Cllr, the shared surface schemes are great, so good for you for putting up with the flack in getting it through. They go some way to achieving the effects of the Dutch scheme, which, like PeckhamRose, I support fully. As a motorcyclist, cyclist, driver and pedestrian, I can see the benefit from all angles. Cameras would have to be placed on every exit of Barry Road, or they would only catch through motorists, and then only if they average the wrong speed for the the entire length of the route; it wouldn't stop them zooming up to 50, then crawling along behind the number 12 to get an average of 20. Again, too many variables. And if the sight lines are so clear on Barry Road, why the need for a camera-and-fine enforced 20 mph limit? Unless this is about making money?
