Here's a handy item when stuck at a traffic light that doesn't change unless a large enough vehicle triggers the sensor:

I have a few lights like that. I usually just roll on through after a few cycles. Here are some tips on how to make it change

We have the ground sensors everywhere around here (Massachusetts).
It seems like a single magnet might not be enough to trigger them, though.

In addition, many police and fire vehicles have the "Opticom" system which allows them to control traffic lights as they're approaching the intersections so that they always have a green light.

Here many of the lights have a box with a cyclist symbol painted on the road. You position your bike in the box to ensure tripping the lights.

I don't think the magnet trick is very helpful. Some here tested it and it didn't work. If the lights dont trip on a bike we can call the highway dept and they will come and adjust the sensitivity.

I guess the smart planners live in Australia. That's a great idea.
