"A taxicab, also known as a taxi or a cab, is a type of vehicle for hire with a driver, used by a single passenger or small group of passengers often for a non-shared ride. A taxicab conveys passengers between locations of their choice. In modes of public transport, the pick-up and drop-off locations are determined by the service provider, not by the passenger, although demand responsive transport and share taxis provide a hybrid bus/ taxi mode.
There are four distinct forms of taxicab, which can be identified by slightly differing terms in different countries:
(1) Hackney carriages also known as public hire, hailed or street taxis, licensed for hailing throughout communities.
(2) Private hire vehicles, also known as minicabs or private hire taxis, licensed for pre-booking only.
(3) Taxibuses, also known as Jitneys, operating on pre-set routes typified by multiple stops and multiple independent passengers.
(4) Limousines, specialized vehicle licensed for operation by pre-booking.
Although types of vehicles and methods of regulation, hiring, dispatching, and negotiating payment differ significantly from country to country, many common characteristics exist." [Taxicab. Wikipedia]
