Public transport, public transportation, public transit or mass transit comprises all transport systems in which the passengers do not travel in their own vehicles. While it is generally taken to include rail and bus services, wider definitions would include scheduled airline services, ferries, taxicab services etc. — any system that transports members of the general public. A further restriction that is sometimes applied is that it should take place in shared vehicles, which would exclude taxis that are not shared-ride taxis.
The term public transport is preferred in the British Isles and most Commonwealth countries, whereas public transportation, public transit or mass transit are usually used in North America.
Public transport can be faster than other modes of travel where a separate infrastructure is used and thus much higher speeds are possible than are permitted on roads. Prime examples are in cities where road congestion can be avoided (metro), and for long distance travel (trains). On roads this is also possible if the public transportation has its own separate lanes. However, in reality the lanes are often shared, in which case public transport on roads is usually slower due to the (frequent) stops and changeovers. Additionally, public transport system may be poorly developed and thus may take up to two or even three times longer than an equivalent trip in a private vehicle.
Increased road traffic congestion and improved transit systems are reducing or eliminating this disparity in many areas, and public transport use rises sharply with population density. Ultimately, if all transport were public (in the sense of shared), more people per vehicle would mean fewer vehicles on the roads, thus reducing and probably even eliminating traffic jams. Additionally, it would be easier to centrally coordinate the flow of traffic with phased traffic lights, eliminating the usually frequent stops at traffic lights and the absence of parked cars would even create space for extra lanes. Thus, public transportation is potentially much faster than private transportation, though this is rarely the case in practice. Cases where (individually faster) private transport competes against (collectively faster) public transport in densely populated areas are manifestations of the multiple prisoner's dilemma problem.
The term rapid transit refers to fast public transport in and around cities, such as metro systems (metropolitan rail). The distinction between (national) rail, metro and tram is sometimes blurred, such as in Amsterdam and the wider Randstad area, where trains often run once every 10 minutes, thus taking on the role of a metro, the metro is only partly underground and the so-called light rail is basically a tram that runs on metro lines.
Some historic forms of public transport are the stagecoach, travelling an appointed route from inn to inn, and the horse-drawn boat carrying paying passengers, which was a feature of canal systems from their 17th-century origins.
The omnibus, the first organized public transit system within a city, appears to have been originated in Nantes, France, in 1826.
Some of these types are often not for use by the general public, e.g. elevators in offices and apartment buildings, buses for personnel or school children, etc.
In addition one can alight from and usually board a taxi at any road where stopping is allowed. Some fixed route buses allow getting on and off at suitable unmarked locations along that route, typically called a hail-and-ride section.
Different arrangements for fare collection are in use. Depending on the type, fares:
Riders may be issued a paper ticket, metal or plastic token, or an electronic card.
Passes may be for a particular route (in both directions), or for a whole network.
Some systems are owned and operated by a government agency; other transportation services may be commercial, but receive greater benefits from the government compared to a normal company, e.g.,
One reason many cities spend large sums on their public transport systems is that heavy automobile traffic congests city streets and causes air pollution. It is believed that well maintained, high volume public transport systems alleviate this. Many complex factors affect the outcome of spending in public transport, so success in reducing car traffic is not always assured.
Some city councils fund public transport infratructure for strategic reasons, either to promote business and economic growth, or to regenerate deprived ares of the city. Examples of public transport planned according to this philosophy are the Docklands Light Rail and Crossrail projects in London.
Another reason for subsidies for public transit are the provision of mobility to those who cannot afford or are physically incapable of using an automobile and those who reject its use on convenience, environmental or safety grounds.
These include local urban and suburban bus and paratransit services, light rail, heritage streetcar systems, cable car, subway, rapid transit, and commuter rail services.
Special rural transportation programs of the FTA and some state governments provide assistance for bus and paratransit services in some areas.
Currently, Arlington, Texas (pop. 360,000) is the largest city in the United States without public transportation. New York City has the most extensive transit system in the country. About one in every three users of mass transit in the United States and two-thirds of the nation's rail riders live in New York City.
Translating economic impact into a steady source of revenue for public transport construction and operation has been a dream for most urban planners. Few localities have the ability to assign development rights to a private transit operator, as Hong Kong has done, though their success illustrates the potential of this idea.
Others argue that public transit is a failed initiative because of its high expense and ineffectiveness. They claim the per-mile construction and maintenance costs of constructing a subway or light rail line often equal or exceed that of an urban freeway, yet do not divert the same number of automobiles (though supporters of public transport dispute this for urban areas). Furthermore, detractors point out that public transit rarely covers its operating costs through fares (though this may be a misleading statement, since part of a freeway's "operating" cost, that of owning and maintaining vehicles, is tacitly covered by its private users). No transit agency in the U.S. has achieved this for several decades as of 2003, U.S. transit operators obtained only 32.6% of their operating funding from fares, the rest coming primarily from government subsidies *" target="_blank" >and since 1995, U.S. public transportation ridership has risen 21 percent – more than the same period's increase in roadway vehicle miles or airline passenger miles. [http://www.publictransportation.org/ Several U.S. states that were considered bastions of highway-only thinking, such as Colorado and Utah had approved major public transportation investments by 2005.
Despite the occasional highly publicized incident, the vast majority of modern public transport systems are well-patrolled and generally have low crime rates. Most transit operators have developed methods to discourage people from using their facilities for overnight shelter. Well designed transit systems are used by many social classes and new systems have a major positive impact on real estate prices. The Hong Kong metro MTR generates a profit by redeveloping land around its stations. Much public opposition to new transit construction protests the impact on neighborhoods of the new economic development public transportation attracts.
By contrast, car accidents cause an estimated 1 million fatalities per year world wide. In the United States alone there were 42,643 automobile accident fatalities in 2003, almost three times the total number of murders (14,408). Over 9 in 10 commuters in North America travel to work by car
Rules tend to be more strict in metros, trams, and buses than in non-metro trains (also in other regards, see sitting). In fact, the latter sometimes sell food and drink on board, or even have a dedicated buffet car and/or dining car. Also consuming brought-along food and drinks is allowed, except in these special carriages.
The ability to get additional sleep on the way to work is attractive to many commuters using public transportation. Some regional rail operators provide "quiet cars" where loud conversation and cell phone use are banned.
Occasionally, a local transit route with a long overnight segment and which accepts inexpensive multi-use passes will acquire a reputation as a "moving hotel" for people with limited funds. Most transportation agencies actively discourage this. For this and other reasons passengers are often required to exit the vehicle at the end of the line; they can board again in the same or another vehicle, after some waiting. Also, even a low fare often deters the poorest individuals, including homeless people.
One example of the moving homeless shelter phenomenon is the Santa Clara Valley Transportation Authority (VTA) bus line 22 * between Palo Alto, California and San Jose, California in the United States. It is often called "Hotel 22" or "Motel 22" by the homeless of Silicon Valley.Jane Lii, "Refuge On The Road: Homeless Find Nighttime Haven — The No. 22 Bus From Menlo Park To San Jose," San Jose Mercury News, 9 January 2000, 1A.Cathy Newman, "Silicon Valley: Inside the Dream Incubator," National Geographic 200, no. 6 (December 2001): 52-76. A pass for a night costs U.S. $5.25 and $61.25 for a month, much less than a hotel, house or apartment.
Another example is the Interurban rail services operated by CityRail out of Sydney, Australia. Fairly comfortable trains operate between Sydney and Lithgow or Newcastle during the night, trips of approximately 2½ hours. Age, Disability and Sole Parent pensioner excursion fares are $3.30 and $2.20 (Australian Dollars) for an all day ticket.
The New York City Subway, which operates 24 hours per day, also sees its share of homelessness, both in stations and on trains.
