Carpooling (also known as car-sharing, ride-sharing, lift-sharing and vanpooling), is the shared use of a car by the driver and one or more passengers, usually for commuting. Carpooling involves varying degrees of formality and regularity and makes use of private cars, or a jointly hired vehicle, for private shared journeys. Carpooling reduces the costs involved in driving by sharing cars, sharing rental charges, or paying the main car owner. In many cases, companies or local authorities encourage carpooling through the provision of central listing facilities, defined pick-up points, preferential parking and general advice. Private rideshare agencies may also provide services to enable one-off or regular carpooling in defined areas. In the "dynamic ridesharing" concept, a separate system performs a carpool match automatically through the Internet, mobile phones and other software systems.
