Network Length (transport)
In transport terminology, network length (or, less often, system length) refers to the total length of a transport network, and commonly also refers to the length of any fixed infrastructure associated with the network. A measurement can be made of the network length of various different modes of transport, including rail, bus, road and air. The measurement may focus on one of a number of specific characteristics, such as route length, line length or track length. Lines and routes Continental European and Scandinavian transport network analysts and planners have long had a professional practice of using the following terminology (in their own languages) to draw a distinction between: *a ''line'' – namely "an operational element of public transport system"; and *a ''route'' – as in "the route that bus or rail vehicle follows through the city". In 2000, this terminology was adopted by an English language best practice guide to public transport, to minimise the risk of c ...

Technical Terminology
Jargon is the specialized terminology associated with a particular field or area of activity. Jargon is normally employed in a particular communicative context and may not be well understood outside that context. The context is usually a particular occupation (that is, a certain trade, profession, vernacular or academic field), but any ingroup can have jargon. The main trait that distinguishes jargon from the rest of a language is special vocabulary—including some words specific to it and often different senses or meanings of words, that outgroups would tend to take in another sense—therefore misunderstanding that communication attempt. Jargon is sometimes understood as a form of technical slang and then distinguished from the official terminology used in a particular field of activity. The terms ''jargon'', ''slang,'' and ''argot'' are not consistently differentiated in the literature; different authors interpret these concepts in varying ways. According to one definition, ...

Single Carriageway
A single carriageway (British English) or Undivided highway (American English) is a road with one, two or more lanes arranged within a one carriageway with no central reservation to separate opposing flows of traffic. A single-track road has a single lane with passing places for traffic in both directions. Road traffic safety is generally worse for high-speed single carriageways than for dual carriageways due to the lack of separation between traffic moving in opposing directions. Countries Ireland The term ''single carriageway'' is used for roads in the Republic of Ireland. Road speed limits in the Republic of Ireland, Speed limits on single-carriageway roads vary depending on their classification: national primary roads and national secondary roads have a general speed limit of , while Regional road (Ireland), regional roads and Local Roads in Ireland, local roads have a general speed limit of . In urban areas, the general speed limit is . United Kingdom The maximum Road sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Routing
Routing is the process of selecting a path for traffic in a network or between or across multiple networks. Broadly, routing is performed in many types of networks, including circuit-switched networks, such as the public switched telephone network (PSTN), and computer networks, such as the Internet. In packet switching networks, routing is the higher-level decision making that directs network packets from their source toward their destination through intermediate network nodes by specific packet forwarding mechanisms. Packet forwarding is the transit of network packets from one network interface to another. Intermediate nodes are typically network hardware devices such as routers, gateways, firewalls, or switches. General-purpose computers also forward packets and perform routing, although they have no specially optimized hardware for the task. The routing process usually directs forwarding on the basis of routing tables. Routing tables maintain a record of the routes ...

Typography
Typography is the art and technique of arranging type to make written language legible, readable and appealing when displayed. The arrangement of type involves selecting typefaces, point sizes, line lengths, line-spacing ( leading), and letter-spacing (tracking), as well as adjusting the space between pairs of letters ( kerning). The term ''typography'' is also applied to the style, arrangement, and appearance of the letters, numbers, and symbols created by the process. Type design is a closely related craft, sometimes considered part of typography; most typographers do not design typefaces, and some type designers do not consider themselves typographers. Typography also may be used as an ornamental and decorative device, unrelated to the communication of information. Typography is the work of typesetters (also known as compositors), typographers, graphic designers, art directors, manga artists, comic book artists, and, now, anyone who arranges words, letters, ...

Line Length
In typography, line length is the width of a block of typeset text, usually measured in units of length like inches or points or in characters per line (in which case it is a measure). A block of text or paragraph has a maximum line length that fits a determined design. If the lines are too short then the text becomes disjointed; if they are too long, the content loses rhythm as the reader searches for the start of each line. Line length is determined by typographic parameters based on a formal grid and template with several goals in mind: balance and function for fit and readability with a sensitivity to aesthetic style in typography. Typographers adjust line length to aid legibility or copy fit. Text can be flush left and ragged right, flush right and ragged left, or justified where all lines are of equal length. In a ragged right setting, line lengths vary to create a ragged right edge. Sometimes this can be visually satisfying. For justified and ragged right settings ty ...

Interplanetary Transport Network
The Interplanetary Transport Network (ITN) is a collection of gravitationally determined pathways through the Solar System that require very little energy for an object to follow. The ITN makes particular use of Lagrange points as locations where trajectories through space can be redirected using little or no energy. These points have the peculiar property of allowing objects to orbit around them, despite lacking an object to orbit. While it would use little energy, transport along the network would take a long time. History Interplanetary transfer orbits are solutions to the gravitational three-body problem, which, for the general case, does not have analytical solutions, and is addressed by numerical analysis approximations. However, a small number of exact solutions exist, most notably the five orbits referred to as "Lagrange points", which are orbital solutions for circular orbits in the case when one body is significantly more massive. The key to discovering the Interplan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heuristic Routing
Heuristic routing is a system used to describe how deliveries are made when problems in a network topology arise. Heuristic is an adjective used in relation to methods of learning, discovery, or problem solving. Routing is the process of selecting paths to specific destinations. Heuristic routing is used for traffic in the telecommunications networks and transport networks of the world. Heuristic routing is achieved using specific algorithms to determine a better, although not always optimal, path to a destination. When an interruption in a network topology occurs, the software running on the networking electronics can calculate another route to the desired destination via an alternate available path. According to : The heuristic approach to problem solving consists of applying human intelligence, experience, common sense and certain rules of thumb (or heuristics) to develop an acceptable, but not necessarily an optimum, solution to a problem. Of course, determining what constitute ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Non-revenue Track
Non-revenue track (or trackage), or a non-revenue route, is a section of track or transport route that is not used to carry revenue-earning freight or goods nor for scheduled passenger services. The term is used to refer mainly to sections of track or routes in public transport systems, such as rapid transit and tramway networks, but non-revenue track or routes can also be found in other transport systems. Non-revenue tracks may be used for revenue service during temporary reroutings.

Streetcar
A tram (called a streetcar or trolley in North America) is a rail vehicle that travels on tramway tracks on public urban streets; some include segments on segregated right-of-way. The tramlines or networks operated as public transport are called tramways or simply trams/streetcars. Many recently built tramways use the contemporary term light rail. The vehicles are called streetcars or trolleys (not to be confused with trolleybus) in North America and trams or tramcars elsewhere. The first two terms are often used interchangeably in the United States, with ''trolley'' being the preferred term in the eastern US and ''streetcar'' in the western US. ''Streetcar'' or ''tramway'' are preferred in Canada. In parts of the United States, internally powered buses made to resemble a streetcar are often referred to as "trolleys". To avoid further confusion with trolley buses, the American Public Transportation Association (APTA) refers to them as " trolley-replica buses". In the ...

Tramway Track
Tramway track is used on tramways or light rail operations. Grooved rails (or girder rails) are often used to provide a protective flangeway in the trackwork in city streets. Like standard rail tracks, tram tracks consist of two parallel steel rails. Tram rails can be placed on several surfaces, such as with standard rails on sleepers like railway tracks, or with grooved rails on concrete sleepers into street surfaces ( pavement) for street running. Tram rails in street have the disadvantage that they pose a risk to cyclists. An alternative is to lay tracks into non-road grass turf surfaces; this is known as ''grassed track'' (or ''track in a lawn''), introduced in Liverpool in 1924 - although grassed track is common in rural tramways. History Tramway tracks have been in existence since the mid-16th century. They were previously made of wood, but during the late 18th century iron and later steel came into use prominently. The first street tramways were laid in 1832 in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
