Civilians have a fascination with traffic lights. The light will turn green, and you are on your way much before you can put your morning coffee back in the cup holder. Most lights do not have this technology. Some tout the technology, and it works extremely well to effectively in keeping control of traffic through intersections.

Vehicle detection loops accomplish a few things:

  • Point out when a vehicle is stopped at a light
  •  Ensure if traffic is stacking up at a light
  •  Take control of the light duration
  • Vehicle Detection Technologies

Globally, there are dozens of traffic loop detectors technologies being utilized, from lasers to rubber hoses and everything in between. One of the most commonly used vehicle detection systems is an induction loop.

Other Traffic Loop Applications

The traffic loop can be used in a variety of other applications, such as:

  • Audio: An induction loop aid in assisting those who use hearing aids.
  •  Metal Detection: A traffic loop detector is used in some metal detectors, which stimulates the detector when induction changes due to the metal being on the item or person being passed through.

The function of an Induction Loop 

As the name refers, the inductive loop functions by monitoring a change in induction. What’s more, if you were to take the inductor out of the traffic loop detector, you would have a flashlight. The induction in the loop is created by the building and releasing of current. Now the question is, what releases the current in a vehicle induction loop? When a vehicle slows down to a stop at a light, they open the induction loop that’s buried in the road, resulting in a change in induction. This makes the signal to the traffic light that there is a vehicle stopped at the light. The capacity of the induction loop is calculated in two ways: The number of coils and the core, I.e. what the coils are wrapped around. 

Understanding Induction Loops via Electromagnets

An electromagnet is relatively easy to understand. It is made up of a length of wire, typically copper wrapped around a metal stick. These two kinds of stuff may seem like a jumbled mess in a pile on the floor, but when you introduce electricity, a magnetic field is thus created.

Why Choose a Vehicle Induction Loop

You can trust an induction loop if you’re searching for an apt traffic loop detector. It’s one of the market’s most widely used traffic control products. It’s long-lasting and reliable and automates most traffic control via intersections and stop lights. The induction loop system is a great choice when it comes to time and money.


A busy intersection can result from a lot of traffic build-up. A big challenge for cities, towns, and metropolitans is the widespread growth of vehicle use. As vehicle use grows gradually, traffic becomes a bigger burden on the area. A great way to reduce this burden is to automate traffic lights through the system of traffic loop detectors.
