Tracing the History of Traffic Lights & Other Important Aspects

If you’ve ever came across a busy intersection without any traffic lights, you know how frustrating it can be for everyone involved. In these cases, unless there is a police officer regulating the traffic, it’s close to impossible to get on your merry way without honking at least a few dozen times. Therefore, it’s safe to say that traffic lights, no matter how much we hate waiting for the green light, are something we should be very thankful for.

They’ve been around for about 150 years, believe it or not. They were first installed in London, however, they weren’t automated. Some years later, in 1910 be to exact, the first automated traffic lights were patented in the US and only 4 years later the first electric traffic signals were set up in Ohio. We’ve come a long way since then, and traffic lights can now be found in the most remote places on the planet.

They’re safe for the environment and emit strong brightness, which makes them visible in foggy weather. LED traffic lights are also resistant to mechanical shocks and are extremely durable, which makes them perfect for outdoor conditions.

They find uses in many other industries as well – there are a lot of private sectors that benefit from them. Basically any business that has many vehicles going in and out of its parking spaces can have their operation efficiency increased by implementing traffic lights. For instance, a parking lot can feature traffic lights and signal drivers whether there are available spots to park on them or not.
