They are attractive to customers who make only occasional use of a vehicle, as well as others who would like occasional access to a vehicle of a different type than they use day-to-day.

, ad hoc grouping. Today there are more than one thousand cities in the world where people can carshare.

The term "carsharing" is also used for carpooling or ride sharing in some places.

. In the United Kingdom the term "car clubs" is used, while "car sharing" is also used to refer to ride sharing.

The principle of carsharing is simple: individuals gain the benefits of private cars without the costs and responsibilities of ownership. Instead of owning one or more vehicles, a household accesses a fleet of vehicles on an as-needed basis. Carsharing may be thought of as organized short-term car rental.

"Carpooling" or "ride-sharing" refers to the shared use of a car for a specific journey, in particular for commuting to work, often by people who each have a car but travel together to save costs. However, there is a slight terminological hitch in the UK where the term car sharing (two words in this usage) is used for what in the U.S. is called "ride sharing". Carsharing in the sense discussed in this article is a recent development in Britain, and while such plans are still more known as car clubs (a term which, in the U.S., refers strictly to a club of car hobbyists), the international term carsharing is gradually gaining currency there as well.

As is often the case with innovations that spring up more or less spontaneously in different parts of the world, operations are organized in many different ways in different places, according to the objectives of the organizers and users. A small informal start-up may have only one shared car, and only a handful of sharers. Larger services tend to focus on urban areas where there are many potential customers.

Carsharing differs from traditional car rentals in the following ways:
  • Carsharing is not limited by office hours
  • Reservation, pickup, and return is all self-service
  • Vehicles can be rented by the minute, by the hour, as well as by the day
  • Users are members and have been pre-approved to drive (background driving checks have been performed and a payment mechanism has been established)
  • Vehicle locations are distributed throughout the service area, and often located for access by public transport
    Public transport
    Public transport is a shared passenger transportation service which is available for use by the general public, as distinct from modes such as taxicab, car pooling or hired buses which are not shared by strangers without private arrangement.Public transport modes include buses, trolleybuses, trams...

  • Insurance and fuel costs are included in the rates.
  • Vehicles are not serviced (cleaning fueling) after each use, although certain programs such as Car2Go

     continuously clean and fuel their fleet


Some carshare operations (CSOs) cooperate with local car rental firms to offer best value to their customers (in particular in situations where classic rental may be the cheaper option.)

An increasing body of empirical evidence indicates that carsharing can provide numerous transportation, land use, environmental, and social benefits.
Neighborhood carsharing is often promoted as an alternative to owning a car where public transit, walking, and cycling

 can be used most of the time and a car is only necessary for out-of-town trips, moving large items, or special occasions. It can also be an alternative to owning multiple cars for households with more than one driver. A long-term study of City CarShare members by Robert Cervero, Professor of City and Regional Planning at the University of California, Berkeley
University of California, Berkeley

, found that 30 percent of households that joined sold a car; others delayed purchasing one. Transit use, bicycling, and walking also increased among members. A study of driving behavior of members from major carsharing organizations found an average decline in 27% of annual VKT.

Car sharing is generally not cost-effective for commuting to a full-time job on a regular basis. Most carsharing advocates, operators and cooperating public agencies believe that those who do not drive daily or who drive less than 10,000 kilometers (about 6,200 statute miles) annually may find carsharing to be more cost-effective than car ownership. But variations of 50% on this figure are reported by operators and others depending on local context. If occasional use of a shared vehicle costs significantly less than car ownership, this makes automobile use more accessible to low-income households.

Car sharing can also help reduce congestion and pollution. Replacing private automobiles with shared ones directly reduces demand for parking spaces. The fact that only a certain number of cars can be in use at any one time may reduce traffic congestion
Traffic congestion
Traffic congestion is a condition on road networks that occurs as use increases, and is characterized by slower speeds, longer trip times, and increased vehicular queueing. The most common example is the physical use of roads by vehicles. When traffic demand is great enough that the interaction...

Rush hour
A rush hour or peak hour is a part of the day during which traffic congestion on roads and crowding on public transport is at its highest. Normally, this happens twice a day—once in the morning and once in the evening, the times during when the most people commute...

. Even more important for congestion, the strong metering of costs provides a cost incentive to drive less. With owned automobiles many expenses are sunk costs and thus independent of how much the car is driven (such as original purchase, insurance, registration and some maintenance).

Successful carsharing development has tended to be associated mainly with densely populated areas such as city centers and more recently university and other campuses. There are some programs (mostly in Europe) for providing services in lower density and rural areas. Low-density areas are considered more difficult to serve with car sharing because of the lack of alternative modes of transportation and the potentially larger distance that users must travel to reach the cars.

People who have joined car sharing sell either their primary, secondary, or another off-hand car, after using the service. This reduces the cost of transportation per month by an average of $135 – $435, based on University of Berkeley's Research in 2008.

How it works

The technology of CSOs varies enormously, from simple manual systems using key boxes and log books to increasingly complex computer-based systems (e.g. partially automated and fully automated systems) with supporting software packages that handle a growing array of back office functions. The simplest CSOs have only one or two pick-up points, but more advanced systems allow cars to be picked up and dropped off at any available public parking space within a designated operating area.

While differing markedly in their objectives, size, business models, levels of ambition, technology and target markets, these programs do share many features. The more established operations usually require a check of past driving records and a monthly or annual fee in order to become a member. The cost and maximum time a car may be used also varies.

To make a reservation, one can either make a reservation online, by phone, or by text messages depending on the company’s flexibility. Then the company usually asks all the necessary information such as:
  • What time will the car be needed?
  • How long will the car be in use?
  • Where would you like to pick up the car?
  • What type of car is preferred?

There is a higher chance of availability the earlier the reservation is. If a reservation is cancelled however, one may still be charged.

Once the reservations are completed and confirmed, the car will then be delivered at the time and place scheduled. There will be a small card reader mounted on the windshield. Once the customer places their membership card on the reader, it will use what is called blink technology to activate the time and unlock the car. The reader will not work until it is time for that specific reservation. The keys can then be found somewhere inside the car such as the glove compartment. Depending on the company, the customer may be provided with a key to a lock box that contains the ignition key itself. Once the customer is set, they are off to their next destination.

Although members are often responsible for cleaning the car and filling up the tank when low, the car sharing company is generally responsible for the long-term maintenance of the vehicles. Members have to make sure that when they are finished, the car is ready for the next user to move on.

 in 1948, but there was no known formal development of the concept in the next few years. By the 1960s as innovators, industrialists, cities, and public authorities studied the possibility of high-technology transportation—mainly computer-based small vehicle systems (almost all of them on separate guideways)—it was possible to spot some early precursors to present-day service ideas and control technologies.

, as well as smaller operators such as Australia's Charter Drive Car Share.

For future applications, many car sharing companies are now investing in plug-in hybrid electric vehicles (PHEV). With the use of these types of vehicles, cost of gas consumption can be greatly reduced. Since most customers do not need the vehicle for long amounts of time or distance, it gives the car sharing company time to collect and recharge these vehicles for additional use. This application can greatly reduce carbon emissions and improve city environments.

Also, car sharing can be considered as an example of a technological change in consumption, which is a ‘process of mutual adjustment between innovation and its socio-economic environment.’ This type of innovation poses much potential due to the current state of technological change based on today’s passenger transportation capabilities.

Other countries are already moving into designing concept cars that is solely based as an urban public vehicle. The Phiaro P70t Conch, Japan’s new concept vehicle, is a completely battery powered, three-seater vehicle which was designed for the purpose of car sharing. The vehicle was made to be small and compact enough to be driven around urban environments without sacrificing parking. The promotion of these kinds of concept vehicles have caught the attention of automotive companies worldwide.
