Airport transport includes a variety of transportation options, such as cabs, trams, and minibuses. Cabs, which are also known as taxis, are typically small vehicles that can be hailed on the street or called for pick-up. Trams are larger vehicles that run on tracks and are usually used in urban areas. Minibuses are larger than cabs and smaller than trams, and are often used to transport groups of people. All three of these forms of transportation are commonly used at airports to get passengers to their destinations.
