Vehicle detection loops play a big role in keeping traffic flowing smoothly and access control systems running as they should. These loops, often installed under or on top of roadways, are designed to sense when a vehicle is present. Once detected, they can kick off actions like opening gates, turning traffic lights green, or even just counting cars for data collection. Picking the right type of loop is key to making sure everything works as expected and lasts a long time. Whether you’re managing a busy parking lot or controlling access to a private area, the right loop can make a noticeable difference in how smoothly things run.
Types of Vehicle Detection Loops
Depending on the setup, you might need a loop that can be buried directly in fresh asphalt, one that’s mounted on the surface without cutting into the pavement, or one that fits into grooves cut into the road. Each type is built to meet different needs, so understanding what works best for your situation will save you time and hassle. Whether you’re dealing with heavy traffic areas or just looking for a simple setup for a gate, there’s a loop designed to make life easier. Plus, with the right installation, you’ll get reliable performance and avoid unnecessary headaches down the road. There are three primary styles of vehicle detection loops, each designed to meet specific installation and operational requirements:
Saw Cut Preformed Loops
Saw cut loops are installed by cutting grooves into the pavement, placing the loop wire within, and sealing it. These loops feature a continuous, non-spliced, machine-twisted lead-in made from polypropylene-wrapped copper wires. They fit perfectly in a 1-inch deep saw cut, reducing installation time and labor. The precise stacking of wires allows sealants to fully encapsulate the loops, enhancing performance and reliability. Saw cut loops are ideal for applications such as access control, parking barrier gates, overhead doors, gate operators, traffic signals, arming devices, and vehicle counters.

Direct Burial Preformed Loops
Direct burial loops are designed for installation in new pavement or under surfaces where cutting is not feasible. They arrive fully assembled and ready to install, encased in heavy-duty liquid-tight conduit to protect against external conditions like sharp stones, ground movement, chemicals, and weather. This design ensures flawless operation in projects involving paving, concrete or asphalt pouring, gravel roadways, and brick paving. Direct burial loops are suitable for parking barrier gates, overhead doors, gate operators, traffic signals, arming devices, and vehicle counters.

Surface-Mounted Loops
Surface-mounted loops offer a solution for situations where cutting into the pavement is not possible, such as post-tensioned concrete structures like parking garages. These loops arrive assembled and ready to install, with optional adhesive and lead protection included. Designed for use with automatic gates and common vehicle detection needs in the parking access revenue control industry (PARCS), they are fully compatible with all loop detectors. Surface-mounted loops are perfect for getting your gate up and running quickly without the risks associated with saw cutting.

Frequently Asked Questions
1. What is a vehicle detection loop?
A vehicle detection loop is a wire-based system that senses the presence of vehicles. Installed beneath or on the surface of roadways, it sends signals to trigger actions like opening gates, activating traffic lights, or counting vehicles for data collection. They’re a key part of access control and traffic flow management systems.
2. How do I know which type of loop to choose?
It depends on your specific installation needs. If you’re working with fresh pavement, a direct burial loop is ideal. For existing paved surfaces, a saw cut loop fits into grooves cut into the roadway. If cutting isn’t an option, like in parking garages, a surface-mounted loop is the way to go. Consider the environment and installation conditions when deciding.
3. What sizes are available for vehicle detection loops?
Vehicle loops come in a variety of sizes to fit different applications. Common dimensions range from small options like 2' x 6' for narrow driveways to large loops like 6' x 40' for wide entrances or industrial use. Be sure to measure the area you need to cover before ordering.
4. How long does the lead-in wire need to be?
The lead-in wire should be long enough to connect the loop to your control system. Options typically range from 20' to 250', depending on the distance between the loop and the control panel. It’s better to have a little extra length than to come up short!
5. Can I install a vehicle detection loop myself?
While some loops, like surface-mounted ones, are easier to install, others, like saw cut or direct burial loops, require special tools and expertise. If you’re comfortable with installation instructions and have experience, you might handle it yourself. Otherwise, it’s a good idea to work with a professional to ensure proper placement and functionality.
