Additional to below I want to mention that on a micromapping style a traffic_signal is placed one the pedistrian crossing or the stop_line. I even came across ones one the stop_line and an addition highway=crossing on the pedestrian crossing.
I am tagging direction=* for the direcion it faces. Together with the :lanes tagging you do not need any relation at all but could simply add the information on the node with :lanes tagging cu fly Am 18.01.2015 um 14:14 schrieb Tom Pfeifer: > Sorry but I'm sceptical about the scheme.
