Adaptive Traffic Control
Adaptive traffic control system (ATCS) is a traffic management strategy in which traffic signal timing changes, or adapts, based on actual traffic demand. This is accomplished using an adaptive traffic control system consisting of both hardware and software. Every Day Counts initiative The U.S. Federal Highway Administration, through its Every Day Counts initiative, is working to accelerate the adoption of adaptive signal control technologies in the U.S. Its website states, "Real-time management of traffic systems is proven to work, yet these systems have been deployed on less than 1 percent of existing traffic signals. FHWA is now working to bring these technologies to the rest of the country." Examples InSync adaptive traffic control system is a real-time adaptive traffic control system that enables traffic signals to immediately adapt to traffic demand.

Traffic Light
Traffic lights, traffic signals, or stoplights – known also as robots in South Africa are signalling devices positioned at intersection (road), 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 ...

Federal Highway Administration
The Federal Highway Administration (FHWA) is a division of the United States Department of Transportation that specializes in highway transportation. The agency's major activities are grouped into two programs, the Federal-aid Highway Program and the Federal Lands Highway Program. Its role had previously been performed by the Office of Road Inquiry, Office of Public Roads and the Bureau of Public Roads. History Background The organization has several predecessor organizations and complicated history. The Office of Road Inquiry (ORI) was founded in 1893. In 1905, that organization's name was changed to the Office of Public Roads (OPR) which became a division of the United States Department of Agriculture. The name was changed again to the Bureau of Public Roads in 1915 and to the Public Roads Administration (PRA) in 1939. It was then shifted to the Federal Works Agency which was abolished in 1949 when its name reverted to Bureau of Public Roads under the Department of Commerce ...

MASSTR
MASSTR, the' Meadowlands Adaptive Signal System for Traffic Reduction, is an adaptive traffic control system commissioned by the New Jersey Meadowlands Commission (NJMC) for a forty square mile region in the New Jersey Meadowlands. Adaptive Signal Control Technology (ASCT) adjusts the signal timings based upon the flow of traffic instead of utilizing fixed or actuated timings. This regional intelligent transportation system (ITS) incorporates more than 128 traffic signals and serves more than 400,000 vehicles daily. MASSTR is one of a number of ITS projects deployed throughout New Jersey. MASSTR is the fourth-largest deployment of SCATS (Sydney Coordinated Adaptive Traffic System) in the United States. Adaptive Signal Control Technology continuously coordinates and optimizes traffic signal timings rather than utilizing fixed or actuated timings. Signal timings are optimized across jurisdictional boundaries with a central computer system at a Traffic Management Center in the NJMC ...

New Jersey
New Jersey is a state in the Mid-Atlantic and Northeastern regions of the United States. It is bordered on the north and east by the state of New York; on the east, southeast, and south by the Atlantic Ocean; on the west by the Delaware River and Pennsylvania; and on the southwest by Delaware Bay and the state of Delaware. At , New Jersey is the fifth-smallest state in land area; but with close to 9.3 million residents, it ranks 11th in population and first in population density. The state capital is Trenton, and the most populous city is Newark. With the exception of Warren County, all of the state's 21 counties lie within the combined statistical areas of New York City or Philadelphia. New Jersey was first inhabited by Native Americans for at least 2,800 years, with the Lenape being the dominant group when Europeans arrived in the early 17th century. Dutch and Swedish colonists founded the first European settlements in the state. The British later seized control o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Jersey Meadowlands Commission
The New Jersey Meadowlands Commission (NJMC; formerly the Hackensack Meadowlands Development Commission) was a regional zoning, planning and regulatory agency in northern New Jersey. Its founding mandates were to protect the delicate balance of nature, provide for orderly development, and manage solid waste activities in the New Jersey Meadowlands District. The Commission operated as an independent state agency between 1969 and 2015, loosely affiliated with the New Jersey Department of Community Affairs. NJMC was merged with the New Jersey Sports and Exposition Authority through legislative action. Establishment The Meadowlands Commission was established by an Act of the New Jersey Legislature in 1969, sponsored in the New Jersey Senate by Fairleigh S. Dickinson Jr. The merger with the Sports and Exposition Authority was made effective in February 2015. Geographic jurisdiction The Meadowlands District is composed of , approximately 31 mi2, of 14 municipalities in Bergen and ...

Sydney Coordinated Adaptive Traffic System
The Sydney Coordinated Adaptive Traffic System, abbreviated SCATS, is an intelligent transportation system that manages the dynamic (on-line, real-time) timing of signal phases at traffic signals, meaning that it tries to find the best phasing (i.e. cycle times, phase splits and offsets) for a traffic situation (for individual intersections as well as for the whole network). SCATS is based on the automatic plan selection from a library in response to the data derived from loop detectors or other road traffic sensors. SCATS uses sensors at each traffic signal to detect vehicle presence in each lane and pedestrians waiting to cross at the local site. The vehicle sensors are generally inductive loops installed within the road pavement. The pedestrian sensors are usually push buttons. Various other types of sensors can be used for vehicle presence detection, provided that a similar and consistent output is achieved. Information collected from the vehicle sensors allows SCATS to calcul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Detection Camera And Radio On A Traffic Signal Mast Arm
{{Unreferenced, date=March 2018 In general, detection is the action of accessing information without specific cooperation from with the sender. In the history of radio communications, the term "detector" was first used for a device that detected the simple presence or absence of a radio signal, since all communications were in Morse code. The term is still in use today to describe a component that extracts a particular signal from all of the electromagnetic waves present. Detection is usually based on the frequency of the carrier signal, as in the familiar frequencies of radio broadcasting, but it may also involve filtering a faint signal from noise, as in radio astronomy, or reconstructing a hidden signal, as in steganography. In optoelectronics, "detection" means converting a received optical input to an electrical output. For example, the light signal received through an optical fiber is converted to an electrical signal in a detector such as a photodiode. In steganography ...

SURTRAC
Scalable Urban Traffic Control (Surtrac) is an adaptive traffic control system developed by researchers at the Robotics Institute, Carnegie Mellon University. Surtrac dynamically optimizes the control of traffic signals to improve traffic flow for both urban grids and corridors; optimization goals include less waiting, reduced traffic congestion, shorter trips, and less pollution. The core control engine combines schedule-driven intersection control with decentralized coordination mechanisms. Since June 2012, a pilot implementation of the Surtrac system has been deployed on nine intersections in the East Liberty neighbourhood of Pittsburgh, Pennsylvania. Surtrac reduced travel times by more than 25% on average, and wait times were reduced by an average of 40%. A second phase of the pilot program for the Bakery Square district has been running since October 2013. In 2015, Rapid Flow Technologies was formed to commercialise the Surtrac technology. The lead inventor of this technology, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Split Cycle Offset Optimisation Technique
Split Cycle Offset Optimisation Technique (SCOOT) is a real time adaptive traffic control system for the coordination and control of traffic signals across an urban road network. Originally developed by the Transport Research Laboratory for the Department of Transport in 1979, research and development of SCOOT has continued to present day. SCOOT is used extensively throughout the United Kingdom as well as in other countries. SCOOT automatically adjusts the traffic signal timings to adapt to current traffic conditions, using flow data from traffic sensors. Sensor data is usually derived from inductive loops in the carriageway but other forms of detection are increasingly being used. Adjacent signal controlled junctions and pedestrian/cycle crossings are collected together into groups called "regions". SCOOT then calculates the most appropriate signal timings for the region. SCOOT changes the stage lengths or the splits to ensure that the delays are balanced as much as possible, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
