Traffic Lights and Signals
Traffic lights are devices that allow for alternating flows of traffic. They signal to drivers when it is time to slow down, stop, or go. They help to ease traffic congestion in highly traveled areas.

What do you do when a traffic light is red with a green arrow to turn right?
A right turn is protected here, and no stop is needed.
What situation caused the traffic light to its birth?
The traffic light was born out of the need to manage increasing traffic in urban areas during the late 19th century. As cities grew and horse-drawn carriages, and later automobiles, became more common, the resulting chaos at intersections necessitated a system to regulate vehicle and pedestrian movement. The first electric traffic light was invented by Garrett Morgan in 1923, designed to improve safety and efficiency on the roads. This innovation aimed to reduce accidents and streamline traffic flow.
Why red light is used at traffic signal for stopping the vehicle's?
red color is have more visible sense. we see the light red color in much more distance compare to the other lights. Also red color will not affect or invisible due to some natural causes like rain, storm, dust, mist, etc.
Which came first traffic lights or roundabouts?
Traffic lights have been in widespread use since the 1920s. Roundabouts, in their modern form, were developed in the 1960s. There were circular road junctions since the early years of the 20th century, but the rules and conventions governing their use were markedly different from modern roundabouts.

Who should obey a traffic light?
Anyone driving a vehicle or riding a bicycle should obey a traffic light.
What are basic principle of working of decorders in traffic light controller?
Decoders in traffic light controllers convert binary inputs from sensors or timers into specific output signals that control the traffic lights. Each binary input corresponds to a particular state of the traffic light (e.g., red, yellow, green) based on predetermined logic. The decoder activates the appropriate outputs to ensure that only one signal is illuminated at a time, following the traffic rules and ensuring safety. This systematic approach allows for efficient and safe management of traffic flow at intersections.
