City conveyance is a term used to describe the various forms of transportation available in cities. This includes taxis, cabs, and buses. Taxis are four-wheeled vehicles that can be hailed on the street or called for a pick-up. Cabs are similar to taxis, but they are usually smaller and may not have a meter. Buses are large vehicles that run along fixed routes and are used by many people to get around the city. All three forms of city conveyance provide an efficient way to travel within a city.
