Hi Ticker, maybe try first to disable the AngleChecker with --ignore-sharp-angles. Next, I'd try to disable the compacted format in RouteNode, search for useCompactDirs. The original code in tweezeArcs() was written at a time where the encoding of the heading values was completely misunderstood.

These were some of problems that --adjust-turn-headings with code in RouteNode.java::tweezeArcs() was designed to solve. I'd like to have a go at reinstating it and tweaking it a bit to see if I can overcome some of the problems mentioned in some of the threads, eg http://gis.19327.n8.nabble.com/Possible-problem-with-adjust-turn-headings-td... http://gis.19327.n8.nabble.com/What-is-the-idea-behind-adjust-turn-headings-... before it was removed in r3649. I'm considering putting the code in imgfmt/app/net/AngleChecker.java Case 2/ can have further complications because OSM doesn't provide information when you have to give way as you turn to stay on the same road. Another pop-up I'd like to see is the minor road you wish to stay on is intersected by a more major road and you have to give way. Does anyone know if there is any way of triggering this? Ticker
