Turnstile
A turnstile (also called a turnpike, gateline, baffle gate, automated gate, turn gate in some regions) is a form of gate which allows one person to pass at a time. A turnstile can be configured to enforce one-way human traffic. In addition, a turnstile can restrict passage only to people who insert a coin, ticket, pass, or other method of payment. Modern turnstiles incorporate biometrics, including retina scanning, fingerprints, and other individual human characteristics which can be scanned. Thus a turnstile can be used in the case of paid access (sometimes called a faregate or ticket barrier when used for this purpose), for example to access public transport, a pay toilet, or to restrict access to authorized people, for example in the lobby of an office building. History Turnstiles were originally used, like other forms of stile, to allow human beings to pass while keeping sheep or other livestock penned in. The use of turnstiles in most modern applications has been credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fare Evasion
Fare evasion or fare dodging, fare violation, rarely called ticket evasion, is the act of travelling on public transport without paying by deliberately not buying a required ticket to travel (having had the chance to do so). It is a problem in many parts of the world, and revenue protection officers and ticket barriers, staffed or automatic, are in place to ensure only those with valid tickets may access the transport. The term fare avoidance is sometimes used as a euphemistic synonym and sometimes used to refer to the lawful use of much cheaper tickets. Fare evasion and fare fraud may or may not be a crime depending on which jurisdictions. The fare not paid, compared to potential penalties and hassle, is generally considered "not worth it". Methods On stations One method of fare evasion is jumping or climbing over the turnstiles which bar the entryway into a subway system; hence the term, "turnstile jumping". Fare-dodgers also can walk right behind a passenger with a valid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Optical Turnstile
An optical turnstile is a physical security device designed to restrict or control access to a building or secure area. Optical turnstiles are usually a part of an access control system, which also consists of software, card readers, and controllers. Optical turnstiles operate much like regular mechanical turnstiles, except that they rely primarily on electronic (infrared) beams, and audible/visual interfaces to control entry. Rather than physically restraining a person, the optical turnstile uses sounds and lights to alert others to attempted entry by unauthorized individuals. The advent of the Americans with Disabilities Act (ADA) drove optical turnstile development because physical barriers for access were no longer legal for public access due to the fact that persons in wheelchairs or with other disabilities could not use them as access points. For this reason, they are not likely to be used in subways and stadiums, as they are suited for settings where design and aesthetics ...

Revolving Door
A revolving door typically consists of three or four doors that hang on a central shaft and rotate around a vertical axis within a cylindrical enclosure. Revolving doors are energy efficient as they, acting as an airlock, prevent drafts, thus decreasing the loss of heating or cooling for the building. Revolving doors were designed to relieve the immense pressure caused by air rushing through high-rise buildings (referred to as stack effect pressure) while at the same time, to allow large numbers of people to pass in and out. Construction Around the central shaft of the revolving door, there are usually three or four panels called "wings" or "leaves." Large diameter revolving doors can accommodate strollers and wheeled luggage racks. Some "revolving door displays" incorporate a small glass enclosure, permitting small objects such as sculpture, fashion mannequins, or plants to be displayed to pedestrians passing through. Such enclosures can either be mounted at the central ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fare Control
In rail transport, the paid area is a dedicated "inner" zone in a railway station or metro station, accessible via turnstiles or other barriers, to get into which, visitors or passengers require a valid ticket, checked smartcard or a pass. A system using paid areas is often called fare control. Passengers are allowed to enter or exit only through a faregate. A paid area usually exists in rapid transit railway stations for separating the train platform from the station exit, ensuring a passenger has paid or prepaid before reaching the railway platform and using any transport service. Such design requires a well-organized railway station layout. In some systems, paid areas are named differently - for example, on railways in the United Kingdom they are called compulsory ticket areas The paid area is similar in concept to the airside at an airport. However, in most cases entrance to the paid area requires only a valid ticket or transit pass. The exception is in certain cases of inter ...

Gate
A gate or gateway is a point of entry to or from a space enclosed by walls. The word derived from old Norse "gat" meaning road or path; But other terms include ''yett and port''. The concept originally referred to the gap or hole in the wall or fence, rather than a barrier which closed it. Gates may prevent or control the entry or exit of individuals, or they may be merely decorative. The moving part or parts of a gateway may be considered "doors", as they are fixed at one side whilst opening and closing like one. A gate may have a latch that can be raised and lowered to both open a gate or prevent it from swinging. Locks are also used on gates to increase the security. Larger gates can be used for a whole building, such as a castle or fortified town. Actual doors can also be considered gates when they are used to block entry as prevalent within a gatehouse. Today, many gate doors are opened by an automated gate operator. Purpose-specific types of gate * Baby gate a safety ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New York City Subway
The New York City Subway is a rapid transit system owned by the government of New York City and leased to the New York City Transit Authority, an affiliate agency of the state-run Metropolitan Transportation Authority (MTA). Opened on October 27, 1904, the New York City Subway is one of the world's oldest public transit systems, one of the most-used, and the one with the most stations, with New York City Subway stations, 472 stations in operation (424 if stations connected by transfers are counted as single stations). Stations are located throughout the boroughs of Manhattan, Brooklyn, Queens, and the Bronx. The system has operated 24/7 service every day of the year throughout most of its history, barring emergencies and disasters. By annual ridership, the New York City Subway is the busiest rapid transit system in both the Western Hemisphere and the Western world, as well as the List of metro systems, seventh-busiest rapid transit rail system in the world. In , the subway deliv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
One-way Traffic
One-way traffic (or uni-directional traffic) is traffic that moves in a single direction. A one-way street is a street either facilitating only one-way traffic, or designed to direct vehicles to move in one direction. One-way streets typically result in higher traffic flow as drivers may avoid encountering oncoming traffic or turns through oncoming traffic. Residents may dislike one-way streets due to the circuitous route required to get to a specific destination, and the potential for higher speeds adversely affecting pedestrian safety. Some studies even challenge the original motivation for one-way streets, in that the circuitous routes negate the claimed higher speeds. Signage General signs Signs are posted showing which direction the vehicles can move in: commonly an upward arrow, or on a T junction where the main road is one-way, an arrow to the left or right. At the end of the street through which vehicles may not enter, a prohibitory traffic sign "Do Not Enter", " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ratchet (device)
A ratchet (occasionally spelled rachet) is a mechanical device that allows continuous linear or rotary motion in only one direction while preventing motion in the opposite direction. Ratchets are widely used in machinery and tools. The word ''ratchet'' is also used informally to refer to a ratcheting socket wrench. __TOC__ Theory of operation A ratchet consists of a round gear or a linear rack with teeth, and a pivoting, spring-loaded finger called a '' pawl'' (or ''click'', in clocks and watches) that engages the teeth. The teeth are uniform but are usually asymmetrical, with each tooth having a moderate slope on one edge and a much steeper slope on the other edge. When the teeth are moving in the unrestricted (i.e. forward) direction, the pawl easily slides up and over the gently sloped edges of the teeth, with a spring forcing it (often with an audible 'click') into the depression between the teeth as it passes the tip of each tooth. When the teeth move in the opposite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stile
A stile is a structure or opening that provides people passage over or through a boundary via steps, ladders, or narrow gaps. Stiles are often built in rural areas along footpaths, fences, walls, or hedges that enclose animals, allowing people to move freely. Types In the United Kingdom many stiles were built under legal compulsion (see Rights of way in the United Kingdom). Recent changes in UK government policy towards farming have encouraged upland landowners to make access more available to the public, and this has seen an increase in the number of stiles and an improvement in their overall condition. However stiles are deprecatedBritish Standard BS5709:2018 Gaps Gates & Stiles () and are increasingly being replaced by gates or kissing gates or, where the field is arable, the stile removed. Many legacy stiles remain, however, in a variety of forms (as is also the case in the US, where there is no standard). As well as having a variety of forms, stiles also sometimes include ...

Clarence Saunders (grocer)
Clarence Saunders (9 August 1881 – 14 October 1953) was an American grocer who first developed the modern retail sales model of self service. His ideas have had a massive influence on the development of the modern supermarket. Saunders worked for most of his life trying to develop a truly automated store, developing Piggly Wiggly, Keedoozle, and Foodelectric store concepts. Early life Saunders was born on a farm in Amherst County, Virginia, to Abram Warwick and Mary Gregory. Saunders' mother died when he was five. Abram had served in the Confederate army under Stonewall Jackson but had struggled financially in the aftermath of the war. In 1891, his father moved the family to Montgomery County, Tennessee, where his father worked as a laborer and sharecropper on a plantation near Palmyra, Tennessee. Saunders worked the plantation as well throughout his early childhood. By age 11, he was also working in a sawmill and limestone kiln during the summer and at a general store during th ...
