Following up to Adrian Tupper
they are all 30 round here, not that that's the point. The cameras I pbutt on one regular daily run are thusly several on 50 dual (was 70 until recently,so you can picture the layout) one on steep downhill 30 (no particular hazards) none outside schools, shopping centres or junctions where low speed would be good. I'm inclined to conclude they are placed where most people speed, rather than protecting hazards to pedestrians. The downhill 30 seems designed to catch out relatively "innocent" people who fail to brake enough for the downhill.
I might as well have a rant about the one on the A303 while I'm at it Picture up hill two lanes, down hill one lane (crawler lane type layout) . At end of stretch of uphill 2 lane a blind brow. If there's one spot in the whole country where high speed is safer, its there. Overtake and get back in well before the brow in case a lunatic is in wrong lane or there's some other hazard over the hill. so what do they do? Put a speed camera on the safe bit so people end up still overtaking when they get near the brow. no doubt they noted accidents at that spot so concluded a camera would cure the problem. A nice piece of concrete island would cure it much better. the camera just has the effect of stooping overtaking and moving overtakes somewhere less suitable. -- Mike Reid
