Selective Vehicle Detection
Selective vehicle detection is, or was, the name of a bus priority system used by London Buses to allow traffic signals to selectively favour buses' movement through intersection by changing traffic light sequences and timings as buses approach. , the system worked using 'bus detectors' mounted on lampposts and similar posts by the side of the road, which detect transmission made by transmitters aboard buses, developed as part of Transport for London's Countdown A countdown is a sequence of backward counting to indicate the time remaining before an event is scheduled to occur.

Bus Priority
Bus priority or transit signal priority (TSP) is a name for various techniques to improve service and reduce delay for public transport, mass transit vehicles at intersections (or junctions) controlled by traffic signals. TSP techniques are most commonly associated with buses, but can also be used along tram, tram/streetcar or light rail lines, especially those that street running, mix with or conflict with general vehicular traffic. Techniques Transit signal priority techniques can generally be classified as "active" or "passive". Passive TSP techniques typically involve optimizing signal timing or coordinating successive signals to create a “green wave” for traffic along the transit line's route. Passive techniques require no specialized hardware (such as bus detectors and specialized traffic signal controllers) and rely on simply improving traffic for ''all'' vehicles along the transit vehicle's route. Active TSP techniques rely on detecting transit vehicles as they appr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
London Buses
London Buses is the subsidiary of Transport for London (TfL) that manages most bus services in London, England. It was formed following the Greater London Authority Act 1999 that transferred control of London Regional Transport (LRT) bus services to TfL, controlled by the Mayor of London. Overview Transport for London's key areas of direct responsibility through London Buses are the following: * planning new bus routes, and revising existing ones * specifying service levels * monitoring service quality * management of bus stations and bus stops * assistance in 'on ground' set up of diversions, bus driver assistance in situations over and above job requirements, for example Road Accidents * providing information for passengers in the form of timetables and maps at bus stops and online, and an online route planning service * producing leaflet maps, available from Travel Information Centres, libraries etc., and as online downloads. * operating NMCC, London Buses' 24‑hour c ...

Traffic Light Sequence
Traffic comprises pedestrians, vehicles, ridden or herded animals, trains, and other conveyances that use public ways (roads) for travel and transportation. Traffic laws govern and regulate traffic, while rules of the road include traffic laws and informal rules that may have developed over time to facilitate the orderly and timely flow of traffic. Organized traffic generally has well-established priorities, lanes, right-of-way, and traffic control at intersections. Traffic is formally organized in many jurisdictions, with marked lanes, junctions, intersections, interchanges, traffic signals, or signs. Traffic is often classified by type: heavy motor vehicle (e.g., car, truck), other vehicle (e.g., moped, bicycle), and pedestrian. Different classes may share speed limits and easement, or may be segregated. Some jurisdictions may have very detailed and complex rules of the road while others rely more on drivers' common sense and willingness to cooperate. Organization typ ...

Countdown (TfL System)
A countdown is a sequence of backward counting to indicate the time remaining before an event is scheduled to occur. NASA commonly employs the terms "L-minus" and "T-minus" during the preparation for and anticipation of a rocket launch, and even "E-minus" for events that involve spacecraft that are already in space, where the "T" could stand for "Test" or "Time", and the "E" stands for "Encounter", as with a comet or some other space object. Other events for which countdowns are commonly used include the detonation of an explosive, the start of a race, the start of the New Year, or any anxiously anticipated event. An early use of a countdown once signaled the start of a Cambridge University rowing race. One of the first known associations with rockets was in the 1929 German science fiction movie ''Frau im Mond'' (English: ''Woman in the Moon'') written by Thea von Harbou and directed by Fritz Lang in an attempt to increase the drama of the launch sequence of the story's lunar-bo ...

IBus (London)
iBus is an Automatic Vehicle Location (AVL) system to improve London's buses using technology installed by Siemens AG. The system tracks all of London's 9300 buses to provide passengers with audio-visual announcements, improved information on bus arrivals, and to trigger priority at traffic junctions. On 16 June 2005 it was reported that London's buses 'fail' deaf people. As a result, the iBus system was announced on 16 January 2006 and was tried on route 149 for an eight-week trial. The system was proved to be successful, and on 18 May 2006, radio presenter Emma Hignett was announced to be the 'Voice of London's Buses' after 99% in the survey said she had the right voice. iBus was launched on many routes in 2007 and continued throughout 2008 and 2009. All routes now have the system. Announcements Upon boarding the bus, for example, route 240 serving Edgware, iBus plays the announcement "240 to Edgware Station" and corresponding text appears on the visual displays. As the ...

Traffic Signals
Traffic lights, traffic signals, or stoplights – known also as robots in South Africa are signalling devices positioned at road intersections, pedestrian crossings, and other locations in order to control flows of traffic. Traffic lights consist normally of three signals, transmitting meaningful information to drivers and riders through colours and symbols including arrows and bicycles. The regular traffic light colours are red, yellow, and green arranged vertically or horizontally in that order. Although this is internationally standardised,1968, as revised 1995 and 2006Vienna Convention on Road Signs and Signals United Nations Publication ECE/TRANS/196. ISBN 978-92-1-116973-7. URL Accessed: 7 January 2022. variations exist on national and local scales as to traffic light sequences and laws. The method was first introduced in December 1868 on Parliament Square in London to reduce the need for police officers to control traffic. Since then, electricity and computerised co ...

Road Transport In London
A road is a linear way for the conveyance of traffic that mostly has an improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets, the main function of roads is transportation. There are many types of roads, including parkways, avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, thoroughfares, and local roads. The primary features of roads include lanes, sidewalks (pavement), roadways (carriageways), medians, shoulders, verges, bike paths (cycle paths), and shared-use paths. Definitions Historically many roads were simply recognizable routes without any formal construction or some maintenance. The Organization for Economic Co-operation and Development (OECD) defines a road as "a line of communication (travelled way) using a stabilized base other than rails or air strips open to public traffic, primarily for the use of road motor vehicles running on their own wheels", whi ...

Bus Transport In London
A bus (contracted from omnibus, with variants multibus, motorbus, autobus, etc.) is a road vehicle that carries significantly more passengers than an average car or van. It is most commonly used in public transport, but is also in use for charter purposes, or through private ownership. Although the average bus carries between 30 and 100 passengers, some buses have a capacity of up to 300 passengers. The most common type is the single-deck rigid bus, with double-decker and articulated buses carrying larger loads, and midibuses and minibuses carrying smaller loads. Coaches are used for longer-distance services. Many types of buses, such as city transit buses and inter-city coaches, charge a fare. Other types, such as elementary or secondary school buses or shuttle buses within a post-secondary education campus, are free. In many jurisdictions, bus drivers require a special large vehicle licence above and beyond a regular driving licence. Buses may be used for scheduled ...
