They definitely say sensors 'in' the road which would be inductive I think. But I am open to being corrected
The term "Safety cameras" is used above. In Greater Manchester the 20 limit couldn't be enforced by those involved in the Safety Camera Partnership. Fixed Gatso cameras aren't appropriate for most 20mph roads and the kind of equipment (usually LTI 20/20 laser devices with 500mm Tamron lens) that are used from the pavement by TPCSOs don't really work at distances of below 50 -100 metres, which again renders them unsuitable. The only real chance of prosecuting drivers is if they're followed by a Police car or bike. If any driver was clocked in a 20 zone by one of those they'd have to be drunk or certifiably insane not to see a big white 4X4 with blue lights on the roof, in addition to which, the Cops usually like to follow a vehicle for about one third of a mile at an illegal speed which increases the chance the following vehicle will be spotted giving the driver time to slow down.
