Transport or transportation is the movement of people and goods from one location to another. Transport is performed by various modes, such as air, rail, road and water.

The field can be divided into infrastructure, vehicles, and operations. Infrastructure consists of the fixed installations necessary for transport, and may be roads, railways, airways, waterways, canals and pipelines or terminals such as airports, railway stations, bus stations and seaports. Vehicles traveling on the network include automobiles, bicycles, buses, trains, people and aircraft. Operations deal with the way the vehicles are operated, and the procedures set for this purpose including the financing, legalities and policies. In the transport industry, operations, and ownership of infrastructure, are both public and private, depending on the country and mode.

Passenger transport may be public or private. Freight transport has become focused on containerization, while bulk transport is used for large volumes or durable items. Transport plays an important part in economic growth and globalization, but has a deteriorizing impact on the environment. While it is heavily subsidized by governments, good planning of transport is essential to make traffic flow, and restrain urban sprawl.
