Inductive and Radar Traffic Loop Detectors are Compared.

In today’s frantic society, most individuals are preoccupied with their busy work, and technology is advanced. Everything is easily accessible, and a slew of new inventions and equipment will meet people’s demands in various ways. Not everyone is aware of the loop detectors traffic; the loop detector can assist individuals in their hectic travels.

The loop detectors are primarily intended to detect vehicles. This technology is quite useful, as it allows you to track down more vehicle movement. Loop detectors are the most excellent solution on the market for detecting automobiles. People in their daily lives commonly use loop detectors.

Detectors of Inductive Loops

Modern technology is highly beneficial to individuals in various ways; these new intentional ways can alleviate people’s stress. Inductive loop detectors are one of the most commonly utilized sensors in traffic control management. The traffic application of inductive loop detectors is widely employed all over the world. This type of traffic detector operates mainly through electromagnetic communication or detecting devices. The alternating current might cause an electric current to flow across surrounding cables.

Advantages of inductive loop detectors
  • It works by sensing disturbances in the electromagnetic field using a wire coil embedded in the road. It is one of the most well-known systems for engineers, and it will also be incredibly cost-effective.
  • The inductive loop detectors traffic is a well-known technology globally, but they can also help provide basic traffic statistics at any time.

Radar Detectors for Traffic

For years, radar has been employed on traffic signals, which are widely used for vehicle detection. The radar can be used as an alternative for XYZ loops on a single approach for traffic detection.

All in one microwave system, it can detect the presence and movement of cars. This type of detector may also assist in seeing bicycles and stopped automobiles, which is one of the system’s key advantages.

The Advantages of Radar Traffic Detectors
  • This detector is one of the traffic loop detectors that have been approved for use in detecting the number of cars. This radar detector can detect very slow-moving traffic, allowing it to see vehicle movement quickly.
  • When compared to other detection systems, the radar detection system is less expensive and more valuable. The radar traffic detectors are fixed on a single pole, and the entire installation is completed in a matter of minutes.

  In Conclusion

One of the well-known inventions that are widely used all over the world is traffic loop detectors. With the help of the benefits listed above, you should better understand inductive and radar traffic detectors.

Learn About Loop Detectors

Learn About Loop Detectors

Loop detectors are among the most common sensors available in the market currently. They are widely used for detecting cars around gates, control barriers, intercom systems, ticketing machines, and boat docks. Loop detectors offer the most reliable ways to see vehicles in the current market. They work by detecting metal, so they are also found in places such as car parking lots, toll booths, and most commonly on the streets around traffic light signal points. 

Modern loop detectors work quite well and are also easy to install and troubleshoot, making them the most common choice for vehicular detection. 

What Is Loop Detection And How do they work?

Loop detection works by using an induction loop (usually made of copper wire) located on the road surface. This wire is connected to a loop detector, creating a magnetic field in the electrical coil (a metal stick). This may sound like it doesn’t make much sense, but it’s pure physics, and the electromagnet used in these detectors are pretty easy to understand. When a vehicle passes over this detector, the magnetic field is disturbed by the vehicle’s metal, thereby triggering the sensor for identification. 

Using this detection system, loop detectors work in places like fences, industrial and mansion gates, parking booths etc. The most commonly used loop detectors are inductive loop detectors used under roadways around traffic signals. In traffic signals, when the vehicles stop over these detectors, the electromagnetic field change is noted, and this detection shows up on the traffic light control system. 

Generally speaking, a smaller size car causes a higher range of frequency disturbance in the loop detectors than a vast, heavy truck. This is because the metal undercarriage of the smaller cars comes closer to the loop detectors. Think of a compact sports car with an undercarriage that is exceptionally close to the track’s surface than a huge utility truck that is at least a foot above the ground, so the frequency trigger is more significant with a smaller car. 

Size And Proper Installation of Loop Detector

The size of loop detectors varies according to the size of the road or driveway and the estimated vehicular size that would pass over the loop detectors. 

Installing the loop detector properly is of utmost importance as this will ensure proper operation and trigger detection. Generally speaking, all loop detectors work on the same physics principles and offer more or less the same reliable results considering they are correctly installed. Some materials and features may vary from brand to brand, but installation is pretty similar. You should make sure to follow the proper guidelines mentioned by the specific brand. 

The few features you need to bear in mind for successful installation of loop detectors are as follows:

  • The copper trigger wire needs to be placed at least 1 inch under the road, but make sure the wire is not buried more than 6 inches deep. This wire also needs to be placed securely with a backer rod with proper use of sealant. 
  •  When installing, make sure to cut the loop detector wire at an angle of 45 degrees rather than 90 degrees. This will ensure a reduction in wire tension and erosion as these can result in false triggers, causing you to do repeated servicing for your loop detectors system. 
  • To avoid further false detections when using multiple loop detectors within the same installation range, make sure to set all of them in different frequencies. For example, if one is set with a free exit loop, make sure the other is a reverse loop. Doing this will help you avoid cross signalling triggers which often result in false detections.
