Warsaw Uprising
The Warsaw Uprising ( pl, powstanie warszawskie; german: Warschauer Aufstand) 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 ( pl, Armia Krajowa). 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 temporarily 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 Uprising began on 1 August 1944 as part of a nationwide Operation Tempest, launched at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Safety Barrier
A safety barrier is a component which prevents passage into a dangerous area, commonly used to mitigate risk. Safety barriers may be hard barriers physically restricting passage or soft barriers that control circuits based on the presence of foreign bodies. 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 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 prese ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Braess's Paradox
Braess's paradox is the observation that adding one or more roads to a road network can slow down overall traffic flow through it. The paradox was discovered by 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 optimal self-interested decision as to which route is quickest, a shortcut could be chosen too often for drivers to have the shortest travel times possible. More formally, the idea behind Braess's di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boom Barrier
A boom barrier, also known as a boom gate, is a bar, or pole pivoted to allow the boom to block vehicular or pedestrian access through a controlled point. Typically the tip of a boom gate rises in a vertical arc to a near vertical position. Boom gates are often counterweighted, so the pole is easily tipped. Boom gates are often paired either end to end, or offset appropriately to block traffic in both directions. Some boom gates also have a second arm which hangs 300 to 400 mm below the upper arm when lowered, to increase approach visibility, and which hangs on links so it lies flat with the main boom 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'' when raised. Automatic boom barrier There are various technologies for an automatic boom barrier. One of them is electro-mechanical, which is widely used due to its reliability. The o ...

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 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 produced around the world. They were first produced in the U.S. 40 years ago by Friedrichs Mfg for New Orleans's Mardi Gras para ...

Road Traffic Control
: ''For the road traffic science, see various articles under 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 (TCT's) or Traffic Control Supervisors (TCS's) are often known as "lollipop men" (usually this name only applies to TCT's 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 struck by passing vehic ...

Extinction Rebellion
Extinction Rebellion (abbreviated as XR) is a 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 social and ecological collapse. Extinction Rebellion was established in the United Kingdom in May 2018 by Gail Bradbrook, Simon Bramwell, and Roger Hallam, along with eight 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 London: Piccadilly Circus, Oxford Circus, Marble Ar ...

Traffic
Traffic comprises pedestrians, vehicles, ridden or herded animals, trains, and other conveyances that use public ways (roads) for travel and transportation. 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. Traffic is formally organized in many jurisdictions, with marked lanes, junctions, intersections, interchanges, traffic signals, 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 drivers' common sense and willingness to cooperate. Organization ...
