    Trigger GREEN Traffic Lights

    There's no question that a permanent magnet will create a *different* induced current in the induction loop than that produced by induced eddy currents in the conductive material of a large vehicle, but it certainly isn't nonsense. As your scooter, bolstered by permanent magnets, drives over the induction coil, the coil *will* see a changing magnetic flux which induces a current. When your scooter stops, the induced current will also stop. That should make your scooter look pretty much like any other vehicle that enters the loop and then comes to a stop (unless the tripper is designed to look for the continued presence of a stopped vehicle through the use of alternating current - I don't know if any are programmed that way). I suspect this idea would work for pretty much any traffic...see more »There's no question that a permanent magnet will create a *different* induced current in the induction loop than that produced by induced eddy currents in the conductive material of a large vehicle, but it certainly isn't nonsense.

I suspect this idea would work for pretty much any traffic light, because they can't be programmed to be terribly sensitive to any particular signature - different vehicles will all create slightly different induced current signatures.
