A share taxi (also called shared taxi) is a mode of transport which falls between a taxicab and a bus. These vehicles for hire are typically smaller than buses and usually take passengers on a fixed or semi-fixed route without timetables, but instead departing when all seats are filled. They may stop anywhere to pick up or drop off their passengers. Often found in developing countries, the vehicles used as share taxis range from four-seat cars to minibuses. They are often owner-operated.
The UITP term "informal transport" includes share taxis.
A given share taxi route may start and finish in fixed central locations, and landmarks may serve as route names or route termini. In some African cities routes are run between formal termini, where the majority of passengers board. In these places the share taxis wait for a full load of passengers prior to departing, and off-peak wait times may be in excess of an hour.
In other places there may be no formal termini, with taxis simply congregating at a central location, instead.
Even more-formal terminals may be little more than parking lots.
In South Africa, its also referred to as a rank, which denotes an area specifically built, by a municipality or city, for taxi operators, where commuters may start and end their journey.
Where they exist, share taxis provide service on set routes within and sometimes between towns.
After a share taxi has picked up passengers at its terminus, it proceeds along a semi-fixed route where the driver may determine the actual route within an area according to traffic condition. Drivers will stop anywhere to allow riders to disembark, and may sometimes do the same when prospective passengers want to ride.
While all share taxis share certain characteristics—and many regional versions exhibit peculiarities—some basic operational distinctions can be delineated.
Most share taxis are operated under one of two regimes. Some share taxis are operated by a company. For example, in Dakar there are company-owned fleets of hundred of car rapides. In Soviet Union, share taxis, known as marshrutka, were operated by state-owned taxi parks. There are also individual operators in many countries. In Africa, while there are company share taxis, individual owners are more common. Rarely owning more than two vehicles at a time, they will rent out a minibus to operators, who pay fuel and other running costs, and keep revenue.
