Hi Andrzej,
It doesn't require much code to generate the pseudo roads, so maybe it is something for a special option.
Would be nice, if you preserve this code. Maybe even for all addresses, not only for addr:place? But actually I can extract addresses form OSM sources, parse them, convert to roads and get the same result. Either way, I'm glad, that we have found what works and what has to be avoided.
Okay. Let's first sort out how to fill the address info.
Although the wiki says that either addr:place or addr:street should be used I see many nodes with both.
IMHO use addr:street and ignore addr:place. Most probably addr:place is incorrectly set instead of addr:city, which you get from other data anyway.
OK, I'll do some statistics to find some good rules. My idea is to collect the numbers with equal addr:place tag. If there are not too many duplicates in different positions I assume that the place name should be used for the address and addr:street should only be used to identify the right road. That's what I am now trying to code. Gerd
