What is a public transport service used in large cities in europe and latin america, but not very common in the united states?

Transport in Europe provides for the movement needs of over 700 million people[1] and associated freight. The political geography of Europe divides the continent into over 50 sovereign states and territories. This fragmentation, along with increased movement of people since the industrial revolution, has led to a high level of cooperation between European countries in developing and maintaining transport networks. Supranational and intergovernmental organisations such as the European Union (EU), Council of Europe and the Organization for Security and Co-operation in Europehave led to the development of international standards and agreements that allow people and freight to cross the borders of Europe, largely with unique levels of freedom and ease.

Road, rail, air and water transportation are all prevalent and important across Europe. Europe was the location of the world's first railways and motorways and is now the location of some of the world's busiest ports and airports. The Schengen Area enables border control-free travel between 26 European countries. Freight transportation has a high level of intermodal compatibility and the European Economic Area allows the free movement of goods across 30 states.

A review of critical success factors for the delivery of transport infrastructure projects in Europe is presented in.
