Bus
A bus (contracted from omnibus, with variants multibus, motorbus, autobus, etc.) is a motor vehicle that carries significantly more passengers than an average car or van, but fewer than the average rail transport. It is most commonly used in public transport, but is also in use for charter#Other usages, charter purposes, or through private ownership. Although the average bus carries between 30 and 100 passengers, some buses have a capacity of up to 300 passengers. The most common type is the single-deck bus, single-deck rigid bus, with double-decker bus, double-decker and articulated buses carrying larger loads, and midibuses and minibuses carrying smaller loads. coach (vehicle), Coaches are used for longer-distance services. Many types of buses, such as city transit buses and inter-city coaches, charge a fare. Other types, such as elementary or secondary school buses or shuttle buses within a post-secondary education campus, are free. In many jurisdictions, bus drivers requir ...

School Transport
Student transport is the transporting of children and teenagers to and from schools and school events. School transport can be undertaken by school students themselves (on foot, bicycle or perhaps Equestrianism, horseback; or for older students, by car), they may be accompanied by family members or caregivers, or the transport may be organised collectively, using school buses or taxicab, taxis. Transport modes General public transport Using the general-purpose public transport is the most common means of student transport, in some countries. Some countries such as Australia have special routes and timetables exclusively used by students, but still run by public transportation services. Sometimes the parents or the students get reimbursed when they buy public transport tickets. School bus Student transport can use specially designed school buses. Many districts in Canada and the United States use specially built and equipped school buses, painted school bus yellow and equippe ...

Hybrid Electric Bus
A hybrid electric bus is a bus that combines a conventional internal combustion engine propulsion system with an electric propulsion system. These types of buses normally use a diesel–electric powertrain and are also known as hybrid diesel–electric buses. The introduction of hybrid electric vehicles and other green vehicles for purposes of public transport forms a part of sustainable transport schemes. Powertrain Types of hybrid vehicle drivetrain A hybrid electric bus may have either a parallel powertrain (e.g., Volvo B5LH) or a series powertrain (e.g., some versions of the Alexander Dennis Enviro400 MMC). Since 2003, Allison Transmission has produced dual-mode hybrid drive units which take the place of a conventional transmission, mostly for transit buses in North America; as the name implies, it is able to switch between series and parallel modes. Plug-in hybrid A plug-in hybrid school bus effort began in 2003 in Raleigh, NC, when Advanced Energy began ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Double-decker Bus
A double-decker bus is a bus that has two storeys or decks. Double-deckers are used primarily for commuter transport, but open-top models are used as sightseeing buses for tourists, and there are coaches too for long-distance travel. They appear in many places around the world but are presently most commonly used as mass transport in cities of Britain, and in Ireland, China, Hong Kong, Berlin and Singapore. The earliest double-decker horse-drawn omnibus appeared in Paris in 1853 and such vehicles were motorised in the 1900s. Double-decker buses were popularised in Great Britain at the start of the 20th century and today the best-known example is the red London bus, namely the AEC Routemaster. Double-deckers in urban transport were also in common use in other places, such as major cities of India, but were mostly diminished or phased out by the end of the 20th century. However they remain common in Britain as well as Ireland and Hong Kong, while in Singapore and Dhaka they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commercial Driver's License
A commercial driver's license (CDL) is a driver's license required in the United States to operate large and heavy vehicles (including trucks, buses, and trailers) or a vehicle of any size that transports hazardous materials or more than 15 passengers (including the driver). United States In the United States, the Commercial Motor Vehicle Safety Act of 1986 established minimum requirements that must be met when a state issues a CDL. While recreational vehicles and farm vehicles are exempt from requiring a CDL, federal law allows states to require a CDL for these vehicles. However, such vehicles are federally exempt from having to obtain a CDL. The following types of CDL licenses are: *Class A – Any combination of vehicles that has a gross combination weight rating or gross combination weight of 26,001 pounds (11,794 kilograms) or more inclusive of a towed unit(s) with a gross vehicle weight rating or gross vehicle weight of more than 10,000 pounds (4,536 kilograms). *Cla ...

Electric Bus
An electric bus is a bus that is propelled using electric motors, as opposed to a conventional internal combustion engine. Electric buses can store the needed electrical energy on board, or be fed mains electricity continuously from an external source such as overhead lines. The majority of buses using on-board energy storage are battery electric buses (which is what this article mostly deals with), where the electric motor obtains energy from an electric vehicle battery, onboard battery pack, although examples of other storage modes do exist, such as the gyrobus that uses flywheel energy storage. When electricity is not stored on board, it is supplied by contact with outside power supplies, for example, via a current collector (like the trolley pole, overhead conduction poles in trolleybuses), or with a ground-level power supply, or through Inductive charging#Dynamic charging, inductive charging. As of 2017, 99% of all battery electric buses in the world have been deployed in M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuel Cell Bus
A fuel cell bus is a bus that uses a hydrogen fuel cell as its power source for Electric motor, electrically driven wheels, sometimes augmented in a Hybrid power, hybrid fashion with batteries or a supercapacitor. The only emission from the bus is water. Several cities around the world have trialled and tested fuel cell buses, with over 5,600 buses in use worldwide, the majority of which are in China. Background Owing to the greenhouse gas emissions and particulate pollution produced by diesel buses, transport operators have been moving towards greener and cleaner buses (such as hybrid electric buses and battery electric buses) since the early 2000s. However, battery electric buses lack range compared to diesel buses, take time to charge and have reduced energy storage in cold weather. Transport operators have therefore evaluated alternatives such as hydrogen fuel cell buses. fuel cell, Hydrogen fuel cells generate electricity by reacting hydrogen and oxygen in the presence of a c ...

Internal Combustion Engine
An internal combustion engine (ICE or IC engine) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine. The force is typically applied to pistons (reciprocating engine, piston engine), turbine blades (gas turbine), a Wankel engine, rotor (Wankel engine), or a propulsive nozzle, nozzle (jet engine). This force moves the component over a distance. This process transforms chemical energy into kinetic energy which is used to propel, move or power whatever the engine is attached to. The first commercially successful internal combustion engines were invented in the mid-19th century. The first modern internal combustion engine, the Otto engine, was designed in 1876 by the German engineer Nicolaus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trolleybus
A trolleybus (also known as trolley bus, trolley coach, trackless trolley, trackless tramin the 1910s and 1920sJoyce, J.; King, J. S.; and Newman, A. G. (1986). ''British Trolleybus Systems'', pp. 9, 12. London: Ian Allan Publishing. .or trolleyDunbar, Charles S. (1967). ''Buses, Trolleys & Trams''. Paul Hamlyn Ltd. (UK). Republished 2004 with or 9780753709702.) is an electric bus that draws power from dual overhead wires (generally suspended from roadside posts) using spring-loaded or pneumatically raised trolley poles. Overhead line#Parallel overhead lines, Two wires, and two trolley poles, are required to complete the electrical circuit. This differs from a tram or streetcar, which normally uses the track as the return path, needing only one wire and one pole (or pantograph (transport), pantograph). They are also distinct from other kinds of Battery electric bus, electric buses, which usually rely on Automotive battery, batteries. Power is most commonly supplied as 600-volt ...

Steam Bus
A steam bus is a bus powered by a steam engine. Early steam-powered vehicles designed for carrying passengers were more usually known as steam carriages, although this term was sometimes used to describe other early experimental vehicles too. History 1830-1895 Regular intercity bus services by steam-powered buses were pioneered in England in the 1830s by associates of Goldsworthy Gurney, Sir Goldsworthy Gurney and by Walter Hancock among others, running reliable services over road conditions which were too hazardous for horse-drawn transportation. Steam carriages were much less likely to overturn, and did not "run away with" the customer as horses sometimes did. They travelled faster than horse-drawn carriages ( over and an average of over longer distances). They could run at a half to a third of the cost of horse-drawn carriages. Their brakes did not lock and drag like horse-drawn transport (a phenomenon that increased damage to roads). According to engineers, steam carri ...

Horsebus
A horse-bus or horse-drawn omnibus was a large, enclosed, and sprung horse-drawn vehicle used for passenger transport before the introduction of motor vehicles. It was widely used in the 19th century in the United States, Europe, and other nations where horse-drawn transport was used and was one of the most common means of public transportation in cities. In a typical arrangement, two wooden benches along the sides of the passenger cabin held sitting passengers facing each other. The driver sat on a separate, front-facing bench, typically in an elevated position outside the passengers' enclosed cabin. In the main age of horse buses, many of them were double-decker buses. On the upper deck, which was uncovered, the longitudinal benches were arranged back to back. Similar, if smaller, vehicles were often maintained at country houses (and by some hotels and railway companies) to convey servants and luggage to and from railway stations. Especially popular around 1870–1900, thes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Political Campaign
A political campaign is an organized effort which seeks to influence the decision making progress within a specific group. In democracy, democracies, political campaigns often refer to election, electoral campaigns, by which representatives are chosen or referendums are decided. In modern politics, the most high-profile political campaigns are focused on general elections and candidates for head of state or head of government, often a President (government title), president or prime minister. Campaign message The message of the campaign contains the ideas that the candidate wants to share with the voters. It is to get those who agree with their ideas to support them when running for a political position. The message often consists of several talking points about policy issues. The points summarize the main ideas of the campaign and are repeated frequently in order to create a lasting impression with the voters. In many elections, the opposition party will try to get the cand ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
