Turnstile
A turnstile (also called a 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 traffic#One-way traffic of people, one-way human traffic. In addition, a turnstile can restrict passage only to people who insert a coin, ticket, transit pass, security credential, or other method of payment or verification. Modern turnstiles can 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 Fare control, 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 excluding live ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Turnstile
Great Turnstile, Little Turnstile and New Turnstile are alleys between High Holborn and Lincoln's Inn Fields in London. They originally had turnstiles to prevent cattle from straying. They later became busy lanes and were built up with shops and housing. Numerous businesses were established there including booksellers, publishers and makers of scientific instruments. Names Great Turnstile, Little Turnstile and New Turnstile link the highway of High Holborn and the open ground of Lincoln's Inn Fields. They are named after the turnstiles which were put there in Tudor times to prevent cattle grazing on the fields from escaping into Holborn. The New Turnstile is so-called because it was created later in 1685. Other names for the Great Turnstile include Turngatlane, Turnstile Alley, Turningstile Lane and Turnepike Lane. It was recorded as Turngatlane in 1522 and records show that it was not built up with shops and housing until after 1545. Shops Shops and other business ...

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 oppo ... [...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", "Wr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gate
A gate or gateway is a point of entry to or from a space enclosed by walls. The word is derived from Proto-Germanic language, Proto-Germanic ''*gatan'', meaning an opening or passageway. Synonyms include yett (which comes from the same root word) and portal (architecture), portal. The concept originally referred to the gap or hole in the wall or fence, rather than a Barricade, 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 "Door, doors", as they are fixed at one side whilst opening and closing like one. A gate may have a latch (hardware), latch that can be raised and lowered to both open a gate or prevent it from swinging. Gate operation can be either Electric gate, automated or manual. Locks are also used on gates to increase security. Larger gates can be used for a whole building, such as a castle or fortified town. Doors can also be considered ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crowd Counting
Crowd counting is the act of counting the total crowd present in a certain area. The people in a certain area are called a crowd. The most direct method is to actually count each person in the crowd. For example, turnstiles are often used to precisely count the number of people entering an event. Modern understanding Since the early 2000s, there has been a shift in the understanding of the phrase “crowd counting”. Having moved from a simpler crowd counting method to that of clusters and density maps, there are several improvements for crowd counting methods. Crowd counting can also be defined as estimating the number of people present in a single picture. Methods of counting crowds Due to the rapid progress in technology and growth of CNN (Convolutional Neural Network) over the last decade, the usage of CNN in crowd counting has skyrocketed. The CNN based methods can largely be grouped under the following different models: Jacobs' method The most common technique for ...

Stile
A stile is a structure or opening that provides passage for humansrather than animals such as livestockover or through a boundary. Common forms include steps, ladders, or narrow gaps. Stiles are often built in rural areas along footpaths, fences, walls, or hedges that enclose domestic animals. 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 ...

Persons With Disabilities
Disability is the experience of any condition that makes it more difficult for a person to do certain activities or have equitable access within a given society. Disabilities may be cognitive, developmental, intellectual, mental, physical, sensory, or a combination of multiple factors. Disabilities can be present from birth or can be acquired during a person's lifetime. Historically, disabilities have only been recognized based on a narrow set of criteria—however, disabilities are not binary and can be present in unique characteristics depending on the individual. A disability may be readily visible, or invisible in nature. The United Nations Convention on the Rights of Persons with Disabilities defines disability as including: Disabilities have been perceived differently throughout history, through a variety of different theoretical lenses. There are two main models that attempt to explain disability in our society: the medical model and the social model. The medica ...

Token (numismatics)
In numismatics, token coins or trade tokens are coin-like objects used instead of coins. The field of token coins is part of exonumia and token coins are token money. Their denomination is shown or implied by size, color or shape. They are often made of cheaper metals like copper, pewter, aluminium, brass and tin, or non-metals like bakelite, leather and porcelain. A legal tender coin is issued by a governmental authority and is freely exchangeable for goods. A token coin has a narrower utility and is issued by a private entity. In many instances, token coins have become obsolete due to the use of cash, payment cards, stored value cards or other electronic transactions. Trade Coin-like objects from the Roman Empire called have been interpreted as an early form of token. Their functions are not documented, but they appear to have been brothel tokens or possibly gaming tokens. Medieval English monasteries issued tokens to pay for services from outsiders.
