Yes I understand rhsdunlop, it seems to me most of the cutting through traffic leaves Devonshire by going up Ewelme, Benson, Tyson, Dunoon Rd with a little of it going along to the far end of Devonshire and vice versa in the evening. Also I notice a lot of cars leaving Honor Oak Park by going down Hengrave Rd only to rejoin Honor Oak Park ( or is it rd I cant remember) where Devonshire joins it, presumably as they hope the queue is shorter, so any scheme could involve all these roads. There are a lot of configurations from no right turns into Devonshire to blocking off some of these roads where they join Devonshire or at the other ends, all would stop cut through traffic but make some local residents car trips more inconvenient, but I think a consultation to find out whether the inconvenience for some residents who use their cars a lot would be out weighed by the benefits to those residents as well as others who do not use cars a lot or at all would uncover the majority feeling on the matter.
