Motorway Incident Detection And Automatic Signalling
Motorway Incident Detection and Automatic Signalling, usually abbreviated to MIDAS, is a UK distributed network of traffic sensors, mainly inductive loops, (trialling at the moment radar technology by Wavetronix and magneto-resistive wireless sensors by Clearview Intelligence) which are designed to alert the local regional control centre (RCC) to traffic flow and average speeds, and set variable message signs and advisory speed limits (or mandatory speed limits on smart motorways) with little human intervention. Companies such as RAC, TomTom and Google use this traffic flow data via halogens reporting systems. Originally installed on the congested western stretch of the M25 motorway, much of the M60 motorway around Manchester and the Birmingham box (M6, M5 and M42), MIDAS has been installed on all but the most minor stretches of UK motorway. The system has successfully reduced accidents. Additionally, the system is installed on parts of the non-motorway trunk road network incl ...

Traffic
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 ...

Variable-message Sign
A variable- (also changeable-, electronic-, or dynamic-) message sign, often abbreviated VMS, CMS, or DMS, and in the UK known as a matrix sign, is an electronic traffic sign often used on roadways to give travelers information about special events. Such signs warn of traffic congestion, accidents, incidents such as terrorist attacks, AMBER/Silver/Blue Alerts, roadwork zones, or speed limits on a specific highway segment. In urban areas, VMS are used within parking guidance and information systems to guide drivers to available car parking spaces. They may also ask vehicles to take alternative routes, limit travel speed, warn of duration and location of the incidents, inform of the traffic conditions, or display general public safety messages. History VMS systems were deployed at least as early as the 1950s on the New Jersey Turnpike. The NJ Turnpike's signs of that period, and up to around 2012, were capable of displaying a few messages in neon, all oriented around warning d ...

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 ...

Automotive Safety
Automotive safety is the study and practice of design, construction, equipment and regulation to minimize the occurrence and consequences of traffic collisions involving motor vehicles. Road traffic safety more broadly includes roadway design. One of the first formal academic studies into improving motor vehicle safety was by Cornell Aeronautical Laboratory of Buffalo, New York. The main conclusion of their extensive report is the crucial importance of seat belts and padded dashboards. However, the primary vector of traffic-related deaths and injuries is the disproportionate mass and velocity of an automobile compared to that of the predominant victim, the pedestrian. According to the World Health Organization (WHO), 80% of cars sold in the world are not compliant with main safety standards. Only 40 countries have adopted the full set of the seven most important regulations for car safety. In the United States, a pedestrian is injured by a motor vehicle every 8 minutes, and a ...

Freeway Traffic Management System
COMPASS, also referred to as Freeway Traffic Management System, is a system run by the Ministry of Transportation of Ontario (MTO) to monitor and manage the flow of traffic on various roads (including 400-series highways) in Ontario. COMPASS uses pairs of in-road sensors to detect the speed and density of traffic flow. This data is fed to a central computer at the MTO Downsview office and analyzed by operators, who also view the feeds of traffic cameras placed along the highways. Changeable Message Signs (CMS) then display messages to motorists on the highways, advising them of upcoming collisions, closures, detours and traffic flow. Algorithms The primary algorithm used by the Ministry is known as the McMaster algorithm, designed by Professor Fred Hall of McMaster University, in Hamilton, Ontario. Incident Detection algorithms have also been widely used throughout the COMPASS-enabled area. Research on new algorithm developments and evaluations is performed at the ITS Centre and ...

Electronic Monitoring And Advisory System
The Expressway Monitoring and Advisory System (Simplified Chinese, Chinese: 电子监控与信息系统), also known by its acronym of EMAS, is a computerised system that is used to monitor traffic on Singapore's expressways of Singapore, expressways. EMAS enables Land Transport Authority (LTA) personnel to detect road traffic accident, accidents and respond to them more quickly. In addition, it notifies motorists of adverse traffic conditions. History The contract for the construction of EMAS was awarded by the LTA to Singapore Technologies Electronics in December 1996. The first phase, implemented only on the Central Expressway, Singapore, Central Expressway, was launched officially on 21 March 1998 by then Minister of State for Communications, John Chen (Singaporean), John Chen. In addition, tunnels were originally used by General Electric between 1991 and 1999.

M1 Motorway
The M1 motorway connects London to Leeds, where it joins the A1(M) near Aberford, to connect to Newcastle. It was the first inter-urban motorway to be completed in the UK; the first motorway in the country was the Preston By-pass, which later became part of the M6. The motorway is long and was constructed in four phases. Most of the motorway was opened between 1959 and 1968. The southern end was extended in 1977 and the northern end was extended in 1999. History There had been plans before the Second World War for a motorway network in the United Kingdom. Lord Montagu formed a company to build a 'motorway like road' from London to Birmingham in 1923, but it was a further 26 years before the Special Roads Act 1949 was passed, which allowed for the construction of roads limited to specific vehicle classifications, and in the 1950s, the country's first motorways were given the government go-ahead. The first section of motorway was the Preston Bypass in Lancashire, now par ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
A14 Road (England)
The A14 is a major trunk road in England, running from Catthorpe Interchange, a major intersection at the southern end of the M6 and junction 19 of the M1 in Leicestershire to the Port of Felixstowe, Suffolk. The road forms part of the unsigned Euroroutes E24 and E30. It is the busiest shipping lane in East Anglia carrying anything from cars to large amounts of cargo between the UK and Mainland Europe. Route Beginning at the Catthorpe Interchange, the A14 runs through Kettering, Northamptonshire towards Huntingdon where it now runs parallel to the A1 past Brampton, Cambridgeshire and now bypasses Huntingdon completely due to the A14 Cambridge to Huntingdon Scheme from 2017 until 2022. It continues past Bar Hill towards Cambridge to meet the end of the M11 and the A428 at the Girton Interchange. The A14 continues easterly over northern Cambridge towards Newmarket where it briefly joins with the A11 to form the Newmarket Bypass between J36 and J38. The A11 splits off again t ...

Sensor
A sensor is a device that produces an output signal for the purpose of sensing a physical phenomenon. In the broadest definition, a sensor is a device, module, machine, or subsystem that detects events or changes in its environment and sends the information to other electronics, frequently a computer processor. Sensors are always used with other electronics. Sensors are used in everyday objects such as touch-sensitive elevator buttons (tactile sensor) and lamps which dim or brighten by touching the base, and in innumerable applications of which most people are never aware. With advances in micromachinery and easy-to-use microcontroller platforms, the uses of sensors have expanded beyond the traditional fields of temperature, pressure and flow measurement, for example into Attitude and heading reference system, MARG sensors. Analog sensors such as potentiometers and force-sensing resistors are still widely used. Their applications include manufacturing and machinery, airplane ...

Manchester
Manchester () is a city in Greater Manchester, England. It had a population of 552,000 in 2021. It is bordered by the Cheshire Plain to the south, the Pennines to the north and east, and the neighbouring city of Salford to the west. The two cities and the surrounding towns form one of the United Kingdom's most populous conurbations, the Greater Manchester Built-up Area, which has a population of 2.87 million. The history of Manchester began with the civilian settlement associated with the Roman fort ('' castra'') of ''Mamucium'' or ''Mancunium'', established in about AD 79 on a sandstone bluff near the confluence of the rivers Medlock and Irwell. Historically part of Lancashire, areas of Cheshire south of the River Mersey were incorporated into Manchester in the 20th century, including Wythenshawe in 1931. Throughout the Middle Ages Manchester remained a manorial township, but began to expand "at an astonishing rate" around the turn of the 19th century. Manchest ...

M60 Motorway
The M60 motorway, Manchester Ring Motorway or Manchester Outer Ring Road is an orbital motorway in North West England. Built over a 40-year period, it passes through most of Greater Manchester's metropolitan boroughs except for Wigan and Bolton. Most of Manchester is encompassed within the motorway, except for the southernmost part of the city (Wythenshawe and Manchester Airport) which is served by the M56. The M60 is long and was renamed the M60 in 1998, with parts of the M62, M66 and all of the M63 being amalgamated into the new route, and the circle completed in 2000. The road forms part of the unsigned Euroroutes E20 and E22. In 2008, the M60 was proposed as a cordon for congestion charging in Greater Manchester, although this was rejected in a referendum relating to the Greater Manchester Transport Innovation Fund. History The M60 was developed by connecting and consolidating the existing motorway sections of the M63, M62, and an extended M66. It came into e ...
