GLPS
Ground-level power supply, also known as surface current collection or, in French, ''alimentation par le sol'' ("feeding via the ground"), is a concept and group of technologies that enable electric vehicles to collect electric power at ground level instead of the more common overhead lines. Ground-level power supply systems date to the beginning of electric tramways. Often they were implemented where the public expressed an aesthetic desire to avoid overhead lines. Some of the earliest systems used conduit current collection. Systems in the 21st century, such as Alstom APS, Ansaldo Tramwave, CAF ACR, and Elways, were developed to modern standards of safety and reliability, and added the ability to supply power to electric buses, trucks, and cars. Some ground-level power supply systems use efficient, energy-dense capacitors and batteries to power portions of an electric transit system—for example, enabling buses and trains to charge their batteries during station stops. ...

Electric Road
An electric road, eroad, e-roadway, or electric road system (ERS) is a road which supplies electric power to vehicles travelling on it. Common implementations are Overhead line, overhead power lines above the road, ground-level power supply through conductive rails, and dynamic wireless power transfer (DWPT) through Inductive charging#Transportation, resonant inductive coils or inductive cables embedded in the road. Overhead power lines are limited to commercial vehicles while ground-level rails and inductive power transfer can be used by any vehicle, which allows for public charging through a system for power metering and billing. Of the three methods, ground-level conductive rails are estimated to be the most cost-effective. Government studies and trials have been conducted in several countries seeking a national electric road network. South Korea, Korea was the first to implement an induction-based public electric road with a commercial bus line in 2013 after testing an experime ...

Overhead Line
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, Electric multiple unit, electric multiple units, trolleybuses or trams. The generic term used by the International Union of Railways for the technology is ''overhead line''. It is known variously as overhead catenary, overhead contact line (OCL), overhead contact system (OCS), overhead equipment (OHE), overhead line equipment (OLE or OHLE), overhead lines (OHL), overhead wiring (OHW), traction wire, and trolley wire. An overhead line consists of one or more wires (or Overhead conductor rail, rails, particularly in tunnels) situated over rail tracks, raised to a high electrical potential by connection to feeder stations at regularly spaced intervals along the track. The feeder stations are usually fed from a High voltage, high-voltage Electricity distribution, electrical grid. Overview Electric trains that collect their current from overhead lines use a de ...

Minnesota Department Of Transportation
The Minnesota Department of Transportation (MnDOT, ) oversees Transportation in Minnesota, transportation by all modes including land, water, air, rail, walking and bicycling in the U.S. state of Minnesota. The Cabinet (government), cabinet-level agency is responsible for maintaining the state's trunk highway system (including List of Minnesota state highways, state highways, U.S. Highways, and Interstate Highways), funding municipal airports and maintaining radio navigation aids, and other activities. History The agency's history can be traced to the state's Railroad and Warehouse Commission which emerged slowly from 1871 to 1905, and the State Highway Commission created in 1905. The Highway Commission was abolished in 1917 and replaced by a Department of Highways. The Minnesota Highway Department has been credited with numerous works listed on the U.S. National Register of Historic Places. For air transport, the Minnesota Aeronautics Commission was created in 1933. Much of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transportation Research Board
The Transportation Research Board (TRB) is a division of the National Academies of Sciences, Engineering, and Medicine. TRB's mission is to mobilize expertise, experience, and knowledge to anticipate and solve complex transportation-related challenges. For example, committees, researchers, and staff are currently focused on advancing resilient infrastructure, exploring transformational technology, and caring for the public’s health and safety. It publishes research via four cooperative research programs and through consensus studies, which may be requested by the U.S. Congress. As one of seven major divisions of the National Academies of Sciences, Engineering, and Medicine, TRB research is objective and interdisciplinary. TRB hosts nearly 200 standing technical committees that address specific aspects of transport and the TRB Annual Meeting attracts thousands of transportation professionals. History The Transportation Research Board was established in 1920 as the "National Advis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edinburgh Tram Network
Edinburgh Trams is a tramway in Edinburgh, Scotland, operated by Edinburgh Trams Ltd. It is an line between Newhaven and Edinburgh Airport, with 23 stops. A modern tram network for Edinburgh was proposed by Edinburgh Council in 1999, with detailed design work being performed over the next decade. Construction of the first phase, linking Edinburgh Airport with Newhaven, began in June 2008, but encountered substantial delays and cost overruns. During 2009, a 15-year contract held by Transdev to operate and maintain the tram network was cancelled. By mid-2010, cancellation of the whole project was being publicly considered; during the following year it was announced that the length of the tram network would be drastically curtailed. Prior to August 2011, the project was overseen by Transport Initiatives Edinburgh (TIE), a company wholly owned by Edinburgh Council; TIE was disbanded largely due to its failings on the project's delivery. The troubled construction of the Edinbu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
King Charles Bridge
Charles Bridge ( , ) is a medieval stone arch bridge that crosses the Vltava river in Prague, Czech Republic. Its construction started in 1357 under the auspices of King Charles IV, Holy Roman Emperor, Charles IV, and finished in the early 15th century.; The bridge replaced the old Judith Bridge built 1158–1172 that had been severely damaged by a flood in 1342. This new bridge was originally called Stone Bridge (''Kamenný most'') or Prague Bridge (''Pražský most''), but has been referred to as "Charles Bridge" since 1870. As the only means of crossing the river Vltava until 1841, Charles Bridge was the most important connection between Prague Castle and the city's Old Town, Prague, Old Town and adjacent areas. This land connection made Prague important as a trade route between Eastern and Western Europe. The bridge is located on the historic coronation route of the List of Bohemian monarchs, Bohemian kings. The bridge is long and nearly wide. Following the example of th ...

František Křižík
František Křižík (; 8 July 1847 – 22 January 1941) was a Czech inventor, electrical engineer and entrepreneur. Biography Křižík was born on 8 July 1847 in a poor family in Plánice. His father, a shoemaker, died early. When he was 12, the family moved to Prague, where he began studying, but for financial reasons he did not graduate from the real school. However, due to his significant technical talent, he was still accepted to the Czech Technical University in Prague (ČVUT) in 1866. After completing his studies at the university, Křižík was first employed at the Kaufmann factory for the production of telegraphs and signals as a repairman for telegraph devices. He soon began to make his own discoveries. Křižík is considered the pioneer of practical electrical engineering and in electrification of Bohemia and Austria-Hungary. At the time he was often compared to Thomas Edison. In 1878, Křižík invented a remotely operated signaling device to protect against c ...
