Hi Felix, if your style interprets a tag like a oneway=yes you should add that tag. This might prevent problems caused by the RoadMerger, which might reverse lines which are not oneways. If you find or set oneway=-1, the current implementation will reverse the way. If you add multiple routable lines for one OSM way, one with, one without the oneway tag, you will see unpredictable directions if such a way is modified by the WrongAngleFixer and the type is direction dependent. The WrongAngleFixer assumes that the points in all ways with the same OSM id are equal, so it optimizes one way and copies the points to the others. This will fail if they have different oneway attributes. If you think this could be the cause of the problem, I should be able to provide a fix.

I think in 99% of all cases - cycleway:left and cycleway:right are used on streets which feature oneway=yes... less often oneway=-1 and even less often no oneway at all. Streets with oneway=yes are fine. I'm talking about no oneway tag from OSM data at all, or oneway=-1 set in style (but no oneway from OSM data) or no oneway at all. Only on those there are problems - so you're not likely to notice them I think.... On 25 April 2014 00:39, Minko <[email protected]> wrote: Yes I render cycleway:left and cycleway:right too. And as you say, they are always on the wrong side on the GPS. Interesting to know that Garmin uses asymmetric lines independent of the road direction. If we only could find out how they do this...
