At various intersections around the city I see, in the roadway, three circles the size of dinner plates spaced a foot or two apart. I read somewhere that these are sensors for bikes but I'm not so sure. Does anyone know just what these are for?
As far as I know those are to mark the magnetic strips under the pavement that sense whether a vehicle needs the light to change or not.
If you look at intersections with stoplights you will notice as you approach 'cut outs' filled with black rubber in the pavement.
On a motorcycle you want your engine to be directly over one of these rubber cuts so that hopefully the sensor will initiate a light change.
Unfortunately these don't always work... I've heard of people putting magnets under their bikes for this but again there are people who say it works and people who say it doesn't.
I have also heard of people putting their bike in neutral and putting down the kickstand onto the sensor line.
Some lights just won't change for motorcycles though, no matter how long you wait/ hover over the sensor
Are you talking about red or beige plastic discs? Maybe 3" or so across with no cuts for wires.
You might be talking about a product for road inspectors, they are imbedded at grade on roads and sidewalks and will turn red or pinkish when the surface temp drops below freezing.
I'm trying to find a picture but so far no luck.... they might be what you seeing???
Thanks snecro. I thought I'd heard that somewhere. So I guess the idea is to sit directly above the "dots"?
That info will probably help a lot of bikers!
I thought this thread was about something else. Since some road marking pro's may be still reading this... here's another question for you.
I originally was hoping to see a question about those little turtle shell looking humps they've been putting in the middle of lanes around Peel/Halton. What are those? I assume car counters (instead of the tubes across the whole road) but is that what they are?
OP.. I have no answer for your original question, I'm gonna go with what they said.
