AFAIK ...
the road sensors you see are operating on inductance, and detect only loop current change ... and not on weight/pressure/anything else funky.
As such, I dont believe they can calculate the speed of the vehicle passing overhead. For starters, they would need to know the length of the vehicle.
They cannot reliably determine the length of the vehicle by pulses either, since the inductive sensors rely on some ferromagnetic material moving into their field. This could include anything from rims to chassis rails ... so they cant reliably determine the wheelbase of a vehicle by this method.
Also, different vehicles have different numbers of wheels, so this also rules length determination out.
I do however agree, that it would be possible to trigger another speed sensing device, as they are just that - triggers, for the lights.
