Hi, see also http://gis.19327.n5.nabble.com/merge-lines-and-routing-tp5758913p5759595.htm... I wonder how this feature (overlaid line shows oneway direction) works with ways that are tagged oneway=-1 or oneway=reverse like this? http://www.openstreetmap.org/browse/way/6971216 or with the recent example from Minko http://www.openstreetmap.org/browse/way/6971876 The current implementation in r2606 works like this: 1) If the tag is found after style evaluation, the points of a road are reversed, but the points of the overlaying line(s) are not. 2) The merge-lines function connects lines without checking the direction. I want to correct the merge-lines method so that it doesn't connect oneway lines with opposite directions, so I have to make sure that all copies of a way have the same order of points. Will this change cause arrows showing into the wrong directions in existing styles? Gerd
