Public transport vs. private carsWhile your are reading the below post, please think about the similarities and differences between the public transport and a private car.
From:
http://en.wikipedia.org/wiki/Public_transportPublic transport, public transportation, public transit or mass transit comprise all
transport systems in which the passengers do not travel in their own vehicles. While the above terms are generally taken to include
rail and
bus services, wider definitions might 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 transit should occur in continuously shared vehicles, which would exclude taxis that are not shared-ride taxis.
In many parts of the
western world the private car currently dominates; however, in major western urban areas with good public transport systems and where the private car ownership and use is discouraged, and also in the
developing world, where private car ownership is prohibitively expensive, then walking, (motor)cycling, and public transport offer well-used alternatives. Many modern cities even in the Eastern world, are investing in public transport initiatives to increase the attractiveness and usage of public transport.
Public transport can offer significant advantages in areas with higher
population densities, due to its smaller physical and environmental footprint per rider and the problems associated with mass private car ownership and use (high parking charges and high levels of
traffic congestion).
However, road-based public transport risks being considerably very slower than private vehicles if it gets held up in general traffic congestion and to compound this scheduled transport vehicles have to make frequent stops to board additional passengers and an individual trip may require one or more transfers.
In the Western world, public transport and car advocates have been debating which mode of transport is the best with considerable differences between Europe, Asia and the United States for both historical and cultural reasons.
Europe
European cities experienced their fastest periods of growth before cars were invented and/or widespread, so they are designed for walking, cycling and tram or bus usage and a tradition of public transport and
light transport culture remains even today, even while living standards have escalated in Europe and other Western countries.
Following a period in the 1960's and 1970's during which attempts were made to accommodate the car, many countries and cities are now making sustained efforts to encourage people to use public transport. Train services are in good working order and popular in many countries in Europe with investment in high speed trains and night trains crossing many countries to compete with air travel.
United Kingdom bus usage has been rising nationally since about 1990 (although it has actually fallen by 30% in Scotland, 28% in Wales, and 22% in non-metropolitan areas in England).
[2] In
England, the number of bus journeys in 2006/07 was 12% less than it was in 1985/86, although London has seen bus journeys increase by 75% over the same period. Rail journeys increased by 53% between 1980 and 2006/007 in England, whilst
London underground journeys increased by 86% over that period.
France has built an extensive
TGV network, built
light rail, reassigned road lanes from cars to light transport in city centres and car usage and its social status has decreased there.
Germany's
AIRail Service has even replaced some airline routes.
United States
Most cities in the United States were built around the car, and in many places public transport is now almost non-existent, even in large cities, with only a few cities where public transport is in good condition, like New York City. Many public transport systems that existed prior to domination of the car were dismantled by the emergent car industry in a move came to be known as the
Great American Streetcar Scandal; nevertheless, GM managed to "rip out" over 100 streetcar systems nationwide by 1950. In the 2000s, many US cities realized that widespread car usage caused serious problems, such as
urban sprawl. In response to this, cities have begun to make their city centres more enticing, have canceled
expressways projects and restored or improved public transport and commissioned new rail transit projects.
Asia
In Asia the population density is so high that widespread car usage is very hard to sustain. Japan, a very rich country, has known this for decades and its citizens use rail transit very heavily and it is very costly and difficult to use a car there. The same is true for Singapore, where a license is required to own a car. China has historically used a lot of bicycles and mopeds, but car usage is growing quickly and is causing a lot of problems like traffic jams and pollution, but there are numerous rail transit projects under construction in China today.
Africa
In most African nations, traffic tends to be less problematic. Due to low income levels, transport options may be limited to walking, animal transport,
share taxi, and public transport where it exists. Where income levels are higher, traffic problems can arise. The most congested city in Africa is Cairo, where traffic jams can last many hours.
Economic impact
Emissions from road vehicles account for over 50% of U.S.
air pollution. For every passenger mile traveled, public transportation uses less than one half of the fuel of private automobiles, producing 5% as much
carbon monoxide and less than 8% as much as the other pollutants that create
smog (such as volatile organic compounds and nitrogen oxides). Scientists estimate that public transportation already reduces emissions of carbon dioxide, which contributes to global
climate change, by over 7.4 million tons annually. If Americans were to use public transportation at equivalent rates as Europeans, scientists estimate that U.S. dependence on imported oil would decrease by more than 40% and that carbon dioxide emissions would be reduced by more than 25%.
Household use of private vehicles accounted for 23% of all UK greenhouse gas emissions in 2005 (excluding international naviagation and aviation), up from 15% in 1990.
Social Inclusion
A important social role played by public transport is ensure that all members of society are able to travel, not just those with a driving licence and access to a vehicle.
Transit-for-all is the name given to a USA movement arguing greater investment in public transportation. Advocates of transit-for-all initiatives argue that the approximately 70 billion dollars currently assigned to subsidizing cheap oil should be reinvested in public transportation. Supporters of transit-for-all initiatives claim there are three main benefits to such a strategic realignment of resources: first, it will benefit the environment and, therefore, the nation’s health; second, it will increase the
economic mobility of citizens currently marginalized because of their geographic isolation and revitalize neighborhoods by reconnecting them to their surroundings; third, it will decrease American dependence on
foreign oil, thereby improving U.S.
national security.
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 public transport systems alleviate this, but reducing car traffic is not always assured.
Some city councils fund public transport infrastructure 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.
Some government officials believe that use of taxpayer capital to fund mass transit will ultimately save taxpayer money in other ways, and therefore, state-funded mass transit is a benefit to the taxpayer. Since lack of mass transit results in more traffic, pollution, and road construction to accommodate more vehicles, all costly to taxpayers, providing mass transit will therefore alleviate these costs.
Another reason for subsidies for public transit are the provision of mobility to those who reject its use on convenience, environmental or safety grounds and those who cannot afford or are physically or legally incapable of using an automobile.
