Duplicate ways - should be removed

Hi there!
Trying to remove duplicated ways in Belgium, I found some strange situation.
Could somebody help me to understand what means tags of this way http://www.openstreetmap.org/browse/way/155337190 ?
This way is overlaying the another way http://www.openstreetmap.org/browse/way/31453123 .

Thanks in advance.

I have the impression that the mapper tried to create the route for a bus (shuttle). Instead of creating a relation he just created new ways over the existing ones.

I’ll forward your question to the mailing list, which is more active (if you allow me to do so).

Thanks. Of course - You can forward my question, we all need to make maps to be correct and good quality.
There are a lot of another duplicates in Belgium, we use validator at http://peirce.zkir.ru/qa/BE-WAL and http://peirce.zkir.ru/qa/BE-VLG

Thank you in advance!

Another user had the same idea as me: it should have been a relation to represent the busroute.

Did you try to contact the user that mapped that way ?
