The Independent discloses that the site of every speed camera is to be disclosed together with accident figures before and after its installation, coupled with the amount raised in fines and other 'punishments'.
Having been on a Speed Awareness course recently, one statistic which was released to those of us attending was that in the Thames Valley Police area - which covers Berkshire, Buckinghamshire and Oxfordshire - at the end of 2010 there were just 297 fixed/static cameras and that, surprisingly, there were only 22 cameras, each costing approximately £25,000, which were moved between the housings, a decision taken on a number of factors such as accidents etc. The figure for hand-held cameras and those situated in vans, was mentioned, however unfortunately I cannot recall the statistics.
It will be interesting to see if the number of cameras has increased, depending of course on the period the released statistics cover. Bearing in mind the number of actual cameras available it is obvious that some housings are inoperative* during the course of a year, which would lead one to question the statistics that are provided.
* As an example of this, there is a camera on the A338 twixt Gove and Frilford that is obviously empty at present as just last Tuesday a police van with darkened windows (darkened windows being a sign that it was a 'camera van') was parked by the side of the road just yards from the fixed camera.
