Lots of those twin rubber strip speed logging devices around Chobham, and a speed checking officer next to Jubilee High school in Addlestone today...
Best behaviour for now then.

Lots of those twin rubber strip ""speed logging devices"
These are the same two rubber cylindrical (1/2 thick?) strips you see (sometimes right) across the road that go to a counter box?
How can or are they used to say you are speeding?
I was under the impression that these did no more than count vehicles over a given period?
These don't last long in my neck of the woods what ever they do - someone will usually go over these with the brakes (hand or foot) locked up to break the rubber.
There has been a huge increase in the detruction of Gatso, Truvelo units too of late too.
It is now that bad in Yorkshire that there is a reward scheme in place that pays out if you report an offender & it leads to a prosecution.

They are used to monitor/survey a road and establish the number of vehicle and a profile of the speeds. The sensors are a known distance apart thus the recording had time and distance travelled by the front tyres. It is not rocket science. At a guess, either the area is up for a change in speed limit or a new speed camera perhaps a newer Red Speed camera which is at the top of a 5 metre pole to stop you climbing up and vandalising the lenses.

A 14" rim will give a considerably different speed reading to a 19" rim passing over the two rubber tubes.
So what happens if a vehicle with really large rims (trucks etc) goes over it - does it record a huge speeding offence!?
As far as I am aware these devices do no more than count traffic volumes.
As kids (heck that was a long time ago!) we used to stand next to the box (deprived childhood....) watching the numbers 'rack up' as cars went by and when there were no cars we used to jump on the rubber tubing to add our own ;-)
The only types of camera's that (I know of) to use a device that links it directly to the roads surface (via loops built in to and under the roads surface) are attached to Truvelo, Peek and Speedcurb.

Seen a few in Ashford. (Surrey). Must be a county initiative.

The rubber right across the road as described by Tron is for surveying and profiling, could be for many reasons, even just counting the axles to work out how busy a road is. They are temporary and placed between lamp posts normally.
The permanent "buried in the tarmac" strips in the road that are for speed checking are the DS2 system, always 3 strips (2 are no good) normally one side of the road only. Small post nearby that a camera van can "plug" into to start monitoring.
