A taxicab, also non 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. This differs from other modes of public transport where 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:
Hackney carriages, also non as public hire, hailed or street taxis, licensed for hailing throughout communities
Private hire vehicles, also known as minicabs or private hire taxis, licensed for pre-booking only
Taxibuses, also come many variations throughout the developing countries as jitneys or jeepney, operating on pre-set routes typified by multiple stops and multiple independent passengers
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. Disputes over whether smartphone-based ride hailing services should be regulated as taxicabs has resulted in some jurisdictions creating a new classification called transportation network company.
