What is a Traffic Light?
Traffic light according to wikipedia is a light that controls the flow of traffic installed at crossroads, pedestrian crossings (zebra crosses), and other traffic flow areas. These lights indicate when the vehicle must run and stop alternately from various directions. Traffic regulation at crossroads is intended to regulate the movement of vehicles in each group of vehicle movements so that they can move alternately so that they do not interfere with each other between existing flows.
Overall, the way traffic lights work is based on the ATCS system. This system determines how long a green light is on. The duration of the green light is based on the density of vehicles that occurred at that time.
A Brief History of Traffic Lights
The first Traffic Light itself was first made in 1868 in London. The manufacture of this lamp was made because at that time there were many motorized vehicles. Traffic Light itself at that time was still two pieces, namely red and green. Three years later, Traffic Lights were banned by the London government. Just then, one of the Traffic Lights there exploded, injuring one of the police officers not far there. Some time later, a new model of Traffic Light was made with a 'stop' and 'go' sign. In the following years, Traffic Lights also experienced developments, to become what they are today.
