Hi WanMil, in addition to my previous post: A completely different approach would be to add or change a point near the crossing (in RoadMerger) so that the bearings calculated in RoadNetwork are fine. In that case we just have to store one bit in the Coord instance to tell tweezeArcs() that this point should not be changed. The additional point(s) could be very close to the crossing and maybe removed later. Gerd

Hi WanMil,
I think the code for --adjust-turn-headings in RouteNode.tweezeArcs() looks rather similar to that in RoadMerger, and maybe will not work as well in combination with RoadMerger as it assumes that two arcs with the same road (OSM id) are building the "main road":
// the code tries to detect a pair of arcs (the "incoming" // arc and the "outgoing" arc) that are the "main road" // and the remaining arc (called the "other" arc) which is // the "side road"
I got the impression that RoadMerger also calculates the required data (angles etc). It would be great if RoadMerger could store the information somewhere so that tweezeArcs could use it.

Ok, do you have an idea how to store the required information?
