Transportation was the movement of people, animals, cargo, or other objects from one location to another. Methods of transportation included walking/running, using vehicles, riding animals, or some other transportation device. Transportation often occurred on land with land-based vehicles, through the air with aircraft, underground via tunnels, on and under water with watercraft, and in space with spacecraft. Infrastructure which made for easier transportation included roads, rails, waterways, canals, train stations, and public transportation systems.
In 2364, Data explained to Worf that an automobile was an ancient Earth device used primarily for transportation. (TNG: "The Big Goodbye")
