	Traffic light - Wikipedia, the free encyclopedia
		Traffic lights for normal vehicles or pedestrians always have two main lights, a red light that means stop and a green (or sometimes white for pedestrians) light that means go.
		Traffic light failure in most jurisdictions must be handled by drivers as a priority-to-the-right intersection in Europe, or a four-way stop elsewhere, pending the arrival of a police officer to direct traffic.
		This elaborate traffic light gantry is in Pleasanton.

	Traffic light coalition - Wikipedia, the free encyclopedia
		Traffic light coalition is a term originating in German politics where it describes a coalition of the Social Democratic Party (SPD), the Free Democratic Party (FDP), and the Green Party.
		At a state level, there have been two traffic light coalitions in Germany: in Brandenburg between 1990 and 1994 and in Bremen between 1991 and 1995.
		However, as the Liberal Forum's party colour is light blue, this is a reference to the political similarity between this coalition and a German traffic light coalition rather than to the party's actual symbolic colours.

	Intelligent Traffic Light Control
		Intelligent traffic light control does not only mean that traffic lights are set in order to minimize waiting times of road users, but also that road users receive information about how to drive through a city in order to minimize their waiting times.
		Now the traffic light has to decide which option (ie, which lanes are to be put on green) is optimal to minimize the long-term average waiting time until all cars have arrived at their destination address.
		Note that we solve the traffic light control problem by using a distributed multi-agent system, where cooperation and coordination are done by communication, learning, and voting mechanisms.

	#1 Traffic light audio monitor to control and monitor the sound level in schools.
		We have had some fairly poor districts do a lot of fundraising to pay for a light and in almost all cases they report that it was worth the effort to purchase the correct traffic light audio monitor.
		This light, at $40, was inexpensive and would "test" their idea for a bigger and better light.
		They just bought a real traffic light (which are huge when you see them up close), installed it in the lunchroom to be in view of every kid, and put someone in charge of it during lunchtime every day.

	The first traffic light
		Traffic lights were used before the advent of the motorcar.
		In 1868, a lantern with red and green signals was used at a London intersection to control the flow of horse buggies and pedestrians.
		The first automatic traffic light was invented later in 1920 by Garrett Morgan and first used in Cleveland, Ohio, USA.

	EvoWeb - Evolution@work - Optimising traffic light control (Site not responding. Last check: 2007-09-20)
		The controller was developed for the congested public road system in the Netherlands, where traffic problems are compounded by the number of intersections that are controlled by traffic lights.
		Consequently, improving traffic flow at intersections is crucial to improving the overall traffic situation.
		Traffic light control systems are generally optimised by hand or, if feasible, with an analytical approach.

	Traffic light sensors
		All the associated traffic lights have directional antennas aimed at the base station (which is on Ft. Reno Dr. and Wisconsin Ave.

		The object of this project is to simulate traffic light model which is smarter than traditional traffic light model.
		That is if the traffic on any one of lane is high, then the corresponding traffic sensor is set to green until all the traffic is cleared.
		The traffic lights are controlled by the traffic light controller, which sets the green, yellow, red light for certain amount of time.

	Traffic light sequencing - boards.ie
		This might seem trivial but the reason i ask is that at a junction i pass through every day, the green light is biased in favour of the 'minor' road than the more busier one opposite.
		Remember one of the main functions of traffic lights is to BREAK UP the flow of traffic so there is less downstream congestion.
		Traffic lights are not just about getting the maximum traffic through a particular junction..

	Traffic Light Tripper
		Use a traffic light tripper to prevent sitting at a red traffic light which refuses to change to green.
		The answer is to fit a traffic light tripper, and let the traffic lights know that you are there!
		Our traffic light tripper is a magnetic device that, when attached to the underside of a vehicle, allows the electromagnets that control traffic signals at intersections to detect it, thereby tripping the controlling mechanism of the traffic light.

	Selectmen want first traffic light: 4/26/00
		Selectmen said that it is greatly needed due to the rerouted traffic from the closing of the Gurney Road Bridge.
		Koczera said it is more likely the town will get a flashing warning light rather than a full-fledged stop light since the Massachusetts Highway Department believes the amount of traffic generated at the intersection does not warrant a traffic light.
		Selectman Lawrence Ashley, who will be on the losing end of a bet with fellow Selectman John Ashley should a flashing beacon be put in rather than a traffic light, was upset at the possibility of a flashing beacon.

	traffic light cameras
		If the amber light appears you may go on only if you have already crossed the stop line or are so close to it that to stop might cause an accident.
		Only go forward when the traffic lights are green if there is room for you to clear the junction safely or you are taking up a position to turn right.
		You can't, but the lights should be timed so that if you are driving within the limit and are too close to stop, you would go through on amber, entirely legally.

	Howstuffworks "Why are they replacing all of the traffic lights in my town?"
		The new traffic lights you are seeing are made out of arrays of light emitting diodes (LEDs).
		These are tiny, purely electronic lights that are extremely energy efficient and have a very long life.
		The light is on 24 hours a day, so it uses 2.4 kilowatt-hours per day.

	Howstuffworks "How does a traffic light detect that a car has pulled up and is waiting for the light to change?"
		For example, in a large city, the traffic lights may simply operate on timers -- no matter what time of day it is, there is going to be a lot of traffic.
		They may detect when a car arrives at an intersection, when too many cars are stacked up at an intersection (to control the length of the light), or when cars have entered a turn lane (in order to activate the arrow light).
		What you see here is a battery, a light bulb, a coil of wire around a piece of iron (yellow), and a switch.

		Traffic lights and stop signs are designed to control the flow of traffic, not as speed controls or pedestrian safety devices.
		Drivers will speed up to make it through a traffic light, and will often ignore a stop sign in a new location.
