Taxicabs in Wikipedia
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. 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.
Taximeters in Wikipedia
Taximeters can include several accessories, or act as components in larger dispatching/control systems. Features include:
Fraud control and prevention (on the part of the owner or operator), through the impression of control tickets or computer monitoring. Additionally, taximeters are often visually sealed by a municipal weights and scales authority after initial calibration.
Radio communication, allowing trip status to be monitored by a dispatcher or supervisor.
Dispatching of trip assignments through radio or data systems.
Interaction with GPS systems to assist with dispatching and to provide security.
Seat sensors that detect the presence of a passenger (to prevent a cab from carrying fares without activating the taximeter).
Credit or prepaid card support.
Passenger transport - taxi why?
Although most people taxis can seem quite expensive and not very cost-effective means of transport, but sometimes there is no other choice. In many places public transport simply does not go, and if you do not know the area, after which we move may be an additional difficulty. Therefore it is worth to take a taxi, especially when traveling in some people. There are in fact special, larger cab, which allows passage of a greater number of people. I must admit that this solution is cost effective, because after splitting the cost of travel, for example, seven or eight people quickly notice that the cost per person is not as great as it might seem. No wonder that the taxis are very popular means of transport.
