Public transport (also public transportation or public transit) 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 and trains, rapid transit (metro/subways/undergrounds etc) and ferries. Public transport between cities is dominated by airlines, coaches, and intercity rail. High-speed rail networks are being developed in many parts of the world.

Most public transport runs to a scheduled timetable with the most frequent services running to a headway. Share taxi offers on-demand services in many parts of the world and some services will wait until the vehicle is full before it starts. Paratransit is sometimes used in areas of low-demand and for people who need a door-to-door service.^[1]

Urban public transport may be provided by one or more private transport operators or by a transit authority. Public transport services are usually funded by government subsidies and fares charged to each passenger. Services are normally regulated and possibly subsidized from local or national tax revenue. Fully subsidized, zero-fare (free) services operate in some towns and cities.

For historical and economic reasons, there are differences internationally regarding use and extent of public transport. While countries in Old World tend to have extensive and frequent systems serving their old and dense cities, many cities of the New World have more sprawl and much less comprehensive public transport.

History[link]

Early trolley car in Newton, Massachusetts

Conveyances for public hire are as old as the first ferries, and the earliest public transport was water transport: on land people walked (sometimes in groups and on pilgrimages, as noted in sources such as the Bible and Canterbury Tales) or (at least in the Old World) rode an animal.^[2] Ferries are part of Greek mythology – corpses in ancient Greece were buried with a coin underneath their tongue to pay the ferryman Charon to take them to Hades^{[citation needed]}.

Some historical forms of public transport are the stagecoach, traveling a fixed route from coaching inn to coaching inn, and the horse-drawn boat carrying paying passengers, which was a feature of European canals from their 17th-century origins. (The canal itself is a form of infrastructure dating back to antiquity – it was used at least for freight transportation in ancient Egypt to bypass the Aswan cataract – and the Chinese also built canals for transportation as far back as the Warring States period.^[3] Whether or not those canals were used for for-hire public transport is unknown; the Grand Canal was primarily used for shipping grain.)

The omnibus, the first organized public transit system within a city, appears to have originated in Paris, France, in 1662,^[4] although the service in question failed a few months after its founder died; omnibuses are next known to have appeared in Nantes, France, in 1826. The omnibus was introduced to London in July 1829.^[5]

The first passenger horse-drawn railway was opened in 1806 between Swansea and Mumbles.^[6] In 1825, George Stephenson built the Locomotion for the Stockton and Darlington Railway, north east England, which was the first public steam railway in the world.

Mode[link]

Airline[link]

An airline provides scheduled service with aircraft between airports. Air travel has high up to very high speeds, but incurs large waiting times prior and after travel, and is therefore often only feasible over longer distances or in areas where lack of ground infrastructure makes other modes of transport impossible. Bush airlines work more similar to bus stops; an aircraft waits for passengers and takes off when the aircraft is full.

Bus and coach[link]

Bus services use buses on conventional roads to carrying numerous passengers on shorter journeys. Buses operate with low capacity (i.e. compared with trams or trains), and can operate on conventional roads, with relatively inexpensive bus stops to serve passengers. Therefore buses are commonly used in smaller cities and towns, in rural areas as well for shuttle services supplementing in large cities. Bus rapid transit is an ambiguous term used for buses operating on dedicated right-of-way, much like a light rail. Trolleybuses are electric buses that employ overhead wires to get power for traction. Online Electric Vehicles are buses that run on a conventional battery, but are recharged frequently at certain points via underground wires.^[7]

Coach services use coaches (long-distance buses) for suburb-to-CBD or longer distance transportation. The vehicle are normally equipped with more comfortable seating, a separate luggage compartment, video and possibly also a toilet. They have higher standards than city buses, but a limited stopping pattern.

Train[link]

Right: Chicago Transit Authority control tower 18 guides elevated Chicago 'L' northbound Purple and Brown lines intersecting with westbound Pink and Green lines and the looping Orange line above the Wells and Lake street intersection in the loop.

Passenger rail transport is the conveyance of passengers by means of wheeled vehicles specially designed to run on railways. Trains allow high capacity on short or long distance, but require track, signalling, infrastructure and stations to be built and maintained. Urban rail transit consists of trams, light rail, rapid transit, people movers, commuter rail, monorail suspension railways and funiculars.

Commuter, intercity, and high-speed rail[link]

Chhatrapati Shivaji Terminus in Mumbai, India

Commuter rail is part of an urban area's public transport; it provides faster services to outer suburbs and neighboring towns and villages. Trains stop at all stations, that are located to serve a smaller suburban or town center. The stations often being combined with shuttle bus or park and ride systems at each station. Frequency may be up to several times per hour, and commuter rail systems may either be part of the national railway, or operated by local transit agencies.

Intercity rail is long-haul passenger services that connect multiple urban areas. They have few stops, and aim at high average speeds, typically only making one of a few stops per city. These services may also be international.

High-speed rail is passenger trains operating significantly faster than conventional rail—typically defined as at least 200 kilometres per hour (120 mph). The most predominant systems have been built in Europe and Japan, and compared with air travel, offer long-distance rail journeys as quick as air services, have lower prices to compete more effectively and uses electricity instead of combustion.^[8]

Tram and light rail[link]

Trams are railborne vehicles that run in city streets or dedicated tracks. They have higher capacity than buses, but must follow dedicated infrastructure with rails and wires either above or below the track, limiting their flexibility.

Light rail is a modern development (and use) of the tram, with dedicated right-of-way not shared with other traffic, step-free access and increased speed. Light rail lines are, thus, essentially modernized interurbans.

Rapid transit[link]

The Vancouver SkyTrain is the longest automated rapid transit system in the world. It also includes the longest mass transit-only bridge, the Skybridge (TransLink).

A rapid transit railway system (also called a metro, underground, or subway) operates in an urban area with high capacity and frequency, and grade separation from other traffic.^[9][10]

Systems are able to transport large amounts of people quickly over short distances with little land use. Variations of rapid transit include people movers, small-scale light metro and the commuter rail hybrid S-Bahn. More than 160 cities have rapid transit systems, totalling more than 8,000 km (4,971 mi) of track and 7,000 stations. Twenty-five cities have systems under construction.

Personal rapid transit[link]

A vehicle on WVU's Morgantown Personal Rapid Transit

Personal rapid transit is an automated cab service that runs on rails or a guideway. This is an uncommon mode of transportation (excluding elevators) due to the complexity of automation. A fully implemented system might provide most of the convenience of individual automobiles with the efficiency of public transit. The crucial innovation is that the automated vehicles carry just a few passengers, turn off the guideway to pick up passengers (permitting other PRT vehicles to continue at full speed), and drop them off to the location of their choice (rather than at a stop). Conventional transit simulations show that PRT might attract many auto users in problematic medium density urban areas. A number of experimental systems are in progress. One might compare personal rapid transit to the more labor-intensive taxi or paratransit modes of transportation, or to the (by now automated) elevators common in many publicly accessible areas.

Cable-propelled transit[link]

Metrocable (Medellín) gondola lifts serving the barrios of Medellín, Colombia

Cable-propelled transit (CPT) is a transit technology that moves people in motor-less, engine-less vehicles that are propelled by a steel cable.^[11] There are two sub-groups of CPT – Gondola lifts and Cable car (railway). Gondola lifts are supported and propelled from above by cables whereas cable cars are supported and propelled from below by cables.

While historically associated with usage in ski resorts, gondola lifts are now finding increased consumption and utilization in many urban areas – built specifically for the purposes of mass transit.^[12] Many, if not all, of these systems are implemented and fully integrated within existing public transportation networks. Examples include Metrocable (Medellín), Metrocable (Caracas), Portland Aerial Tram, and Roosevelt Island Tramway.

London will soon see a gondola lift system implemented in the city as the proposed Thames Gateway Cable Car was approved by council in January 2011.^[13]

Ferry[link]

Maritime public transport in Buenos Aires

A ferry is a boat or ship, used to carry (or ferry) passengers, and sometimes their vehicles, across a body of water. A foot-passenger ferry with many stops is sometimes called a water bus. Ferries form a part of the public transport systems of many waterside cities and islands, allowing direct transit between points at a capital cost much lower than bridges or tunnels, though at a lower speed. Ship connections of much larger distances (such as over long distances in water bodies like the Mediterranean Sea) may also be called ferry services.

Motorcycle[link]

In the Philippines and elsewhere, motorcycles are used as public transportation. The motorcycles can be used singly or with a sidecar attached, the latter often referred to as "tricycles". They can either be hired for personal trips, like a taxi, or used for shared trips, with set routes, like a bus.

Pedicabs[link]

Trisikads in Metro Manila

Pedicabs are common in poorer or more crowded places and can take various shapes and sizes. In the Philippines, they are called trisikads and are just a regular bike with a sidecar attached.

Operation[link]

Infrastructure[link]

All public transport runs on infrastructure, either on roads, rail, airways or seaways; all consists of interchanges and way. The infrastructure can be shared with other modes of transport, freight and private transport, or it can be dedicated to public transport. The latter is especially true in cases where there are capacity problems for private transport. Investments in infrastructure are high, and make up a substantial part of the total costs in systems that are expanding. Once built, the infrastructure will further require operating and maintenance costs, adding to the total costs of public transport. Sometimes governments subsidize infrastructure by providing it free of charge, just like is common with roads for automobiles.

Interchanges[link]

Interchanges are locations where passengers can switch mode. Most interchanges are predominantly for passenger to change from being pedestrians to passengers (such as a bus stop), while each system will have a few hubs that allow passengers to change between vehicles. This may be between vehicles of the same mode (like a bus interchange), or it can be between local and intercity transport (such as at a central station or airport). Other interchange facilities include car parks and bicycle parking.

Timetables[link]

Timetables (or 'schedules' North American English) are provided by the transport operator to allow potential users to plan their journeys, often supplemented with maps and fare schemes to help travelers coordinate their travel. Online public transport route planners, sometimes combined with pre-sold tickets, help make planning easier. Services are often arranged to operate at regular intervals throughout the day (known as clock-face scheduling). In most locations, extra services or even extra routes are operated during the morning and evening rush hours.

Coordination between services at intersections is important to reduce the total travel time for passengers. This can be done by coordinating shuttle services with main routes, or by creating a fixed time (for instance twice per hour) when all bus and rail routes meet at a station and exchange passengers.

Financing[link]

The main sources of financing are ticket revenue, government subsidies and advertisement. The percentage of revenue from passenger charges is known as the farebox recovery ratio. A limited amount of income may come from land development and rental income from stores and vendors, parking fees, and leasing tunnels and rights-of-way to carry fiber optic communication lines.

Fare and ticketing[link]

A contactless ticket validator used in Oslo, Norway

Most—but not all—public transport required the purchase of a ticket to generate revenue for the operators. Tickets may either be bought in advance, at the time of the ride, or the carrier may allow both methods. Passengers may be issued with a paper ticket, metal or plastic token, or an electronic card (smart card, contactless smart card). Sometimes a ticket has to be validated, e.g. a paper ticket that has to be stamped, or an electronic ticket that has to be checked in.

Tickets may be valid for a single (or return) trip, or valid within a certain area for a period of time. The fare is based on the travel class, either as a function of the traveled distance, or based on a zone pricing.

The tickets may have to be shown or checked automatically at the station platform or when boarding, or during the ride by a conductor. Operators may choose to control all riders, allowing sale of the ticket at the time of ride. Alternatively, a proof-of-payment system allows riders to enter the vehicles without showing the ticket, but riders may or may not be controlled by a ticket controller; if the rider fails to show proof of payment, the operator may fine the rider at the magnitude of the fare.

Multi-use tickets allow travel more than once. In addition to return tickets, this includes period cards allowing travel within a certain area (for instance month cards), or during a given number of days that can be chosen within a longer period of time (for instance eight days within a month). Passes aimed at tourists, allowing free or discounted entry at many tourist attractions, typically include zero-fare public transport within the city. Period tickets may be for a particular route (in both directions), or for a whole network. A free travel pass allowing free and unlimited travel within a system is sometimes granted to particular social sectors, for example students, elderly, children, employees (job ticket) and the physical or mentally disabled.

Zero-fare public transport services are funded in full by means other than collecting a fare from passengers, normally through heavy subsidy or commercial sponsorship by businesses. Several mid-size European cities and many smaller towns around the world have converted their entire bus networks to zero-fare. Local zero-fare shuttles or inner-city loops are far more common than city-wide systems. There are also zero-fare airport circulators and university transportation systems.

Revenue, profit and subsidies[link]

This section may contain original research. Please improve it by verifying the claims made and adding references. Statements consisting only of original research may be removed. More details may be available on the talk page. (December 2008)

Governments frequently opt to subsidize public transport, for social, environmental or economic reasons. Common motivations include: the desire to provide transport to people who are unable to use an automobile,^[14] and to reduce congestion, land use and automobile emissions. Other motives may include promoting business and economic growth, or urban renewal in formerly deprived areas of the city. Public transit systems rarely operate without government support. Some systems are owned and operated by a government agency, where other transportation services may be commercial, but receive special benefits from the government compared to a normal company.

Subsidies may take the form of direct payments to financially unprofitable services, but support may also include indirect subsidies. For example, the government may allowing use of state-owned infrastructure without payment, or at a reduced cost (e.g. railways and roads), to stimulate public transport's economic competitiveness over private transport, that normally also has free infrastructure (subsidized through such things as gas taxes). Other subsidies include tax advantages (for instance aviation fuel is typically not taxed), bailouts if companies that are likely to collapse (often applied to airlines) and reduction of competition through licensing schemes (often applied to taxis and airlines). Private transport is normally subsidized indirectly through free roads and infrastructure,^[15] as well as incentives to build car factories^[16] and, on occasion, directly via bailouts of automakers.^[17][18]

Land development schemes may be initialized, where operators are given the rights to use lands near stations, depots, or tracks for property development. For instance, in Hong Kong, MTR Corporation Limited and KCR Corporation generate profits from land development to cover the partial cost of construction, but not operation, of the urban rail systems.

Some supporters of mass transit believe that use of taxpayer capital to fund mass transit will ultimately save taxpayer money in other ways,^{[citation needed]} and therefore, state-funded mass transit is a benefit to the taxpayer. Some research has supported this position,^[19] but the measurement of benefits and costs is a complex and controversial issue.^[20] A lack of mass transit results in more traffic, pollution,^[21][22][23] and road construction^[24] to accommodate more vehicles, all costly to taxpayers;^[25] providing mass transit will therefore alleviate these costs.^[26] (Perhaps,^{[27][28][29][30]} although right-wing think tanks disagree^[31][32])

Safety and security[link]

Expansion of public transportation systems is often opposed (particularly in the United States) by critics who see them as vehicles for violent criminals and homeless persons to expand into new areas (to which they would otherwise have to walk).^[33] According to the Transportation Research Board, "[v]iolent crime is perceived as pandemic .... Personal security affects many peoples' [sic] decisions to use public transportation."^[34] Despite the occasional highly publicized incident, the vast majority of modern public transport systems are well designed and patrolled and generally have low crime rates. Many systems are monitored by CCTV, mirrors, or patrol.^[35]

Nevertheless, some systems attract vagrants who use the stations or trains as sleeping shelters, though most operators have practices that discourage this.^[35]

Though public transit accidents attract far more publicity than car wrecks, public transport has much lower accident rates. Annually, public transit prevents 200,000 deaths, injuries, and accidents had equivalent trips been made by car. The National Safety Council estimates riding the bus as over 170 times safer than private car.^[36]

Impact[link]

Environmental[link]

Although there is continuing debate as to the true efficiency of different modes of transportation, mass transit is generally regarded as significantly more energy efficient than other forms of travel. A 2002 study by the Brookings Institution and the American Enterprise Institute found that public transportation in the U.S uses approximately half the fuel required by cars, SUV's and light trucks. In addition, the study noted that "private vehicles emit about 95 percent more carbon monoxide, 92 percent more volatile organic compounds and about twice as much carbon dioxide and nitrogen oxide than public vehicles for every passenger mile traveled".^[37]

A 2004 study from Lancaster University concluded that there was no environmental benefit to be gained from persuading car or plane travelers to switch to trains. Environmental group Friends of the Earth were skeptical of the findings, claiming the results are not in line with previous studies.^[38] The study showed that trains had failed to keep up with the advances that the automotive and aviation industries had made in improved fuel efficiency. Express trains travelling from London to Edinburgh consumed 11.5 litres more fuel per seat than a modern diesel car and Pendolino trains weigh more per seat than the Airbus A380 airliner. A representative from Modern Railways magazine is reported as having said:^{[citation needed]}

"I know this will generate howls of protest, but at present a family of four going by car is about as environmentally friendly as you can get."

Studies have shown that there is a strong inverse correlation between urban population density and energy consumption per capita, and that public transport could facilitate increased urban population densities, and thus reduce travel distances and fossil fuel consumption.^[39]

Supporters of the green movement usually advocate public transportation, because it offers decreased airborne pollution compared to automobiles. A study conducted in Milan, Italy in 2004 during and after a transportation strike serves to illustrate the impact that mass transportation has on the environment. Air samples were taken between 2 and 9 January, and then tested for Methane, Carbon Monoxide, non-methane Hydrocarbons (NMHCs), and other gases identified as harmful to the environment. The figure below is a computer simulation showing the results of the study “with 2 January showing the lowest concentrations as a result of decreased activity in the city during the holiday season. 9 January showed the highest NMHC concentrations because of increased vehicular activity in the city due to a public transportation strike.”^[40]

Based on the benefits of public transport, the green movement has impacted public policy. For example, the state of New Jersey released Getting to Work: Reconnecting Jobs with Transit.^[41] This initiative attempts to relocate new jobs into areas with higher public transportation accessibility. The initiative cites the use of public transportation as being a means of reducing traffic congestion, providing an economic boost to the areas of job relocation, and most importantly, contributing to a green environment by reducing carbon dioxide (CO2) emissions.

Using Public transportation can result in a reduction of an individual’s carbon footprint. A single person, 20-mile round trip by car can be replaced using public transportation and result in a net CO2 emissions reduction of 4,800 lbs/year.^[42] Using public transportation saves CO2 emissions in more ways than simply travel as public transportation can help to alleviate traffic congestion as well as promote more efficient land use. When all three of these are considered, it is estimated that 37 million metric tones of CO2 will be saved annually.^[42] Another study claims that using public transit instead of private in the U.S. in 2005 would have reduced CO2 emissions by 3.9 million metric tones and that the resulting traffic congestion reduction accounts for an additional 3.0 million metric tons of CO2 saved.^[43] This is a total savings of about 6.9 million metric tones per year given the 2005 values.

In order to compare energy impact of public transportation to private transportation, the amount of energy per passenger mile must be calculated. The reason that comparing the energy expenditure per person is necessary is to normalize the data for easy comparison. Here, the units are in per 100 p-km (read as person kilometer or passenger kilometer). In terms of energy consumption, public transportation is better than individual transport in a personal vehicle.^[44] In England, bus and rail are popular methods of public transportation, especially London. Rail provides rapid movement into and out of the city of London while busing helps to provide transport within the city itself. As of 2006–2007, the total energy cost of London’s trains was 15 kWh per 100 p-km, about 5 times better than a personal car.^[45] For busing in London, it was 32 kWh per 100 p-km, or about 2.5 times that of a personal car.^[45] This includes lighting, depots, inefficiencies due to capacity (i.e., the train or bus may not be operating at full capacity at all times), and other inefficiencies. Efficiencies of transport in Japan in 1999 were 68 kWh per 100 p-km for a personal car, 19 kWh per 100 p-km for a bus, 6 kWh per 100 p-km for rail, 51 kWh per 100 p-km for air, and 57 kWh per 100 p-km for sea.^[45] These numbers from either country can be used in energy comparison calculations and/or life cycle assessment calculations.

Public transportation also provides an arena to test environmentally friendly fuel alternatives, such as hydrogen-powered vehicles. Swapping out materials to create lighter public transportation vehicles with the same or better performance will increase environmental friendliness of public transportation vehicles while maintaining current standards or improving them. Informing the public about the positive environmental effects of using public transportation in addition to pointing out the potential economic benefit is an important first step towards making a difference.

Land use[link]

Traffic jam in São Paulo

Urban space is a precious commodity and public transport consumes it more efficiently than a car dominant society, allowing cities to be built more compactly than if they were dependent on automobile transport.^[46] If public transport planning is at the core of urban planning, it will also force cities to be built more compactly to create efficient feeds into the stations and stops of transport.^[47] This will at the same time allow the creation of centers around the hubs, serving passengers' need for their daily commercial needs and public services. This approach significantly reduces urban sprawl.

Social[link]

An important social role played by public transport is to ensure that all members of society are able to travel, not just those with a driving license and access to an automobile—which include groups such as the young, the old, the poor, those with medical conditions, and people banned from driving. Automobile dependency is a name given by policy makers to places where those without access to a private vehicle do not have access to independent mobility.^[48]

Above that, public transportation opens to its users the possibility of meeting other people, as no concentration is diverted from interacting with fellow-travelers due to any steering activities. Adding to the above-said, public transport becomes a location of inter-social encounters across all boundaries of social, ethnic and other types of affiliation.

Economic[link]

Public transport allows transport at an economy of scale not available through private transport. Advocates of public transport claim that investing in mass transit will ultimately reduce the total transport cost for the public. Time saved can also be significant, as less cars can translate to less congestion, and faster speeds for remaining motorists. Transit-oriented development can both improve the usefulness and efficiency of the public transit system as well as result in increased business for commercial developments.

Because of the increased traffic and access to transit systems, putting in public transit frequently has a positive effect on real estate prices. For example, the Washington DC Metro system has increased land desirability around its stations, and The Hong Kong metro MTR generates a profit by redeveloping land around its stations. Much public opposition to new transit construction can be based on the concern about the impact on neighborhoods of this new economic development.^{[citation needed]} Few localities have the ability to seize and reassign development rights to a private transit operator, as Hong Kong has done.

Investment in public transport also has secondary positive effects on the local economy, with between $4 and $9 of economic activity resulting from every dollar spent.^[1] Many businesses rely on access to a transit system, in particular in cities and countries where access to cars is less widespread, businesses which require large amounts of people going to a same place may not be able to accommodate a large number of cars (concert venues, sport stadia, airports, exhibitions centres,...), or businesses where people are not able to use a car (bars, hospitals, or industries in the tourism sector whose customers may not have their cars). Transit systems also have an effect on derivated businesses: commercial websites have been founded, such as Hopstop.com, that give directions through mass transit systems; in some cities, such as London, products themed on the local transport system are a popular tourist souvenir.

However, public transport projects frequently have very large upfront costs, requiring large investments from either local government or private investors. Initial estimates of project cost and timescale are frequently underestimated, and nearly all public transport requires government subsidies and/or direct government support in order to remain operational.

The existence of a transit system can lower land values in some cases, either through influence on a region's demographics and crime rate (actual or perceived), or simply through the ambient noise and other discomforts the system creates.

Regulations[link]

Food and drink[link]

Longer distance public transport sometimes sell food and drink on board, and/or have a dedicated buffet car and/or dining car. However, some urban transport systems forbid the consumption of food, drink, or even chewing gum when riding on public transport. Sometimes only types of food are forbidden with more risk of making the vehicles dirty, e.g. ice creams and French fries, and sometimes potato chips.^{[citation needed]}

Some systems prohibit carrying open food or beverage containers, even if the food or beverage is not being consumed during the ride.

Smoking[link]

In the United States, India, Canada, most of the European Union, Australia, and New Zealand, smoking is prohibited in all or some parts of most public transportation systems due to safety and health issues. Generally smoking is not allowed on buses and trains, while rules concerning stations and waiting platforms differ from system to system. The situation in other countries varies widely.

Noise[link]

Many mass transit systems prohibit the use of audio devices, such as radios, CD players, and MP3 players unless used with an earphone through which only the user can hear the device.

Some mass transit systems have restricted the use of mobile phones. Long distance train services, such as the Amtrak system in the US, have "quiet cars" where mobile phone usage is prohibited.

Some systems prohibit passengers from engaging in conversation with the operator. Others require that passengers who engage in any conversation must keep the noise level low enough that it not be audible to other passengers.

Some systems have regulations on the use of profanity. In the United States, this has been challenged as a free speech issue.

Banned items[link]

Certain items considered to be problematic are prohibited or regulated on many mass transit systems. These include firearms and other weapons (unless licensed to carry), explosives, flammable items, or hazardous chemicals and substances.

Many systems prohibit live animals, but allow those that are in carrying cases or other closed containers. Additionally, service animals for the blind or disabled are permitted.

Some systems prohibit items of a large size that may take up a lot of space, such as bicycles. But more systems in recent years have been permitting passengers to bring bikes.

In Sydney, it is illegal to carry spray cans or permanent markers on public transport, as they can be used to vandalise the vehicles and stations. This rule also applies to sharp instruments that could damage the train, such as screwdrivers that could be used to make "scratchitti", a form of vandalism where tags are carved into a window.^{[citation needed]}

Other regulations[link]

Many systems have regulations against behavior deemed to be unruly or otherwise disturbing to other passengers. In such cases, it is usually at the discretion of the operator, police officers, or other transit employees to determine what behaviors fit this description.

Some systems have regulations against photography or videography of the system's vehicles, stations, or other property. Those seen holding a mobile phone in a manner consistent with photography are considered to be suspicious for breaking this rule. This is another issue that is challenged in the courts in the United States as a "Free Speech" issue.

Sleeping[link]

In the era when long distance trips took several days, sleeping accommodations were an essential part of transportation. (On land, the lodging involved was often part of the infrastructure: the inn or ryokan, which did not move, sheltered travelers. People also slept on ships at sea.) Today, most airlines, inter-city trains and coaches offer reclining seats and many provide pillows and blankets for overnight travelers. Better sleeping arrangements are commonly offered for a premium fare and include sleeping cars on overnight trains, larger private cabins on ships and airplane seats that convert into beds. Budget-conscious tourists sometimes plan their trips using overnight train or bus trips in lieu of paying for a hotel. The ability to get additional sleep on the way to work is attractive to many commuters using public transport.

Because night trains or coaches can be cheaper than motels, homeless persons often use these as overnight shelters, as with the famous Line 22 ("Hotel 22") in Silicon Valley.^[49][50] Specifically, 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. Even a low fare in some cases often deters the poorest individuals, including homeless people.

In 2010, McIntyre released his autobiography, Life and Laughing: My Story, and also became the youngest-ever host of the Royal Variety Performance.^[3] He started as a judge on the fifth series of Britain's Got Talent in April 2011.^[4] He is to embark on his second nationwide tour in 2012.^[5]

Early life[link]

McIntyre was born in Merton, southwest London, and raised in Hampstead.^[6] McIntyre's parents were both in show business: his Canadian father, Ray Cameron (19 April 1938 – 27 December 1993), né Thomas Cameron McIntyre, was a writer on The Kenny Everett Television Show, and his Hungarian mother, Kati, was a dancer. McIntyre has some Eastern European Jewish heritage on his mother's side.^[7][8] His parents divorced when he was seven; both his parents remarried and went on to have other children with their new spouses. Ray Cameron relocated to Los Angeles, where he died of a heart attack in 1993, aged 55.

Education[link]

McIntyre went to Arnold House Prep School and then attended Merchant Taylors' School, Northwood for three years before transferring to local state school Woodhouse College for financial reasons.^[9] McIntyre later attended Edinburgh University for one year before dropping out to pursue a career in script writing.^[10] He has said that he cannot remember whether it was biology or chemistry that he studied while there.^[6][10]

Career[link]

Television and stage[link]

McIntyre has appeared three times on BBC One's Live at the Apollo and also on the Royal Variety Performance, in 2006, 2008 and 2010. While performing on stage in Wolverhampton in 2008, as he was running back onto stage for his encore, McIntyre tripped, fell over and dislocated his shoulder. Many of the audience believed this to be part of his act and started to laugh; only after his manager came on stage to assist did they realise it was real.^[11]

McIntyre's routine on We Are Most Amused, staged at the New Wimbledon Theatre on 12 November 2008 in aid of The Prince's Trust was televised. This comedy gala celebrated the 60th birthday of Prince Charles, and was performed in the presence of the Prince of Wales and his wife the Duchess of Cornwall.^{[citation needed]}

David Khari Webber "Dave" Chappelle^[4] (/ʃəˈpɛl/; born August 24, 1973)^[1] is an American comedian, screenwriter, television/film producer, actor, and artist. Chappelle began his film career in the film Robin Hood: Men in Tights in 1993 and continued to star in minor roles in the films The Nutty Professor, Con Air, and Blue Streak. His first lead role in a film was in Half Baked in 1998. In 2003, he became widely known for his popular sketch comedy television series, Chappelle's Show, which ran until his abrupt retirement from the show in 2005. Chappelle is ranked forty-third in Comedy Central Presents: 100 Greatest Stand-Ups of All Time.^[5]

Early life[link]

Chappelle was born David Khari Webber Chappelle in Washington, D.C. on August 24, 1973.^[1][2] His father, William David Chappelle III, was a professor at Antioch College in Yellow Springs, Ohio.^[2] His mother, Yvonne (née Reed), was a professor at Howard University, Prince George's Community College, and the University of Maryland and is also a Unitarian Universalist minister.^[6][7][8] Chappelle grew up in Silver Spring, Maryland and attended Woodlin Elementary School.^[2] During young Chappelle's formative years, his comic inspiration came from various comedians, particularly Eddie Murphy and Richard Pryor.^[2]

After his parents separated, Chappelle stayed in Washington with his mother while spending summers with his father in Ohio. In 1991, he graduated from Washington's Duke Ellington School of the Arts where he studied theatre arts.^[2]

Chappelle moved to New York City to pursue a career as a comedian. He gathered the courage to perform at Harlem's famed Apollo Theater in front of the infamous "Amateur Night" audience. The performance resulted in him being booed off the stage. Chappelle has described the experience as the moment that gave him the courage to continue his show business aspirations.^[2] He quickly made a name for himself in the New York comedy circuit, even performing in the city's parks. At the age of 19, Chappelle made his film debut as "Ahchoo" in Mel Brooks' Robin Hood: Men in Tights. In the same year, Chappelle was offered the role of Benjamin Buford "Bubba" Blue in Forrest Gump. Concerned about what seemed to be a racially demeaning character, he turned down the part; the film would go on to win Academy Award for Best Picture that year. He has since admitted to regretting the decision.^[9] Chappelle played another supporting movie role in 1994's little-seen Getting In.

He attracted the attention of TV network executives and developed numerous pilots but none of them were picked up for series.^[2][10] In 1995, he made a guest appearance in an episode of ABC's highly rated sitcom Home Improvement. The storyline had Chappelle and real-life friend comedian Jim Breuer ask Tim Taylor for advice on their girlfriends. The characters' single outing in the episode proved so popular that ABC decided to give them their own spin-off sitcom titled Buddies. However, after taping a pilot episode, Jim Breuer was fired and replaced with actor Christopher Gartin. Buddies premiered in March 1996 to disappointing ratings. The show was cancelled after only four episodes out of thirteen that were produced. Nine years later, in May 2005, ten of the episodes were released on a single-disc DVD to capitalize on Chappelle's new-found fame.

After the failure of Buddies, Chappelle starred in another pilot. According to Chappelle, the network was uncomfortable with the African-American cast and wanted white actors added. Chappelle resisted and subsequently accused the network of racism. Shortly after this incident, Chappelle's father died. Chappelle returned to Ohio and considered leaving the entertainment business.^[2][10]

He later appeared as a nightclub comedian in the 1996 comedy The Nutty Professor starring Eddie Murphy, one of his major comedic influences. He also had a minor role in 1997's Con Air. He and Neal Brennan co-wrote the 1998 cult stoner film Half Baked, Chappelle's first starring role, about a group of marijuana-smoking friends trying to get their friend out of jail. That same year, he appeared in "Pilots and Pens Lost", a 1998 episode of The Larry Sanders Show's sixth season, in which he and the executives of the show's nameless television network satirized the treatment to which scriptwriters and show creators were subjected, as well as the executives' knee-jerk tendencies toward racial stereotypes. In December of that year Chappelle appeared as Tom Hanks' friend and confidant in You've Got Mail. In 1999, he appeared in the Martin Lawrence film Blue Streak.

In 2000, Chappelle recorded his first HBO special, Dave Chappelle: Killin' Them Softly, in Washington, DC.^[11] He followed this up with an appearance as "Conspiracy Brother" in the 2002 racial satire Undercover Brother.

[edit] 2003–2006: Standup and Chappelle's Show

In 2003, Chappelle debuted his own weekly sketch comedy show on Comedy Central called Chappelle's Show. The show parodied many aspects of American culture including racial stereotypes, politics and pop culture. Along with comedy skits, the show also featured musical performances by mostly hip-hop and soul artists.
