Coordination (the more correct term is progression) refers to the timing of the signals so that a "platoon" of cars traveling on a street arrives at a succession of green lights and proceeds through multiple intersections without stopping. A well coordinated signal system can enhance traffic flow, reduce delay and minimize pollution.
An LED 50-watt traffic light in Portsmouth, United KingdomTraffic 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.
A flashing amber traffic light usually indicates you have a yield or stop sign as a redundant sign, while a turned-off traffic light usually indicates you have the right-of-way. In the UK and parts of North America, drivers simply treat the junction as being uncontrolled when traffic lights fail, giving way as appropriate, unless a police ...
In New Zealand, where traffic is on the left, when a road is given a green light from an all-direction stop, a red arrow can continue to display to turning traffic, holding traffic back while a pedestrian crossing on the side road is given a green signal (for left turns) or while oncoming traffic goes straight ahead and there is no permissive right turn allowed (for right turns).

Sketch and traffic light sequence of a four-way intersection with displaced left turns on two of the legs.
Cameras, microwave motion sensors, and radio-frequency identification (RFID) E-ZPass tag readers are used as inputs as a mean to for monitoring traffic flow. The data is fed through the government-dedicated broadband wireless infrastructure to the traffic management center to be used in adaptive traffic control of the traffic lights. [30]
Will Smith, reflecting on leadership and work-life balance, shares a lesson from his company CEO on emotional check-ins at work. "There's always a red [light]," Smith says. "And you know, when ...
The flow through a diverging diamond interchange using overpasses at the crossovers is limited only by weaving, and the flow through an implementation using traffic lights is subject to only two clearance intervals (the time during which all lights are red so that the intersection may fully clear) per cycle.
