Roadblock
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 * Police chase *Robbery * Sobriety checkpoint 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 Global Bus. L. Rev. 229 (2010- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sobriety Checkpoint
A random checkpoint is a military and police tactic. In a military context, checkpoints involve the setup of a hasty roadblock by mobile truck- or armored vehicle-mounted infantry to disrupt unauthorized or unwanted movement or military activity and to check for valid identification and search for contraband, fugitives, or weapons that are not permitted in civilian hands. Random checkpoints are set up to achieve surprise, as opposed to known permanently located checkpoints, which suspects could circumvent. They are often established in locations where they cannot be observed by approaching traffic until it is too late to withdraw and escape without being observed. Patrol car-equipped police units regularly use random checkpoints to detect drivers who are suspected of impaired driving. Police also use hastily set up roadblocks to check cars and car trunks when they are pursuing an armed and dangerous fugitive. As with military checkpoints, sobriety checkpoints and fugitive road ...

Traffic Break
A traffic break is any separation in the flow of traffic—naturally occurring or otherwise—along a road or highway. In heavily congested traffic, natural breaks occur rarely, thus the term ''traffic break'' most commonly refers to the manual separation of traffic, normally conducted by highway patrol officers. Most such traffic breaks are used to clear a hazardous obstruction from the road or to allow a stalled vehicle to safely make its way off the road and onto the shoulder. For example, a highway patrol officer may arrive at the site of the accident and then radio to another officer to initiate a traffic break. The second officer enters traffic before the site of the accident, turns on their warning lights, and begins weaving across multiple lanes to signal that other drivers are to slow down and remain behind the officer. The speed to which the officer slows is based on the amount of time needed to clear the accident ahead. An officer may completely stop traffic to yield l ...

West Bank
The West Bank ( ar, الضفة الغربية, translit=aḍ-Ḍiffah al-Ġarbiyyah; he, הגדה המערבית, translit=HaGadah HaMaʽaravit, also referred to by some Israelis as ) is a landlocked territory near the coast of the Mediterranean in Western Asia that forms the main bulk of the Palestinian territories. It is bordered by Jordan and the Dead Sea to the east and by Israel (see Green Line) to the south, west, and north. Under an Israeli military occupation since 1967, its area is split into 165 Palestinian "islands" that are under total or partial civil administration by the Palestinian National Authority (PNA), and 230 Israeli settlements into which Israeli law is "pipelined". The West Bank includes East Jerusalem. It initially emerged as a Jordanian-occupied territory after the 1948 Arab–Israeli War, before being annexed outright by Jordan in 1950, and was given its name during this time based on its location on the western bank of the Jordan River ...

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 A ...

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 pre ... [...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 ...

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

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 vehi ...

Roadworks
Roadworks (called road work or road construction in the United States) occur when part of the road, or in rare cases, the entire road, has to be occupied for work relating to the road, most often in the case of road surface repairs. In the United States road work could also mean any work conducted in close proximity of travel way (thoroughfare) such as utility work or work on power lines (i.e. telephone poles). The general term of road work is known as work zone. Roadworks can, however, also happen when a major accident occurs and road debris from the crash needs to be cleared. Roadworks are often signposted, although it is possible that the signage comes too late or too sudden or is missing. Typical road work traffic controls are temporary signs, traffic cones, barrier boards and t-top bollards as well as other forms of warning devices. There are standards of temporary traffic control ( maintenance of traffic) established in each country for various type of road work. Road ...
