So just something that’s been on my mind. At my workplace there’s an automatic road barrier that lifts up and down when vehicles arrive. However, it’s not used for a carpark system when people wave their tickets or something. It just goes up and down when a vehicle shows up.
However, it sometimes goes up for when say a pushcart is being rolled over whereas it wouldn’t for a guy pushing a bin.
So tldr, how does an automatic road barrier decide that yes, a vehicle is coming, and therefore opens up?
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.
