One of my fave topics. I have been writing to the Highways Dept. about this crossing for years and always get the same kind of answers as Shara. My last suggestion to them was to add proper rumble strips either side of the crossing point to slow the traffic down. I have seen this done elsewhere to good effect but they did not respond to this suggestion. I have tried to involve local councilors but they seem not to be able to assist.
I may end up being the martyr as I now tend to grow impatient after around a minute or so and cross anyway .
When there were similar problems on Drakefell road in Nunhead a few years back (maybe quite a few) there was a local group who tried direct action and took to crossing slowly in large groups forcing the traffic to stop. If I remember correctly Lewisham gave in there as added refuges to assist pedestian crossing. Maybe we should have a FH version?
