Integrated Transport Network
The Integrated Transport Network (ITN) is a dataset containing details of Great Britain's transport network. Produced by Ordnance Survey – the national mapping agency of Great Britain – it forms part of the OS MasterMap suite of products. Intended to facilitate route planning and resource management, the dataset consists of three elements: Road Network (road geometry), Road Routing Information (routing information for drivers concerning mandatory and banned turns and other restrictions) and Urban Paths (man-made path geometry in urban areas). The network is a link-and-node based network containing such details about each link as: *the class of road (A-road, B-road, etc.); *the nature of the road (single carriageway, dual carriageway, roundabout, etc.); *road names; *road routing information (RRI) (e.g. prohibited turns, one-way streets). These data are supplied in Geography Markup Language file format. Features The main benefits claimed for this product are that * ...

Great Britain
Great Britain is an island in the North Atlantic Ocean off the northwest coast of continental Europe. With an area of , it is the largest of the British Isles, the largest European island and the ninth-largest island in the world. It is dominated by a maritime climate with narrow temperature differences between seasons. The 60% smaller island of Ireland is to the west—these islands, along with over 1,000 smaller surrounding islands and named substantial rocks, form the British Isles archipelago. Connected to mainland Europe until 9,000 years ago by a landbridge now known as Doggerland, Great Britain has been inhabited by modern humans for around 30,000 years. In 2011, it had a population of about , making it the world's third-most-populous island after Java in Indonesia and Honshu in Japan. The term "Great Britain" is often used to refer to England, Scotland and Wales, including their component adjoining islands. Great Britain and Northern Ireland now constitute the ...

Network Topology
Network topology is the arrangement of the elements ( links, nodes, etc.) of a communication network. Network topology can be used to define or describe the arrangement of various types of telecommunication networks, including command and control radio networks, industrial fieldbusses and computer networks. Network topology is the topological structure of a network and may be depicted physically or logically. It is an application of graph theory wherein communicating devices are modeled as nodes and the connections between the devices are modeled as links or lines between the nodes. Physical topology is the placement of the various components of a network (e.g., device location and cable installation), while logical topology illustrates how data flows within a network. Distances between nodes, physical interconnections, transmission rates, or signal types may differ between two different networks, yet their logical topologies may be identical. A network’s physical topology is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Britain Road Numbering Scheme
The Great Britain road numbering scheme is a numbering scheme used to classify and identify all roads in Great Britain. Each road is given a single letter (which represents the road's category) and a subsequent number (between 1 and 4 digits). Introduced to arrange funding allocations, the numbers soon became used on maps and as a method of navigation. Two sub-schemes exist: one for motorways, and another for non-motorway roads. While some major roads form part of the International E-road network, no E-routes are signposted in Great Britain, or the rest of the UK. Due to changes in local road designation, in some cases roads are numbered out of zone. There are also instances where road numbers in one area are also found in another location. For example the A594 is designated as the Leicester Ring Road and also allocated to a road in Cumbria. The scheme applies only to England, Scotland and Wales; a similar system is used in Northern Ireland, as well as outside the UK in the I ...

Roundabout
A roundabout is a type of circular intersection or junction in which road traffic is permitted to flow in one direction around a central island, and priority is typically given to traffic already in the junction.''The New Shorter Oxford English Dictionary,'' Volume 2, Clarendon Press, Oxford (1993), page 2632 Engineers use the term modern roundabout to refer to junctions installed after 1960 that incorporate various design rules to increase safety. Both modern and non-modern roundabouts, however, may bear street names or be identified colloquially by local names such as rotary or traffic circle. Compared to stop signs, traffic signals, and earlier forms of roundabouts, modern roundabouts reduce the likelihood and severity of collisions greatly by reducing traffic speeds and minimizing T-bone and head-on collisions. Variations on the basic concept include integration with tram or train lines, two-way flow, higher speeds and many others. For pedestrians, traffic exiting th ...

Geography Markup Language
The Geography Markup Language (GML) is the XML grammar defined by the Open Geospatial Consortium (OGC) to express geographical features. GML serves as a modeling language for geographic systems as well as an open interchange format for geographic transactions on the Internet. Key to GML's utility is its ability to integrate all forms of geographic information, including not only conventional "vector" or discrete objects, but coverages (see also GMLJP2) and sensor data. GML model GML contains a rich set of primitives which are used to build application specific schemas or application languages. These primitives include: * Feature * Geometry * Coordinate reference system * Topology * Time * Dynamic feature * Coverage (including geographic images) * Unit of measure * Directions * Observations * Map presentation styling rules The original GML model was based on the World Wide Web Consortium's Resource Description Framework (RDF). Subsequently, the OGC introduced XML schemas in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transport Direct Portal
The Transport Direct Portal was a distributed Internet-based multi-modal journey planner providing information for travel in England, Wales and Scotland. It was managed by Transport Direct, a division of the Department for Transport. It was launched in 2004 and was operated by a consortium led by Atos and later enhanced to include a cycle journey planning function. The closure of the portal was announced in September 2014 and the portal closed on 30 September 2014. Operation The portal offered a door-to-door journey planner which allowed the user to compare different transport modes including car, rail, bus and coach, air, walking and cycling. Specific features included: * Routing using one or more modes: local bus, coaches, rail and walking. * Cycle journey planning for 32 towns and counties. * Car routing that takes into account likely traffic congestion based on past experience and can route to a suitable car park or park and ride site. * Internal flight routing in Great Bri ...

Bicycle
A bicycle, also called a pedal cycle, bike or cycle, is a human-powered or motor-powered assisted, pedal-driven, single-track vehicle, having two wheels attached to a frame, one behind the other. A is called a cyclist, or bicyclist. Bicycles were introduced in the 19th century in Europe. By the early 21st century, more than 1 billion were in existence. These numbers far exceed the number of cars, both in total and ranked by the number of individual models produced. They are the principal means of transportation in many regions. They also provide a popular form of recreation, and have been adapted for use as children's toys, general fitness, military and police applications, courier services, bicycle racing, and bicycle stunts. The basic shape and configuration of a typical upright or "safety bicycle", has changed little since the first chain-driven model was developed around 1885. However, many details have been improved, especially since the advent of modern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CycleNetXChange
CycleNetXChange provides a standard format with which to exchange cycle path data, together with information about the quality of routes; This enables computerised transport systems to provide cycle routes. This UK National Cycle Path network schema (CycleNetXChange) defines an exchange format for an exchange of cycle path data together with information relevant to cycling about the quality of routes; . It is a component of the UK national transport information infrastructure and is based on a number of other UK and ISO standards. The format allows cycle path data to be collected by different communities and exchanged to provide cycle Journey planners and other navigation products. The CycleNetXChange schema is in draft and is intended to become a UK national de facto standard sponsored by the UK Department of Transport. CycleNet is based on the Ordnance Survey DNF (Digital National Framework) for referencing objects and the ITN (Integrated Transport Network) schema and can ...
