A Comprehensive Overview of Loop Detector Traffic

by | Mar 26, 2021 | Automotive, Business, Services

This article fundamentally discusses the loop detector traffic and its significance. Loop Detector Traffic are metal detectors with their antennas, loops of wire spread out just below the streets’ surface. The loop detectors traffic serves to trigger traffic signals when vehicles are overhead.

Detection augments the efficiency of traffic flow. A small street that crosses the main street can, for instance, procure a green light only when a vehicle is waiting. A timer need not have to prevent traffic on the main street every minute or two, whether or not anyone is waiting in the side street.

A former type of loop detector traffic was a pressure-sensitive device embedded in the street. From approximately 1970 onwards, loop detectors traffic was significantly in use and has become practical with transistorised electronics. 

Pressure-sensitive detectors responded well to bicycles, but many loop detectors traffic were not sensitive enough to detect bicycles in the former primitive years of their inception. Research and study revealed that these endure and delivers suggestions both for new installations and for retrofits.

Research has established that sensitivity is necessary to detect bicycles. Detection was easily achieved with the apt setting of the electronics in the signal control box, but raising the loop detector traffic sensitivity would lead to unnecessary triggering by a vehicle in the next lane. Most commonly, a vehicle turning light and exiting an intersection could very well trigger a signal. Installation crews addressed this peculiar difficulty by turning the sensitivity down as low as possible while still detecting a passenger car in the lane directly over the actuator loop.

The loop detector traffic so altered and adjusted, would not detect a bicycle and most frequently not a motorcycle. This deficiency stimulates, in some cases, forces- bicyclists and motorcyclists to run red lights. Most bicyclists, possibly major motorcyclists, do not comprehend why lights stay red, leading to more widespread disrespect for traffic signals. Entering into an apt intersection on the red can is as well-known as resulting in crashes.

Loop Detector Traffic

Equipping the loop detector traffic antenna more directional- so it responds much more prudently and durably to vehicles in the lane directly overhead than those in adjacent lanes. It permits the sensitivity to be raised so that bicycles and motorcycles are detected reliably.

One of the most visible components of any smart city is the traffic management system. With loop detector traffic, the behind-the-scenes work can be executed to power these systems. Think of loop detector traffic being the seven-eighths of the iceberg under the water. While the one-eighth above the water receives all the attention, it is the loop detector traffic below the water that acts as a foundation to hold it all up. Loop detector traffic work silently and efficiently in the background to deliver the foundational data for all the neat things one can do in traffic management and smart cities.

Conclusion:

Thus, Loop Detectors traffic is relatively more straightforward as a system. Still, at the same time, it is imperative to arm yourself with the knowledge and awareness of how it works and how the pieces interrelate. There is no question about a problematic installation that can become an extremely frustrating scenario. Still, if you break it down to basics, it can be solved more efficiently.

  • Deploy a preformed loop detector traffic before the pavement is installed
  • Employ a saw-cut loop detector traffic when the pavement has already been installed
  • The loop detector traffic must be buried no more than 2″ below the asphalt or concrete surface.
  • Replace any loop detector traffic wire that has nicks or splices in the insulation
  • Connections to the loop detector traffic, the loop and the extension cable must be soldered.
  • The frequency decreases as the temperature of the loop detector traffic increases.
  • The frequency increases as the temperature of the loop detector traffic increases.
