Transportation is the conveyance of people, animals, or goods from one place to another. Types of transportation include skateboards, bicycles, motorcycles, passenger vehicles, sport utility vehicles, small trucks, large trucks, semi-trucks, buses, forklifts, cranes, tractors, bulldozers, asphalt pavers, backhoe loaders, cold planers, compactors, excavators, harvesters, graders, off-road vehicles, trains, ferries, motorboats, yachts, ships, helicopters, aircraft, battle tanks, infantry fighting vehicles, armored personnel carriers, armored combat support vehicles, mine-protected vehicles, light armored vehicles, light utility vehicles, amphibious vehicles, and more.

This chapter discusses these two WWS solutions.
