Dual-mode Vehicle
A dual-mode vehicle (DMV) is a vehicle that can operate on conventional road surfaces as well as a railway track or a dedicated track known as a "guideway". The development of these vehicles started together with personal rapid transport systems in 1950s or even earlier. Dual-mode vehicles are commonly electrically powered and run in dual-mode for power too, using batteries for short distances and low speeds, and track-fed power for longer distances and higher speeds. Dual-mode vehicles were originally studied as a way to make electric cars suitable for inter-city travel without the need for a separate engine. Dual-mode transit describes transportation systems in which dual-mode vehicles operate on both public roads and on a guideway; thus using two modes of transport. In a typical dual-mode transit system, private vehicles comparable to automobiles would be able to travel under driver control on the street, but then enter a guideway, which may be a specialized form of railway o ...

Tram
A tram (called a streetcar or trolley in North America) is a rail vehicle that travels on tramway tracks on public urban streets; some include segments on segregated right-of-way. The tramlines or networks operated as public transport are called tramways or simply trams/streetcars. Many recently built tramways use the contemporary term light rail. The vehicles are called streetcars or trolleys (not to be confused with trolleybus) in North America and trams or tramcars elsewhere. The first two terms are often used interchangeably in the United States, with ''trolley'' being the preferred term in the eastern US and ''streetcar'' in the western US. ''Streetcar'' or ''tramway'' are preferred in Canada. In parts of the United States, internally powered buses made to resemble a streetcar are often referred to as "trolleys". To avoid further confusion with trolley buses, the American Public Transportation Association (APTA) refers to them as "trolley-replica buses". In the Unit ...

Electro-diesel Locomotive
An electro-diesel locomotive (also referred to as a dual-mode or bi-mode locomotive) is a type of locomotive that can be powered either from an electricity supply (like an electric locomotive) or by using the onboard diesel engine (like a diesel-electric locomotive). For the most part, these locomotives are built to serve regional, niche markets with a very specific purpose. Overview Electro-diesel locomotives are used to provide continuous journeys along routes that are only partly electrified without a change of locomotive, avoid extensive running of ''diesel under the wires'' (using a diesel locomotive where electrified lines are available), and giving solution where diesel engines are banned. They may be designed or adapted mainly for electric use, mainly for diesel use or to work well as either electric or diesel. Note that, as well as the electric multiple unit (EMU) and diesel multiple unit (DMU), where no discrete locomotive is present, an electro-diesel (bi-mode) ...

Electric Vehicle Battery
An electric vehicle battery (EVB, also known as a traction battery) is a rechargeable battery used to power the electric motors of a battery electric vehicle (BEV) or hybrid electric vehicle (HEV). Typically lithium-ion batteries, they are specifically designed for high electric charge (or energy) capacity. Electric vehicle batteries differ from starting, lighting, and ignition (SLI) batteries as they are designed to give power over sustained periods of time and are deep-cycle batteries. Batteries for electric vehicles are characterized by their relatively high power-to-weight ratio, specific energy and energy density; smaller, lighter batteries are desirable because they reduce the weight of the vehicle and therefore improve its performance. Compared to liquid fuels, most current battery technologies have much lower specific energy, and this often impacts the maximum all-electric range of the vehicles. The most common battery type in modern electric vehicles are lithium-ion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dual-mode Bus
A dual-mode bus is a bus that can run independently on power from two different sources, typically electricity from overhead lines like a trolleybus or from batteries like a hybrid bus, alternated with conventional fossil fuel (generally diesel fuel). In contrast to other hybrid buses, dual-mode buses can run forever exclusively on their electric power source (wires). Several of the examples listed below involve the use of dual-mode buses to travel through a tunnel on electric overhead power. Many modern trolleybuses are equipped with auxiliary propulsion systems, either using a small diesel engine or battery power, allowing movement away from the overhead wires, called "off-wire" movement, but such vehicles are generally not considered to be dual-mode buses if their off-wire capability is very limited. Examples include the fleet of about 300 trolleybuses in San Francisco and the trolleybuses used on a 2005-opened system in Rome, Italy,Webb, Mary (ed.) (2009). ''Jane's Urban Tra ...

Alden StaRRcar
The Alden staRRcar, short for "Self-Transport Road and Rail Car", was a personal rapid transit (PRT) system designed by William Alden in the 1960s. It originally envisioned small electrically powered cars suitable for short distance trips at low speed within urban areas, which could optionally merge onto tracks that would provide power and guidance for high-speed travel over longer inter-city distances. It was one of the earliest ''dual-mode'' vehicles to be proposed, and one of the earliest to be actually built. Over its lifetime the design changed dramatically, originally a four-person vehicle with dual-mode operation but eventually emerging as a much larger people mover for 20 people. In this form, Boeing Vertol was awarded a construction contract in 1970 to build a demonstration system in Morgantown, West Virginia. A smaller system was also built by their licensee, Kobe Steel, and installed at the Expo '75 on Okinawa (as well as the more advanced CVS). The Morgantown Persona ...

Last Mile (transportation)
Last mile in supply chain management and transportation planning is the last leg of a journey comprising the movement of people and goods from a transportation hub to a final destination. "Last mile" was adopted from the telecommunications industry which faced difficulty connecting individual homes to the main telecommunications network. Similarly, in supply chain management last-mile describes the difficult last part in the transportation of people and packages from hubs to final destinations. Last-mile delivery is an increasingly studied field as the number of business-to-consumer (b2c) deliveries grow especially from e-commerce companies in freight transportation, and ride-sharing companies in personal transportation. Some challenges of last-mile delivery include minimizing cost, ensuring transparency, increasing efficiency, and improving infrastructure. History "Last mile" was originally used in the telecommunications industry to describe the difficulty of connecting end u ...

Atmospheric Particulate Matter
Particulates – also known as atmospheric aerosol particles, atmospheric particulate matter, particulate matter (PM) or suspended particulate matter (SPM) – are microscopic particles of solid or liquid matter suspended in the air. The term '' aerosol'' commonly refers to the particulate/air mixture, as opposed to the particulate matter alone. Sources of particulate matter can be natural or anthropogenic. They have impacts on climate and precipitation that adversely affect human health, in ways additional to direct inhalation. Types of atmospheric particles include suspended particulate matter; thoracic and respirable particles; inhalable coarse particles, designated PM, which are coarse particles with a diameter of 10 micrometers (μm) or less; fine particles, designated PM, with a diameter of 2.5 μm or less; ultrafine particles, with a diameter of 100 nm or less; and soot. The IARC and WHO designate airborne particulates as a Group 1 carcinogen. Particula ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Asatō Line
The is a Japanese railway line connecting Kaifu Station, Kaiyō, Tokushima, Kaiyō and Kannoura Station, Tōyō, Kōchi, Tōyō. Together with Shikoku Railway Company, JR Shikoku's Mugi Line, it has the official nickname . This is the only railway line operated by . The company's name is abbreviated to the portmandeau . Since the line goes through a relatively sparsely populated area, it is under severe business stress, to the point where closure of the line has been proposed. The railway company commenced operating road–rail vehicles, known as DMV (Dual-mode transit, dual-mode vehicle) in Japan, on the Asato Line from 25 December 2021. The vehicles, 3 heavily-modified Toyota Coaster, Toyota Coasters, are claimed to be the first in the world, will allow through service to areas without rail track laid. In preparation, the rail line was disconnected from the Mugi Line since summer 2019. History Japanese National Railways started the construction of the Mugi Line, eastern sectio ...

Personal Rapid Transit
Personal rapid transit (PRT), also referred to as podcars or guided/railed taxis, is a public transport mode featuring small low-capacity automated vehicles operating on a network of specially built guideways. PRT is a type of automated guideway transit (AGT), a class of system which also includes larger vehicles all the way to small subway systems. In terms of routing, it tends towards personal public transport systems. PRT vehicles are sized for individual or small group travel, typically carrying no more than three to six passengers per vehicle. Guideways are arranged in a network topology, with all stations located on sidings, and with frequent merge/diverge points. This allows for nonstop, point-to-point travel, bypassing all intermediate stations. The point-to-point service has been compared to a taxi or a horizontal lift (elevator). Numerous PRT systems have been proposed but most have not been implemented. , only a handful of PRT systems are operational: Morgantown Per ...
