. Spain is currently working to increase and improve linkage with the rail systems of France and Portugal, including high-speed rail between Madrid and Lisbon[1]. Spain possesses a highly developed highway system, with both tolled and freeways. Air traffic is routed through several international and regional airports, the largest of which is Barajas International Airport in Madrid. Ferry services operate regular lines to many ports in Europe and Africa, as well as the autonomous communities and cities of the Balearic Islands, the Canary Islands, Ceuta, and Melilla.
