Traffic lights are a quintessential part of our everyday lives—especially here in the United States. They play a critical role in controlling the flow of traffic, able to turn the...
Using a combination of sensors and localized Wi-Fi signals, special smart traffic lights could temporarily connect right to a sufficiently advanced vehicle like an EV.
Obeying road signs and traffic lights is crucial for maintaining order and safety on the roads. These signals serve as a common language that communicates vital information to drivers, pedestrians, and cyclists, promoting a smooth and organized flow of traffic.

As cars became more ubiquitous, however, so did injuries and deaths from car accidents. One of the biggest issues was intersections, where cars, horses, and pedestrians tried to move through simultaneously. The solution was something that we’re all used to seeing today – the traffic light.
Traffic signals are automated devices installed at intersections and other key points on roads to control the movement of vehicles, bicycles, and pedestrians. They use colored lights—red, yellow, and green—to assign right-of-way and regulate the flow of traffic.
Traffic lights serve several important functions, including regulating traffic flow, reducing the likelihood of accidents, and increasing pedestrian safety. The three main signals on a traffic light are red, yellow, and green.
In their simplest form, traffic signals are a set of three lights facing each lane of an intersection. When the light is green, that lane has the right-of-way to cross. When the light is red, they don’t.
The most common traffic lights work on simple timers. Depending upon traffic levels at a particular intersection, the traffic light will cycle through green, yellow, and red at regular intervals to ensure a consistent flow of traffic in all directions through the intersection.
