How do speed radars work? Not the ones that the cops carry but the ones that are inserted into the ground?

Ho do they they work? When are they active? How do they look like? Can you tell if you have been caught speeding? Where are they usually located. I live in Canada.

they measure the distance between two places and then use a formula to measure the speed...

ALL radars work the same way. Speed detectors in the ground are probably NOT radar. If they can detect a particular vehicle passing two points separated by a know distance, the time between reaching each point can be used to compute speed.
