What is traffic light and its function

Traffic lights, also known as traffic signals, traffic lamps, traffic semaphore, signal lights, stop lights, robots (in South Africa), and traffic control signals (in technical parlance) are important signaling devices that normally located on road intersections, T-junction, pedestrian crossings, and other locations so that it can be used to control the flows of traffic and reduce the occur of road accident. Beside that, traffic light also act as a safety device that appear on the road in vast majority of country in the world. Traffic lights are very important on the traffic safety management to maintain safety on road for all the pedestrians and drivers across the road. Increasing accidents and fatalities occur on the road have cause the growth of the traffic lights market, as traffic lights provide drivers control on road and improve the flow of traffic. Another factor that has driven the growth of the market is the improvement in traffic flow regulations by the respective traffic safety organizations by constantly upgrading and maintaining them and creating various pedestrian facilities, extra-street lighting, traffic signal modifications, and signage marking improvements. The operation of traffic lights requires sophisticated control and coordination to ensure that traffic flow is as smoothly and safely as possible and ensure that the safety of pedestrians and protected them when they drive or walk cross the roads.

TRAFFIC HOUSING

Traffic Housing, also known as Housing, traffic lamps, traffic semaphore, signal lights, stop lights, robots (in South Africa and most of Africa), and traffic control signals (in technical parlance), are signalling devices positioned at road intersections, pedestrian crossings, and other locations to control flows of traffic.

The world’s first traffic light was short lived. It was a manually operated gas-lit signal installed in London in December 1868. It exploded less than a month after it was implemented, injuring its policeman operator. Traffic control started to seem necessary in the late 1890s and Earnest Sirrine from Chicago patented the first automated traffic control system in 1910. It used the words “STOP” and “PROCEED”, although neither word lit up.

Traffic lights alternate the right of way accorded to users by displaying lights of a standard colour (red, amber (yellow), and green) following a universal colour code. In the typical sequence of colour phases:

The green light allows traffic to proceed in the direction denoted, if it is safe to do so and there is room on the other side of the intersection.
The amber (yellow) light warns that the signal is about to change to red. In a number of countries – among them the United Kingdom – a phase during which red and yellow are displayed together indicates that the signal is about to change to green. Actions required by drivers on a yellow light vary, with some jurisdictions requiring drivers to stop if it is safe to do so, and others allowing drivers to go through the intersection if safe to do so.
A flashing amber indication is a warning signal. In the United Kingdom, a flashing amber light is used only at pelican crossings, in place of the combined red–amber signal, and indicates that drivers may pass if no pedestrians are on the crossing.
The red signal prohibits any traffic from proceeding.
A flashing red indication is treated as a stop sign.
In some countries traffic signals will go into a flashing mode if the conflict monitor detects a problem, such as a fault that tries to display green lights to conflicting traffic. The signal may display flashing yellow to the main road and flashing red to the side road, or flashing red in all directions. Flashing operation can also be used during times of day when traffic is light, such as late at night in Malaysia.
