I cross that intersection regularly as a pedestrian (brocki-land is just around the corner, my favourite source of second-hand bargains)....
It's a complete shocker, because the dominant traffic goes through manessestrasse into steinstrasse...but neither road seems to be 'dominant' to the other...and it's complicated by the fact that there are pedestrian crossings around the whole intersection, plus two bus stops...
quite honestly, I'm not really sure how I've avoided witnessing any accidents, because for every person that seems to know the rules, there is one that doesn't....
