Comment on How does an automatic road barrier decide when a vehicle is coming?

  So a large wooden horse could slip by without detection

    If the large wooden horse is full of men in metal armor, purely hypothetically speaking, would the loop still not pick up the large wooden horse?

      Technically speaking it would pick up the men in metal armors, not the wooden horse per se.

      But the barrier would lift for the wooden horse full of men in armor indeed.

        Depends on how high on their horse they are: They might be too far away to trigger the sensor.

  This, it’s like a metal detector but, bigger. Temporary boom gates might use infrared motion sensors like automatic lights.

    It’s bigger in overall structure size, but isn’t really that big itself. It’s just a wire loop, they can be installed into existing roads with minimal effort - they just dig a narrow trench and then seal it up, it doesn’t require more tarmac.

  Huh, so that’s a completely new concept I’ve learned today. Time to do more reading. Thanks!

    Check the road in front of the gate. Those loops are usually installed after the asphalt so there should be a loop patched up with tar a bit smaller than a footprint of an average car.
