Roadblock (barrier)
A roadblock is a temporary installation set up to control or block traffic along a road. The reasons for one could be: *Roadworks *Temporary road closure during special events *Car chase, Police chase *Robbery *Sobriety checkpoint *Protest, Protests In peaceful circumstances, they are usually installed by the police or road transport authorities; they are also commonly employed during wars and are usually staffed by heavily armed soldiers in that case. During protests and riots, both police and demonstrators sometimes use roadblocks. 1 Glo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Road Block
Campaign for Better Transport is an advocacy group in the United Kingdom that promotes sustainable transport, particularly bus and rail services. It was launched as Transport 2000 in February 1973 by the National Union of Railwaymen with the Railway Industry Association, the Liberal Party Environmental Panel and others. In January 2007 it absorbed the Road Block anti-road building campaign led by Rebecca Lush and campaigned for less expenditure on road building. The organisation changed its name from Transport 2000 to Campaign for Better Transport in September 2007. History Transport 2000 Transport 2000 was launched on 6 February 1973 with a press conference at the Hotel Russell, London. It initially had offices at 30-34 Buckingham Gate, Westminster. The formation of the organisation was a reaction to the newspaper disclosure in October 1972 that one of the options in a report for the Department of the Environment was the possible closure of a large part of the rail netwo ...

Warsaw Uprising
The Warsaw Uprising (; ), sometimes referred to as the August Uprising (), or the Battle of Warsaw, was a major World War II operation by the Polish resistance movement in World War II, Polish underground resistance to liberate Warsaw from German occupation. It occurred in the summer of 1944, and it was led by the Polish resistance Home Army (). The uprising was timed to coincide with the retreat of the German forces from Poland ahead of the Soviet advance. While approaching the eastern suburbs of the city, the Red Army halted combat operations, enabling the Germans to regroup and defeat the Polish resistance and to Planned destruction of Warsaw, destroy the city in retaliation. The Uprising was fought for 63 days with little outside support. It was the single largest military effort taken by any European Resistance during World War II, resistance movement during World War II. The defeat of the uprising and suppression of the Home Army enabled the pro-Soviet Polish administra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Safety Barrier
A safety barrier is a component which prevents passage into a dangerous area, and is commonly used to mitigate risk. Description A safety barrier is a component which prevents passage into a dangerous area. It is commonly used to mitigate risk in the Hazard-Barrier-Target model, as studied in safety science. Work Safe Victoria (an Australian organization) defines a Safety Barrier as a device that: * physically separate the work area and the traveled way, * are designed to resist the penetration of an out-of control vehicle, and * have properties which redirect an out-of-control vehicle back on to the road away from the work area. Types of barriers Hard barriers are fixed or removable guards which prevent entry. These include fences, traffic barriers, and crush barriers. Soft barriers are devices such as light curtains. They detect the presence of a foreign body and are tied into the control circuit to stop the machine. Components Hard barriers are fixed into the ground ...

Illinois V
Illinois ( ) is a state in the Midwestern United States. It borders on Lake Michigan to its northeast, the Mississippi River to its west, and the Wabash and Ohio rivers to its south. Of the fifty U.S. states, Illinois has the fifth-largest gross domestic product (GDP), the sixth-largest population, and the 25th-most land area. Its capital city is Springfield in the center of the state, and the state's largest city is Chicago in the northeast. Present-day Illinois was inhabited by Indigenous cultures for thousands of years. The French were the first Europeans to arrive, settling near the Mississippi and Illinois rivers in the 17th century Illinois Country, as part of their sprawling colony of New France. A century later, the revolutionary war Illinois campaign prefigured American involvement in the region. Following U.S. independence in 1783, which made the Mississippi River the national boundary, American settlers began arriving from Kentucky via the Ohio River. Ill ...

Braess's Paradox
Braess's paradox is the observation that adding one or more roads to a road network can slow down overall road traffic, traffic flow through it. The paradox was first discovered by Arthur Cecil Pigou, Arthur Pigou in 1920, and Stigler's law of eponymy, later named after the German mathematician Dietrich Braess in 1968. The paradox may have analogies in electrical power grids and biological systems. It has been suggested that, in theory, the improvement of a malfunctioning network could be accomplished by removing certain parts of it. The paradox has been used to explain instances of improved traffic flow when existing major roads are closed. Discovery and definition Dietrich Braess, a mathematician at Ruhr University, Germany, noticed the flow in a road network could be impeded by adding a new road, when he was working on traffic modelling. His idea was that if each driver is making the optimization, optimal self-interested decision as to which route is quickest, a shortcut cou ...

Boom Barrier
A bar, post, pole, beam, or boom gate, also known as a boom or a boom barrier, is a beam or bar on a pivot used as a gate. The boom is lowered to block vehicular or pedestrian access through a controlled point or raised to permit such traffic. Typically, the bar has a 90° range of motion with a vertical raised resting position and a horizontal lowered resting position. Bar gates, especially manually operated ones, are often counterweighted to allow easier manual control. Bar gates are frequently paired end to end or closely offset to block traffic in both directions. Some bar gates also have a second arm which hangs 30 to 40 cm below the upper arm when lowered to increase approach visibility. This underbar typically hangs on links, so it lies flat with the main bar as the barrier is raised. Some barriers also feature a pivot roughly half way, where as the barrier is raised, the outermost half remains horizontal, with the barrier resembling an upside-down L (or gamma) when r ...

Barricade
Barricade (from the French ''barrique'' - 'barrel') is any object or structure that creates a barrier or obstacle to control, block passage or force the flow of traffic in the desired direction. Adopted as a military term, a barricade denotes any improvised field fortification, such as on city streets during urban warfare. Barricades also include temporary traffic barricades designed with the goal of dissuading passage into a protected or risk, hazardous area or large slabs of cement whose goal is to prevent forcible passage by a vehicle. Stripes on barricades and panel devices slope downward in the direction traffic must travel. There are also pedestrian barricades - sometimes called bike rack barricades for their resemblance to a now obsolete form of bicycle stand, or police barriers. They originated in France approximately 50 years ago and are now used around the world. They were first used in the U.S. 40 years ago by Friedrichs Mfg for New Orleans's Mardi Gras parades. ...

Road Traffic Control
: ''For the road traffic science, see various articles under :Road traffic management, Road traffic management.'' Road traffic control involves directing vehicular and pedestrian traffic around a construction zone, accident or other road disruption, thus ensuring the safety of emergency response teams, construction workers and the general public. Traffic control also includes the use of CCTV and other means of monitoring traffic by local or state roadways authorities to manage traffic flows and providing advice concerning traffic congestion. Traffic Control Technicians (TCTs) or Traffic Control Supervisors (TCSs) are often known as "lollipop men" (usually this name only applies to TCTs working near schools to aid pupils in road crossing) from the appearance of their ''Stop/Slow'' signs, known as "Stop bats". Overview Road Traffic control is an outdoors occupation, night or day for long hours in all weathers, and is considered a dangerous occupation due to the high risk of being ...

Extinction Rebellion
Extinction Rebellion (abbreviated as XR) is a UK-founded global environmental movement, with the stated aim of using nonviolent civil disobedience to compel government action to avoid tipping points in the climate system, biodiversity loss, and the risk of societal collapse, social and ecological collapse. Extinction Rebellion was established in Stroud in May 2018 by Gail Bradbrook, Simon Bramwell, Roger Hallam (activist), Roger Hallam, Stuart Basden, along with six other co-founders from the campaign group Rising Up! Its first major action was to occupy the London Greenpeace offices on 17 October 2018, which was followed by the public launch at the "Declaration of Rebellion" on 31 October 2018 outside the UK Parliament. Earlier that month, about one hundred academics signed a call to action in their support. In November 2018, five bridges across the River Thames in London were blockaded as a protest. In April 2019, Extinction Rebellion occupied five prominent sites in central Lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hisingen
Hisingen () is the fifth-largest island of Sweden (after Gotland, Öland, Södertörn and Orust), with an area of . It is a river island, formed by the split of the Göta Älv at Bohus Fortress, Bohus, and is defined to the east and south by the main arm of that river, to the north by the smaller arm (known as the Nordre Älv), and to the west by the Kattegat. The southern part of Hisingen is extensively urbanised, representing the northern suburbs of the city of Gothenburg. The island is divided between the Provinces of Sweden, historical provinces of Västergötland and Bohuslän, but lies entirely within the Counties of Sweden, modern county of Västra Götaland County, Västra Götaland.

For a brief, post-war period Hisingen was home to the largest shipbuilding centre in the world, but all thre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
West Bank
The West Bank is located on the western bank of the Jordan River and is the larger of the two Palestinian territories (the other being the Gaza Strip) that make up the State of Palestine. A landlocked territory near the coast of the Mediterranean Sea in the Levant region of West Asia, it is bordered by Jordan and the Dead Sea to the east and by Israel (via the Green Line (Israel), Green Line) to the south, west, and north. Since 1967, the territory has been under Israeli occupation of the West Bank, Israeli occupation, which has been Legality of the Israeli occupation of Palestine, regarded illegal under the law of the international community. The territory first emerged in the wake of the 1948 Arab–Israeli War as a region occupied and subsequently Jordanian annexation of the West Bank, annexed by Jordan. Jordan ruled the territory until the 1967 Six-Day War, when it was occupied by Israel. Since then, Israeli Civil Administration, Israel has administered the West Bank (ex ...

Traffic
Traffic is the movement of vehicles and pedestrians along land routes. Traffic laws govern and regulate traffic, while rules of the road include traffic laws and informal rules that may have developed over time to facilitate the orderly and timely flow of traffic. Organized traffic generally has well-established priorities, lanes, right-of-way, and traffic control at intersections. ( International Regulations for Preventing Collisions at Sea govern the oceans and influence some laws for navigating domestic waters.) Traffic is formally organized in many jurisdictions, with marked lanes, junctions, intersections, interchanges, traffic signals, cones, or signs. Traffic is often classified by type: heavy motor vehicle (e.g., car, truck), other vehicle (e.g., moped, bicycle), and pedestrian. Different classes may share speed limits and easement, or may be segregated. Some jurisdictions may have very detailed and complex rules of the road while others rely more on drive ...
