Smart traffic light. Smart traffic lights or Intelligent traffic lights are a vehicle traffic control system that combines traditional traffic lights with an array of sensors and artificial intelligence to intelligently route vehicle and pedestrian traffic. [1] They can form part of a bigger intelligent transport system.
In Australia and New Zealand, the terminology is different. A "phase" is a period of time during which a set of traffic movements receive a green signal - equivalent to the concept of a "stage" in UK and US. One electrical output from the traffic signal controller is called a "signal group" - similar to the UK and US concept of "phase".
Traffic light. An LED 50- watt traffic light in Portsmouth, United Kingdom. Traffic lights, traffic signals, or stoplights – also known as robots in South Africa, [1][2] Zambia, and Namibia – are signaling devices positioned at road intersections, pedestrian crossings, and other locations in order to control the flow of traffic.

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 [ 1 ] for the Department of Transport in 1979, research and development of SCOOT has continued to present day.
HAWK beacon. A HAWK beacon (high-intensity activated crosswalk beacon) is a traffic control device used to stop road traffic and allow pedestrians to cross safely. It is officially known as a pedestrian hybrid beacon. The purpose of a HAWK beacon is to allow protected pedestrian crossings, stopping vehicular traffic only as needed.
All-way stop. An all-way stop – also known as a four-way stop (or three-way stop etc. as appropriate) – is a traffic management system which requires vehicles on all the approaches to a road intersection to stop at the intersection before proceeding through it. Designed for use at low traffic-volume locations, the arrangement is common in ...
Scalable Urban Traffic Control (SURTRAC) [1] [2] is an adaptive traffic control system developed by researchers at the Robotics Institute, Carnegie Mellon University.SURTAC 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.
Arduino. Arduino (/ ɑːrˈdwiːnoʊ /) is an Italian open-source hardware and software company, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices. Its hardware products are licensed under a CC BY-SA license, while the software is licensed under the GNU ...
