Transportation forms the backbone for international trade. Transport breaks down the geographical barriers and provides an avenue for the global flow of commodities, services, and information. Goods are transported by ship, train, truck, lifts, pipelines, and air services. Transport also includes postal transactions, courier services, and third-party logistics.
Transport Network: A pattern formed by a sequence of nodes (nodes) connected by a succession of pathways (links).
Land Transport: The majority of products and services are transported by land.
Human porters, pack animals, carts, and wagons are the most expensive modes of transportation, whereas huge freighters are the least expensive.
