From Wikipedia, the free encyclopedia
Transport is the movement of people, goods, signals and information from one place to another. The term is derived from the Latin trans ("across") and portare ("to carry"). The field of transport has several aspects: loosely they can be divided into a triad of infrastructure, vehicles, and operations. Infrastructure includes the transport networks (roads, railways, airways, canals, pipelines, etc.) that are used, as well as the nodes or terminals (such as airports, railway stations, bus stations and seaports). The vehicles generally ride on the networks, such as automobiles, bicycles, buses, trains, or airplanes. The operations deal with the control of the system, such as traffic signals and ramp meters, railroad switches, air traffic control, etc, as well as policies, such as how to finance the system (for example, the use of tolls or gasoline taxes). Modes of transport are combinations of networks, vehicles, and operations, and include walking, roads, railways, shipping and modern aviation.
