History

Taximeters existed in ancient Rome, where they employed a mechanism that used the turning of the cart’s axle to release small balls. At the end of the trip, the passenger paid based on the number of released balls. The modern taximeter was invented by German Wilhelm Bruhn in 1891, and the Daimler Victoria—the world’s first meter-equipped (and gasoline-powered) taxicab—was built by Gottlieb Daimler in 1897.

Taximeters were originally mechanical and mounted outside the cab, above the driver’s side front wheel. Meters were soon relocated inside the taxi, and in the 1980s electronic meters were introduced, doing away with the once-familiar ticking sound of the meter’s timing mechanism.

In some locations, taxicabs display a small illuminated sign indicating if they are vacant. In Argentina, this sign is called a "banderita" (little flag), a carryover term from the days of mechanical taximeters, in which a little flag was turned to wind up the mechanism. The flag would be hidden at the start of a trip and moved to the visible position at the end.

Horse-drawn for-hire hackney carriage services began operating in both Paris and London in the early 17th century. The first documented service was started by Nicolas Sauvage in Paris in 1640. His vehicles were known as fiacres, as the main vehicle depot apparently was opposite a shrine to Saint Fiacre. (The term fiacre is still used in French to describe a horse-drawn vehicle for hire, while the German term Fiaker is used, especially in Austria, to refer to the same thing). In London the Hackney Carriage Act (1635) became the first legislated control in English on vehicles for hire. In the 19th century, Hansom cabs largely replaced the older designs because of their improved speed and safety.

The first taxi service in Toronto, "The City", was established in 1837 by Thornton Blackburn, an ex-slave whose escape from Detroit was the impetus for the Blackburn Riot.

Although battery-powered vehicles enjoyed a brief success in Paris, London, and New York in the 1890s, the 1891 invention by German Wilhelm Bruhn of the taximeter (the familiar mechanical and now often electronic device that calculates the fare in most taxicabs) ushered in the modern taxi. The first modern meter-equipped taxicab was the Daimler Victoria, built by Gottlieb Daimler in 1897. The first modern taxi company was opened by Friedrich Greiner and began operating in Stuttgart the same year.

Gasoline-powered taxicabs began operating in Paris in 1899, in London in 1903, and in New York in 1907. The New York taxicabs were imported from France by Harry N. Allen. Allen was the first person to paint his taxicabs yellow, after learning that yellow is the colour most easily seen from a distance.

Taxicabs proliferated around the world in the early 20th century. The first major innovation after the invention of the taximeter occurred in the late 1940s, when two-way radios first appeared in taxicabs. Radios enabled taxicabs and dispatch offices to communicate and serve customers more efficiently than previous methods, such as using callboxes. The next major innovation occurred in the 1980s, when computer assisted dispatching was first introduced.

There has generally been a legal struggle concerning the certification of motor vehicles to be taxicabs, which take much more wear than a private car does. In London, they were additionally required to meet stringent specifications (Metropolitan Conditions of Fitness - MCF), adopted in entirety by a number of other large UK cities (including Glasgow and Edinburgh), for example, as concerns turn radius, which resulted for a time in having only one make legally usable. In the US, in the 1930s, the cabs were often DeSotos or Packards. General Motors offered a specialized vehicle for a time, named the General. The firm Checker came into existence then, and stopped manufacturing cabs in the early 1980s. Its cars were specially built to carry "double dates." But now New York City requires that all taxicabs be ordinary cars. They are mainly long-wheelbase versions of the Ford Crown Victoria. Toyota Sienna minivans are the alternate vehicle of choice in New York’s cab fleet. In the 1960s in Europe, Mercedes-Benz and Peugeot offered diesel taxicabs. This form of engine is now the norm in Europe due to its superior fuel economy, torque and reliability.

In recent years, some companies have been adding specially modified vehicles capable of transporting wheelchair-using passengers to their fleets. Such taxicabs are variously called accessible taxis, wheelchair- or wheelchair-accessible taxicabs, modified taxicabs, and so on.

• Mexico City’s ubiquitous VW Type 1 (Beetle) cabs were green and white (being firstly yellow) by law until early 2003. However, the tiny cars had been displaced by bigger four-door sedans, the Nissan Tsuru, a Sentra MkIII (B13) based saloon and recognized for their red/white (or silver) body color. No VW are colored this way anymore. Matchbox released a scale model of the VW taxi in 2004, numbered 31.

• Brazilian taxis are colored orange in Curitiba, yellow in Rio de Janeiro and white in Sao Paulo.
