Hi Gerd In theory yes, but messages in various forums seem to suggest that creating ways with more than 2000 points causes problems, and the feature in question has been chopped into multiple ways of ~1700 points. I estimated the maximum number of points before limits might be exceeded is 16200. This case is a bit pathological. I doubt if there are real roads this long without change of name/speed/class Ticker On Mon, 2020-08-03 at 19:52 +0000, Gerd Petermann wrote:
Hi Ticker, whatever Roadmerger does, the same data may be in OSM. There is code in Styledconverter to split roads and also later down the chain.
Problem should be fixed there. Cannot help more until I am back. Cioa Gerd

Hi Gerd
I was thinking the problem was in, or at least could be solved reasonably easily in MapSplitter/MapArea. However this is too late because all the logic relating to splitting/merging roads and keeping track of highway ids/counts/restrictions/etc happens in StyledConverter. All MapSplitter does with roads with lots of points is to put them in a subdivision on their own.
The simplest way of fixing this is to stop roads being merged if the results probably won't fit into a subdivision. It isn't an exact calculation because the line smoothing filters haven't been run yet.
I've attached a patch to do this.
