[OSM-talk-be] intersection looks very wrong -> use PICC with JOSM

[Jakka]

Thx for the reply,
Was working on it this WE several houres allready and saved it offline. 
Will checked again 'with after an good night sleep) and hopefully I can 
uploaded all changes at once.
The PT relation will all be destroyed, could not keep the highway with 
them on it.
