In a village near me there is a lamp-post in a 30 mph zone which has a
rectangular metal "tube" about 1 foot long by 6" square which is pointing
straight down at the road surface by the post. There is also another
device alongside, again pointing at the road. There are no road markings
like you get with speed cameras. I presume the larger device is a camera
and the smaller one is a light. The cameras are angled so steeply that
they could not see the number-plate of a car. There is also a box on the
lamp-post which may be some form of control module.

Ignore the curvature of the lamp-post: it's distortion from the lens in my
dashcam: I had to wait until I was close to the lamp-post to get the
largest image, and that's when it's on the edge of the frame where
distortion is greatest.

Any ideas? I'm intrigued.

(the tree by the lamp-post was a bit smaller and was in full leaf in
September 2011).
