I was at the pedestrian crossing at the bottom of Brockley Rise today and it seemed even worse to me. With this new phasing I could not see any point when it was totally safe to cross the Brockley Rise crossing. Maybe there was a small window in the phasing, but it was not obvious to me (we were there a while!) and without having superhuman powers of being able to view all the traffic lights myself, as a pedestrian you have no way of knowing whether traffic is going to stop or not. London drivers tend to only slow down for lights at the last minute.
I had three children with me and it was a little hairy to say the least, perched on a tiny pedestrian island, lorries and buses going past, trying to find a suitable gap in traffic when we could dash across, and relying on car drivers indicating which way they were turning (which from my experience as a driver round here i know they are not good at.....).
As a pedestrian that crossing has always been difficult, and now it is even worse.
