Bollard
A bollard is a sturdy, short, vertical post. The term originally referred to a post on a ship or quay used principally for mooring boats. In modern usage, it also refers to posts installed to control road traffic and posts designed to prevent automotive vehicles from colliding with pedestrians and structures. Etymology The term is probably related to bole, meaning a tree trunk. The earliest citation given by the ''Oxford English Dictionary'' (referring to a maritime bollard) dates from 1844, although a reference in the '' Caledonian Mercury'' in 1817 describes bollards as huge posts. History Wooden posts were used for basic traffic management from at least the second half of the 17th century. One early well-documented case is that of the "postes and rales in ye King's highway for ye (safety) of all foot passengers" erected in 1671 in the High Street of Old Brentford, Middlesex (part of the London–Bath road). Another is that of "two oak-posts" set up next to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vehicle-ramming Attack
A vehicle-ramming attack, also known as a vehicle as a weapon or VAW attack, is an assault in which a perpetrator deliberately rams a vehicle into a building, people, or another vehicle. According to Stratfor Global Intelligence analysts, this attack represents a relatively new militant tactic that could prove more difficult to prevent than suicide bombings. Deliberate vehicle-ramming into a crowd of people is a tactic used by terrorists, becoming a major terrorist tactic in the 2010s because it requires little skill to perpetrate, cars and trucks are widely available, and it has the potential to cause significant casualties. Deliberate vehicle-ramming has also been carried out in the course of other types of crimes, including road rage incidents. Deliberate vehicle-ramming incidents have also sometimes been ascribed to the driver's psychiatric disorder.Alan R.

Mooring
A mooring is any permanent structure to which a seaborne vessel (such as a boat, ship, or amphibious aircraft) may be secured. Examples include quays, wharfs, jetties, piers, anchor buoys, and mooring buoys. A ship is secured to a mooring to forestall free movement of the ship on the water. An ''anchor mooring'' fixes a vessel's position relative to a point on the bottom of a waterway without connecting the vessel to shore. As a verb, ''mooring'' refers to the act of attaching a vessel to a mooring. The term likely stems from the Dutch verb ''meren'' (to ''moor''), used in English since the end of the 15th century. Permanent anchor mooring These moorings are used instead of temporary anchors because they have considerably more holding power. They cause lesser damage to the marine environment, and are convenient. Where there is a row of moorings they are termed a tier. They are also occasionally used to hold floating docks in place. There are several kinds of moor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bitts
Bitts are paired vertical wooden or metal posts mounted either aboard a ship or on a wharf, pier, or quay. The posts are used to secure mooring lines, ropes, hawsers, or cables. Bitts aboard wooden sailing ships (sometime called cable-bitts) were large vertical timbers mortised into the keel and used as the anchor cable attachment point. Bitts are carefully manufactured and maintained to avoid any sharp edges that might chafe and weaken the mooring lines. Use Mooring lines may be laid around the bitts either singly or in a figure-8 pattern with the friction against tension increasing with each successive turn. As a verb ''bitt'' means to take another turn increasing the friction to slow or adjust a mooring ship's relative movement.

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 ...

Street Furniture
Street furniture is a collective term for objects and pieces of equipment installed along streets and roads for various purposes. It includes bench (furniture), benches, traffic barriers, bollards, post boxes, phone boxes, streetlamps, traffic lights, traffic signs, bus stops, tram stops, taxi stands, Toilet#Public toilets, public lavatories, fountains, watering troughs, memorials, public art, public sculptures, and waste receptacles. Description and use Street furniture is a collective term used in the United States, United Kingdom, Australia, and Canada. It refers to objects and pieces of equipment installed along streets and roads for various purposes. The design and placement of furniture should take into account aesthetics, visual identity, function, pedestrian mobility and road safety. For example, street furniture can be positioned to control overspill parking in addition to its primary purpose; for example a bench and a number of bollards may be used to block access t ...

Sidewalks
A sidewalk (North American English), pavement (British English, South African English), or footpath (Irish English, Indian English, Australian English, New Zealand English) is a path along the side of a road. Usually constructed of concrete, pavers, brick, stone, or asphalt, it is designed for pedestrians. A sidewalk is normally higher than the roadway, and separated from it by a curb. There may also be a planted strip between the sidewalk and the roadway and between the roadway and the adjacent land. Terminology The preferred term for a pedestrian path beside a road varies based on region. The term "sidewalk" is preferred in most of the United States and Canada. The term "pavement" is more common in the United Kingdom and some other members of the Commonwealth of Nations, as well as parts of the Mid-Atlantic United States such as Philadelphia and parts of New Jersey. Australia, New Zealand, and many other Commonwealth countries use the term "footpath". In the Un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overspill Parking
Overspill parking is the parking of vehicles beyond a defined area specifically designed for this purpose. It can occur because provided parking spaces are insufficient for demand or considered unsatisfactory, and may have unintended consequences on its surroundings. Additional official parking may be provided for an event, or at some distance from the intended destination. Overspill car parking may simply be parking further away from a place than desirable. In some circumstances it may involve parking violations or other unauthorised or anti-social parking such as double parking, parking on verges or on sidewalks and can on occasions create difficulties for others. Available parking may be insufficient, unsuitable, expensive or otherwise undesirable. Parking may be limited because the urban form historically made little provision for the parking of private vehicles, or because the transport authority zoning policies consciously limit the provision of parking spaces to discourage ...

Intersection (road)
An intersection or an at-grade junction is a junction where two or more roads converge, diverge, meet or cross at the same height, as opposed to an interchange, which uses bridges or tunnels to separate different roads. Major intersections are often delineated by gores and may be classified by road segments, traffic controls and lane design. This article primarily reflects practice in jurisdictions where vehicles are driven on the right. If not otherwise specified, "right" and "left" can be reversed to reflect jurisdictions where vehicles are driven on the left. Types Road segments One way to classify intersections is by the number of road segments (arms) that are involved. * A three-way intersection is a junction between three road segments (arms): a T junction when two arms form one road, or a Y junction, the latter also known as a fork if approached from the stem of the Y. * A four-way intersection, or crossroads, usually involves a crossing over of two streets or ...
