Public transport

Public transport is the collective name for transport systems in which the passengers do not travel in their own vehicles. It is called public transit or mass transit in the U.S.A and Canada. While it is generally taken to mean rail and bus services, wider definitions would include scheduled airline services, ferries, taxicab services etc., basically any system which is transporting members of the general public.

The term rapid transit refers to fast public transport in and around cities, such as metro systems.

Public transport can be faster than other modes of travel; prime examples are in cities where road congestion can be avoided, and for long distance travel where much higher speeds are possible than are permitted on roads.

Forms of public transport (in the broad sense)

Aerial tramway also called Cable car or Cableway, vehicle suspended on aerial cables
Airliner
Bus normally serving a regular fixed route but could include a variable route, divert-on-demand service, see Bus rapid transit
Cable car on rails, used in cities, tram-like vehicle on rails pulled by a cable
Cable car on rails, used in mountains, see Funicular
Cable car not on rails, suspended on a cable, see Aerial tramway
Chairlift
Coach
Cog railway (or rack and pinion railway)
Conveyor transport (term includes escalators and horizontal or slightly inclined moving sidewalk - "Travolator")
Electric trolleybus
Elevator
Escalator
Ferry, including hydrofoil and air-cushion ship (Hovercraft)
Funicular, used in mountains, tram-like vehicle on rails pulled by a cable up and down a very steep slope.
Gondola lift
Helicopter
Jitney
Light rail a tram-like system with no significant sections of the route shared with cars or pedestrians
Limousine
Maglev
Metro, including rubber-tired metro
Monorail
Rickshaw
Taxicab
Train, including commuter train and high speed rail
Tram (or tramway, trolley, streetcar)
Vehicle for hire
Velotaxi
Water taxi

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, freight trains, etc.

Nodes and stops

Bus stop (including bus station, bus depot), tram stop
Metro station

- Stations of the Paris Metro
Ship terminal, landing-stage or jetty
Taxi stand

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.

Ticket systems

must be bought in advance, one can not physically enter the railway platform etc. without, due to a turnstile or guard (usually found in metro)
must be bought in advance, one can not physically enter the vehicle etc. without, due to a turnstile or guard (usually found in metro)
must be bought in advance, one is checked by a conductor, etc., upon entry (usually found on buses in North America and Western Europe)
must be bought in advance, one is checked randomly by a ticket controler (usually found in Eastern Europe)
can be bought on entering the vehicle or during the ride
sometimes the ticket can be bought both in advance and during the ride, then the fare may be higher in the latter case, see also Conductor (transportation); in this case buying in advance is often possible at the point of departure, but usually not at a tram or bus stop

Special tickets include:

passes for unlimited travel within a period of time
passes for unlimited travel during a given number of days that can be chosen within a longer period of time (e.g. 8 days within a month)
multi-ride tickets
discount tickets valid for someone with a discount pass, etc.
Smartcard
SMS tickets

Funding

Funding for public transport systems differ widely, from systems which are run as unsubsidised commercial enterprises to systems that are free of charge:

Hasselt, Belgium - free bus services
Gent - free night bus services (weekends only)
Renesse (mun. Schouwen-Duiveland), Netherlands - free bus services in the area (in summer only)
Dordrecht - bus and ferry, some saturdays at the end of each year
Noordwijk/Oegstgeest - Leiden Transferium - The Hague, express bus, running on weekdays during daytime, free of charge as a test during 2004; it is intended for commuters working in The Hague and living in Leiden or beyond who would otherwise travel by car to the Hague, to promote parking the car at the Transferium and continuing the journey by bus; the aim is to reduce road traffic congestion between Leiden and The Hague. The test is paid by the province of South Holland.
Washington, D.C - Congressional Subway - small free metro system
some ferries, such as the Staten Island Ferry.
short-distance 'public transport' such as elevator, escalator, moving sidewalk (horizontal and inclined); these are often part of a larger public transport system or business (e.g. shop) of which the products and services are not free.
free bicycle services have been run in some places.

Other transportation services may be commercial, but receive benefits from the government compared to a normal company, e.g.,

direct payments to run unprofitable services.
government bailouts it the company is likely to collapse (often applied to airlines).
tax advantages, e.g., aviation fuel is typically not taxed.
reduction of competition through licensing schemes (often applied to taxi and airline services.)
allowing use of state-owned infrastructure without payment or for less than cost-price (may apply for railways).

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 spendings in public transport, so success in reducing car traffic is not always assured.

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 environmental or safety grounds.

Public transport as a sleeping place

Public transport and its terminal buildings are sometimes used by homeless people and budget tourists as a sleeping place. This can vary from the tourist who travels on purpose at night in order to sleep while travelling and dispense with the cost of a hotel, to people for whom the 'sleeping accommodation' is the purpose, and the displacement of the vehicle a somewhat inconvenient irrelevance.

For the latter a key requirement is that travelling through the night costs less than a nearby hotel. This may especially be the case with a rail or bus pass.

One popular example is the Santa Clara Valley Transportation Authority (VTA) bus route 22, dubbed 'Hotel 22', between Palo Alto, California and San Jose, California, (Silicon Valley). A pass for 24 hours costs 4 dollars and one for a month 45 dollars, much less than a hotel, house or apartment.
