20 mph zones

Over the past few weeks I've been out and about in most villages in the Cynon Valley. One of the themes thats come up time and time again is dangerous speeding in residential areas. On most streets there are families with young children who are frightened to let their children out to play. It strikes me that right across the Valley there is a strong case for designating a large number of residential areas as 20mph zones. There are enough distractions to keep children in doors these days, so we should be doing everything possible to ensure a safe local environment for children to play, and for all of us to enjoy - whether on foot, bike or in the car.
