Traffic lights are an essential part of our transportation infrastructure. They help control traffic flow, direct vehicles and provide information about road conditions to drivers.
The cost of installing a new traffic light depends on several factors, including the location, traffic and the size of the intersection. Usually, the entire system costs $250,000 to $300,000 to install.
Traffic lights have a hood or visor that houses the LED light sources and an electronic controller. They also have a lens that's made of plastic or glass, depending on the manufacturer.
A traffic light can weigh anywhere from 30 to 50 pounds, depending on its material. Most modern traffic lights are made from aluminum or polypropylene.
The lenses of most traffic lights are standardized in size, color and shape to make them easier to see. They range from 8 to 12 inches in diameter.
The main purpose of traffic lights is to stop traffic congestion from forming. They prevent a lot of accidents and keep people safe on the road.
When traffic lights are installed properly, they reduce the amount of time drivers spend waiting for a green light. Motorists can expect to save an average of $5 per hour.
