Transport or transportation is the movement of people and goods from one location to Transport is performed by various modes, such as air, rail, road, water, cable, pipeline and The field can be divided into infrastructure, vehicles, and Infrastructure consists of the fixed installations necessary for transport, and may be roads, railways, airways, waterways, canals and pipelines, and terminals such as airports, railway stations, bus stations, wharehouses, trucking terminals, refueling depots (including fueling docks and fuel stations) and Terminals may both be used for interchange of passengers and cargo, and for Vehicles traveling on these networks include vehicles of appropriate types such as automobiles, bicycles, buses, trains, trucks people, helocopters and Operations deal with the way the vehicles are operated, and the procedures set for this purpose including financing, legalities and In the transport industry, operations and ownership of infrastructure can be either public or private, depending on the country and Passenger transport may be public, where operators provide scheduled services, or Freight transport has become focused on containerization, although bulk transport is used for large volumes of durable Transport plays an important part in economic growth and globalization, but has a deteriorizing impact on the While it is heavily subsidized by governments, good planning of transport is essential to make traffic flow, and restrain urban Mode Main article: Mode of transport A mode of transport is a technological solution that used a fundamentally different vehicle, infrastructure and The transport of a person or cargo may be by one or more modes, the latter called intermodal Each mode has its advantages and disadvantages, and will be chosen for a trip depended on the nature of the purpose, cargo and While there transport in air and on water has their own mode, land transport has several Human-powered transport remains common in developing countries [edit] Human-powered Main article: Human-powered transport Human-powered transport is the transport of person(s) and/or goods using human muscle- Like animal-powered transport, human-powered transport has existed since time immemorial in the form of walking, running and Modern technology has allowed machines to enhance human- Many forms of human-powered transport remain popular for reasons of cost-saving, leisure, physical exercise and Human-powered transport is sometimes the only type available, especially in underdeveloped or inaccessible It is considered an ideal form of sustainable Although humans are able to walk without infrastructure, the transport can be enhanced through the use of roads, especially when enforcing the human power with vehicles, such as bicycles and inline Human-powered vehicles have also been developed for highly encumbering environments, such as snow and water, by watercraft rowings and skiing; even the air can be entered with human-powered [edit] Animal-powered Main article: Animal-powered transport Animal-powered transport is the use of working animals for the movement of people and Humans may ride some of the animals directly, use them as pack animals for carrying goods, or harness them, alone or in teams, to pull sleds or wheeled Animals are superior to people in their speed, endurance and carrying capacity; prior to the Industrial Revolution they were used for all land transport impracticable for people, and they remain an important mode of transport in less developed areas of the [edit] Air Main article: Aviation Scandinavian Airlines System MD-80 airliner at Kiruna Airport, SwedenA fixed-wing aircraft, commonly called airplane, is a heavier-than-air craft where movement of the air in relation to the wings is used to generate The term is used to distinguish from rotary-wing aircraft, where the movement of the lift surfaces relative to the air generates A gyroplane is both fixed-wing and rotary- Fixed-wing aircraft range from small trainers and recreational aircraft to large airliners and military cargo Two necessities for aircraft are air flow over the wings for lift, and an area for The majority of aircraft also need an airport with the infrastructure to receive maintenance, restocking, refueling and for the loading and unloading of crew, cargo and While the vast majority of aircraft land and take off on land, some are capable of take off and landing on ice, snow and calm The aircraft is the second fastest method of transport, after the Commercial jets can reach up to 875 kilometres per hour (544 mph), single-engine aircraft 175 kilometres per hour (109 mph) Aviation is able to quickly transport people and limited amounts of cargo over longer distances, but incur high costs and energy use; for short distances or in inaccessible places helicopters can be [1] InterCityExpress, a German high-speed passenger train [edit] Rail Main article: Rail transport Rail transport is where train runs along a two parallel steel rails, known as a railway or They rails are anchored perpendicular to ties (or sleepers) of timber, concrete or steel, to maintain a consistent distance apart, or The rails and perpendicular beams are placed on a foundation made of concrete, or compressed earth and gravel in a bed of Alternative methods include monorail and A train consists of one or more connected vehicle that run on the Propulsion is commonly provided by a locomotive, that hauls a series of unpowered cars, that can carry passengers or The locomotive can be powered by steam, diesel or by electricity supplied by a trackside Alternatively, some or all the cars can be powered, known as a multiple Also, a train can be powered by horses, cables, gravity, pneumatics and gas Railed vehicles move with much less friction than rubber tires on paved roads, making trains more energy efficient, though not as efficient as Intercity trains are long-haul services connecting cities;[2] modern high-speed rail is capable of speeds up to 350 km/h (220 mph), but this requires specially-built Regional and commuter trains feed cities from suburbs and surrounding areas, while intra-urban transport is performed by high-capacity tramways and rapid transits, often making up the backbone of a city's public Freight trains traditionally used box cars, requiring manual loading and unloading of the Since the 1960s, container trains have become the dominentsolution for general freight, while large quantities of bulk are transported by dedicated [edit] Road Main article: Road transport Interstate 80 near Berkeley, United StatesA road is an identifiable route, way or path between two or more [3] Roads are typically smoothed, paved, or otherwise prepared to allow easy travel;[4] though they need not be, and historically many roads were simply recognizable routes without any formal construction or [5] In urban areas, roads may pass through a city or village and be named as streets, serving a dual function as urban space easement and [6] The most common road vehicle is the automobile; a wheeled passenger vehicle that carries its own Other users of roads include buses, trucks, motorcycles, bicycles and As of 2002, there were 590 million automobiles Automobiles offer high flexibility and with low capacity, but are deemed with high energy and area use, and the main source of noise and air pollution in cities; buses allow for more efficient travel at the cost of reduced [7] Road transport by truck is often the initial and final stage of freight [edit] Water Main article: Ship transport Automobile ferry in CroatiaWater transport is the process of transport a watercraft, such as a barge, boat, ship or sailboat, over a body of water, such as a sea, ocean, lake, canal or The need for buoyancy unites watercraft, and makes the hull a dominant aspect of its construction, maintenance and In the 1800s the first steam ships were developed, using a steam engine to drive a paddle wheel or propeller to move the The steam was produced using wood or Now most ships have an engine using a slightly refined type of petroleum called bunker Some specialized ships, such as submarines, use nuclear power to produce the Recreational or educational craft still use wind power, while some smaller craft use internal combustion engines to drive one or more propellers, or in the case of jet boats, an inboard water In shallow draft areas, hovercraft are propelled by large pusher-prop Although slow, modern sea transport is a highly effective method of transporting large quantities of non-perishable Transport by water is significantly less costly than air transport for trans-continental shipping;[8] short sea shipping and ferries remain viable in coastal [9][10] Trans-Alaska Pipeline for crude oil [edit] Other Pipeline transport sends goods through a pipe, most commonly liquid and gases are sent, but pneumatic tubes can send solid capsules using compressed Any chemically stable liquid or gas can be sent through a Short-distance systems exist for sewage, slurry, water and beer, while long-distance networks are used for petroleum and natural Cable transport is a broad mode where vehicles are pulled by cables instead of an internal power It is most commonly used at steep Typical solutions include aerial tramway, elevators, escalator and ski lifts; some of these are also categorized as conveyor Spaceflight is transport out of Earth's atmosphere into outer space by means of a While large amounts of research have gone into technology, it is rarely used except to put satellites into orbit, and conduct scientific However, man has landed on the moon, and probes have been send to all the planets of the Solar S [edit] Elements Bridges, such as Golden Gate Bridge, allow roads and railways to cross bodies of water [edit] Infrastructure Main article: Infrastructure Infrastructure is the fixed installations that allow a vehicle to It consists of both a way, terminal and facilities for parking and For rail, pipeline, road and cable transport, the entire way the vehicle travels must be built Air and water craft are able to avoid this, since the airway and seaway do not need to be built However, they require fixed infrastructure at Terminals such as airports, ports and stations, are locations were passengers and freight can be transferred from one vehicle or mode to For passenger transport, terminals are integrating different modes to allow riders to interchange to take advantage of each mode's For instance, airport rail links connect airports to the city centers and The terminals for automobiles are parking lots, while buses and coaches can operates from simple [11] For freight, terminals act as transshipment points, though some cargo is transported directly from the point of production to the point of The financing of infrastructure can either be public or Transport is often a natural monopoly and a necessity for the public; roads, and in some countries railways and airports are funded through New infrastructure projects can involve large spendings, and are often financed through Many infrastructure owners therefore impose usage fees, such as landing fees at airports, or toll plazas on Independent of this, authorities may impose taxes on the purchase or use of A Peugeot 206 participating in the World Rally Championship [edit] Vehicles Main article: Vehicle A vehicle is any non-living device that is used to move people and Unlike the infrastructure, the vehicle moves along with the cargo and Vehicles that do not operate on land, are usually called Unless being pulled by a cable or muscle-power, the vehicle must provide its own propulsion; this is most commonly done through a steam engine, combustion engine, electric motor, a jet engine or a rocket, though other means of propulsion also Vehicles also need a system of converting the energy into movement; this is most commonly done through wheels, propellers and Vehicles are most commonly staffed by a However, some systems, such as people movers and some rapid transits, are fully For passenger transport, the vehicle must have a compartment for the Simple vehicles, such as automobiles, bicycles or simple aircraft, may have one of the passengers as a [edit] Operation Incheon International Airport, South KoreaPrivate transport is only subject to the owner of the vehicle, who operates the vehicle For public transport and freight transport, operations are done through private enterprise or by The infrastructure and vehicles may be owned and operated by the same company, or they may be operated by different Traditionally, many countries have had a national airline and national Since the 1980s, many of these have been International shipping remains a highly competitive industry with little regulation,[12] but ports can be public [13] [edit] Function Relocation of travelers and cargo are the most common uses of However, other uses exist, such as the strategic and tactical relocation of armed forces during warfare, or the civilian mobility construction or emergency Chhatrapati Shivaji Terminus in Mumbai, India [edit] Passenger Main article: Travel Passenger transport, or travel, is divided into public and private Public is scheduled services on fixed routes, while private is vehicles that provide ad hoc services at the riders The latter offers better flexibility, but has lower capacity, and a higher environmental Travel may be as part of daily commuting, for business, leisure or Short-haul transport is dominated by the automobile and mass The latter consists of buses in rural and small cities, supplemented with commuter rail, trams and rapid transit in larger Long-haul transport involves the use of the automobile, trains, coaches and aircraft, the last of which have become predominantly used for the longest, including intercontinental, Intermodal passenger transport is where a journey is performed through the use of several modes of transport; since all human transport normally starts and ends with walking, all passenger transport can be considered Public transport may also involve the intermediate change of vehicle, within or across modes, at a transport hub, such as a bus or railway International travel may be restricted for some individuals due to legislation and visa [edit] Freight Main article: Shipping Freight transport, or shipping, is a key in the value chain in [14] With increased specialization and globalization, production is being located further away from consumption, rapidly increasing the demand for [15] While all modes of transport are used for cargo transport, there is high differentiation between the nature of the cargo transport, in which mode is [16] Logistics refers to the entire process of transferring products from producer to consumer, including storage, transport, transshipment, warehousing, material-handling and packaging, with associated exchange of [17] Incoterm deals with the handling of payment and responsibility of risk during [18] Freight train with containers in the United KingdomContainerization, with the standardization of ISO containers on all vehicles and at all ports, has revolutionized international and domestic trade, offering huge reduction in transshipment Traditionally, all cargo had to be manually loaded and unloaded into the haul of any ship or car; containerization allows for automated handling and transfer between modes, and the standardized sizes allow for gains in economy of scale in vehicle This has been one of the key driving factors in international trade and globalization since the [19] Bulk transport is common with cargo that can be handled roughly without deterioration; typical examples are ore, coal, cereals and Because of the uniformity of the product, mechanical handling can allow enormous quantities to be handled quickly and The low value of the cargo combined with high volume also means that economies of scale become essential in transport, and gigantic ships and whole trains are commonly used to transport Liquid products with sufficient volume may also be transported by Air freight has become more common for products of high value; while less than one percent of world transport by volume is by airline, it amounts to forty percent of the Time has become especially important in regards to principles such as postponement and just-in-time within the value chain, resulting in a high willingness to pay for quick delivery of key components or items of high value-to-weight [20] In addition to mail, common items send by air include electronics and fashion [edit] History Main article: History of transport Bullock team hauling wool in AustraliaHumans first means of transport was walking and The domestication of animals introduces a new way to lay the burden of transport on more powerful creatures, allowing heavier loads to be hauled, or humans to ride the animals for higher speed and Inventions such as the wheel and sled helped make animal transport more efficient through the introduction of Also water transport, including rowed and sailed vessels, dates back to time immemorial, and was the only efficient way to transport large quantities or over large distances prior to the Industrial R The first forms of road transport were horses, oxen or even humans carrying goods over dirt tracks that often followed game Paved roads were first built by the Roman Empire, to allow armies to travel quicky; they built deep roadbeds of crushed stone as an underlying layer to ensure that they kept dry, as the water would flow out from the crushed stone, instead of becoming mud in clay The first watercraft were canoes cut out from tree Early water transport was accomplished with ships that were either rowed or used the wind for propulsion, or a combination of the The importance of water has led to most cities, that grew up as sites for trading, being located on rivers or at sea, ofter at the intersection of two bodies of Until the Industrial Revolution, transport remained slow and costly, and production and consumption were located as close to each other as
