Bus Bay
A bus (contracted from omnibus, with variants multibus, motorbus, autobus, etc.) is a road vehicle that carries significantly more passengers than an average car or van. It is most commonly used in public transport, but is also in use for 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 rigid bus, with double-decker and articulated buses carrying larger loads, and midibuses and minibuses carrying smaller loads. 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 require a special large vehicle licence above and beyond a regular driving licence. Buses may be used for scheduled ...

Driving Licence
A driver's license is a legal authorization, or the official document confirming such an authorization, for a specific individual to operate one or more types of motorized vehicles—such as motorcycles, cars, trucks, or buses—on a public road. Such licenses are often plastic and the size of a credit card. In most international agreements the wording "driving permit" is used, for instance in the Vienna Convention on Road Traffic. In this article's country specific sections, the local spelling variant is used. Most American jurisdictions issue a permit with "driver license" printed on it but some use "driver's license", which is conversational American English. Canadian English uses both "driver's licence" as well as "driver licence" ( Atlantic Canada). The Australian and New Zealand English equivalent is "driver licence". In British English and in many former British colonies it is "driving licence". The laws relating to the licensing of drivers vary between jurisdi ...

Compressed Natural Gas
Compressed natural gas (CNG) is a fuel gas mainly composed of methane (CH4), compressed to less than 1% of the volume it occupies at standard atmospheric pressure. It is stored and distributed in hard containers at a pressure of , usually in cylindrical or spherical shapes. CNG is used in traditional petrol/internal combustion engine vehicles that have been modified, or in vehicles specifically manufactured for CNG use: either alone (dedicated), with a segregated liquid fuel system to extend range (dual fuel), or in conjunction with another fuel ( bi-fuel). It can be used in place of petrol (gasoline), diesel fuel, and liquefied petroleum gas (LPG). CNG combustion produces fewer undesirable gases than the aforementioned fuels. In comparison to other fuels, natural gas poses less of a threat in the event of a spill, because it is lighter than air and disperses quickly when released. Biomethane – refined biogas from anaerobic digestion or landfills – can be used. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Bus
An electric bus is a bus that is propelled using electric motors as opposed to an internal combustion engine. Electric buses can store the needed electricity on-board, or be fed continuously from an external source. The majority of buses storing electricity are battery electric buses (which 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 which uses flywheel energy storage. When electricity is not stored on board, it is supplied by contact with outside power sources. For example, overhead wires as in the trolleybus, or with a ground-level power supply, or through Inductive charging#Dynamic charging, inductive charging. As of 2019, 99% of all battery electric buses in the world have been deployed in Mainland China, with more than 421,000 buses on the road, which is 17% of China's total bus fleet. For comparison, the United Sta ... [...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 electrically driven wheels, sometimes augmented in a 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. Hydrogen fuel cells generate electricity by reacting hydrogen and oxygen in the presence of a catalyst, the by-product of which is ...

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 type 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). Plug-in hybrid A plug-in hybrid school bus effort began in 2003 in Raleigh, NC when Advanced Energy began working between districts across the country and manufacturers to understand the needs of both. The effort demonstrated both a technical and business feasibility and as a result was able to secure funding in 2005 froNASEOto purchase up to 20 buses. The resulting R ...
