<div dir="ltr">Actually it's even worse, in part there are three ways on top of each other. So actually I end up with 3 + 3 + 5 ways. Maybe ways on top of each other that share the exact same nodes should be joined before put into the map?

I did go through my style, and without this bug the style should create no more than 4 routable lines at most for a single street (yes this does not solve if there are two streets that get put on top of each other, because of super detailed mapping).

<br>
further thoughts about this: Up to now we concentrate on problems caused by rouding errors when OSM (~32 bit) coordinates<br>
are placed on the 24 Garmin raster.<br>
What about places where OSM data already contains overlapping highways?<br>
I think there is currently no code in mkgmap to handle this properly. Don't know if we can find rules to handle this,<br>
if not we should print warning messages, as it is likely to cause trouble.<br>
Overlapping can mean :<br>
* two different OSM ways with identical sequences of 2 or more nodes, e.g. a-b-c-d and x-b-c-y<br>
* two different OSM ways with identical sequences of 2 or more nodes, but in reversed order, e.g. a-b-c-d and x--d-c-y<br>
<br>
My understanding is that these are mapping errors, but as said before there is no code to detect this. There might be<br>
warnings, e.g. in the housenumber code.<br>
