Hi Gerd
will do so tomorrow - cannot get onto my server since 2 hours (if I still cannot get on the server I will compile locally on Friday).
As for the mail - yes I read it and replied in here.
I think the order for most would be the opposite - throw away the first roads, not the last! Usually you would first put in routes, bridges and so on into your map - then maybe lines just for visualisation - all with continue, and then finally put in the road itself without continue.
For my maps the best approach in doubt would be:
1. check if one segment is completely double (same type - fully covered by the same type).
2. Throw away 0x13 (I use this invisibly for routing)
3. Throw away those roads created first if still needed.
