Mode of transport (or means of transport or transport mode or transport modality or form of transport) is a general term for the different kinds of transport facilities that are often used to transport people or cargo.
Where more than one mode of transport is used for a journey, or for transport analysis, the journey can be described as multi-modal.
Worldwide, the most widely used modes for passenger transport are the Automobile (16,000 bn passenger km), followed by Buses (7,000), Air (2,800), Railways (1,900), and Urban Rail (250) [1].
The most widely used modes for freight transport are Sea (40,000 bn ton km), followed by Road (7,000), Railways (6,500), Oil pipelines (2,000) and Inland Navigation (1,500) [2].
