Not sure where you are based, shzl400 but the residents of Ewelme and Woodcombe (Forest Hill bypass) have been in contact with the Council for years re speeding traffic and congestion, ever since Peter Dawson was the local councillor and the Forest Hill Steering Group was in full flow. Speed and traffic are not always mutually exclusive by the way. A 20mph zone was one of the requests due to the reduced impact on traffic casualties were a child to be hit at that speed as opposed to 30mph.
We were put forward for funding on several occasions but never managed to get it due to the actual lack of fatalities. This is one of the major pedestrian routes to both Horniman and Fairlawn schools and hence is an increasing concern for local people.
There were several incidents including walls being demolished at the junction by speeding cars, cars being damaged, and lorries shedding their loads after speeding and then having to brake suddenly. Frequently lorries would just drive off leaving their rubble etc blocking the road. To witness some of these large vehicles hurtling down the hill in excess of 30mph is actually quite scary. To get a 20mph zone is not the end, but the beginning of concerted action to improve the safety and enjoyment of residents on these particular roads so yes, requiring enforcement will be next on the agenda.

I haven't looked to see how HOR itself is affected by these proposals but this is another nightmare for children walking to and coming from school due to traffic numbers, narrow footpaths, speeding and just sheer bad tempered early morning driving. I know some people just won't walk on the eastern side of the road for that reason but prefer to walk on the slightly raised part on the other side.
