Freight transport

Freight transport, also referred as freight forwarding, is the physical process of transporting commodities and merchandise goods and cargo. The term shipping originally referred to transport by sea but in American English, it has been extended to refer to transport by land or air (International English: "carriage") as well. "Logistics", a term borrowed from the military environment, is also used in the same sense. In 2015, 108 trillion tonne-kilometers were transported worldwide (anticipated to grow by 3.4% per year until 2050 (128 Trillion in 2020)): 70% by sea, 18% by road, 9% by rail, 2% by inland waterways and less than 0.25% by air.

Ground transport is typically more affordable than air, but more expensive than sea, especially in developing countries, where inland infrastructure may not be efficient. In air and sea shipments, ground transport is required to take the cargo from its place of origin to the airport or seaport and then to its destination because it is not always possible to establish a production facility near ports due to the limited coastlines of countries. Ship transport and Cargo ship Much freight transport is done by cargo ships. An individual nation's fleet and the people that crew it are referred to as its merchant navy or merchant marine.

On rivers and canals, barges are often used to carry bulk cargo. Cargo airlines Cargo is transported by air in specialized cargo aircraft and in the luggage compartments of passenger aircraft. Air freight is typically the fastest mode for long-distance freight transport, but it is also the most expensive. Multimodal transport Cargo is exchanged between different modes of transportation via transport hubs, also known as transport interchanges or nodes (e.
