<div dir="ltr"><div>okay - I tested around a bit more. Using v4 patch and cycle-map option - there was again rather no improvment.

Hi all,<span class=""><br>
<br>
attached is v4 of the patch.<br>
Changes:<br>
1) The option --x--fix-sharp-angles is gone.<br>
2) A new option --x-ignore-sharp-angles can be used to disable<br>
the code that enlarges sharp angles<br>
3) The option --cylcle-map is now documented (not in detail,<br>
as I still work them out). Please try if the option improves routing<br>
in cycle maps. It allows changes up to 112° instead of only 45°.<br>
4) known errors were fixed:<br>
- use sum of speeds<br>
- take into account that values maybe rounded when calculating<br>
the new heading(s)<br>

I have tested the patch and I find it doesn't avoid the "spurious instructions to "keep right/left" when the road doesn't actually fork". My test case is a route from SW to NE along A-471 (<a href="http://www.openstreetmap.org/#map=12/36.8685/-6.1225&layers=T" rel="noreferrer" target="_blank">http://www.openstreetmap.org/#map=12/36.8685/-6.1225&layers=T</a>) where I get several unnecessary keep right/left instructions at crossings with sharp angle links leaving A-471, such as the one at <a href="http://www.openstreetmap.org/#map=18/36.77762/-6.27642&layers=T" rel="noreferrer" target="_blank">http://www.openstreetmap.org/#map=18/36.77762/-6.27642&layers=T</a> The number of these unnecessary instructions is lower than without the patch (6 vs 9).<br>
The map is produced with a general purpose style, not a cyclist one.<div class="HOEnZb"><div class="h5"><br>
