Traffic Light Signals

Traffic lighting is used to control the flow of traffic. They're also known as traffic lamps, stop lights, stop and go lights and robots. These are designed specifically for use as signalling devices and are generally positioned where the road intersects with flows of traffic, be it motor vehicles or visitors, such as pedestrian crossings, a crossroads or some other locations to control the flow of traffic.

Most of the cities around the world have these installed to see the road users through lights in standard colours. Large code is universal and contains a precise sequence, as well as the colours used are red, amber and green. The particular sequence is very of great help for people who are colour blind.

The traffic lights which can be most commonly in use incorporate a set of three lights, red, amber and green. They sometimes are set up in a vertical position using the red light at the top, amber light in the centre and the green light at the bottom. In some countries traffic lights might be set up horizontal.

When a vehicle approaches a set of traffic lights as well as the light on the signal is red, it becomes an indication to that vehicle to halt. The amber light points too the lights are planning to change, either to red in order to green depending on which world you are in. When the lights switch the signal from green it is signalling it is safe to proceed as well as the vehicle may continue its journey.

The variations inside the use of traffic lights will vary depending on the country and then any special needs for a specific intersection, for example special lights may used for buses, pedestrians and bicycles etc; or special rules for controlling traffic that happen to be turning in a particular direction. Some intersections can be quite complex and will employ any combination of these.

The first traffic lights were installed outside of the Houses of Parliament working in london, Great Britain in 1886 at the time looked like railway signals with semaphore arms and red and green gas lamps.

The modern electric traffic lights was a united states invention, and the first interconnected signal system was positioned in Salt Lake City in 1917.

The amount of time the amber light is illuminated may differ and in many places it is 5 seconds. From time to time it may be as little as 3 seconds which considerably decreases the time the driver has to react. These times generally vary in accordance with the set speed limit, and longer times are shown for higher speed limits.

Lights are used in other types of road signs including ' Slow Down' signs and fog symptoms which are illuminated when required, or in the case of the slow down sign they could be electronically activated because speeding vehicle approaches.
