Hi Thorsten
Is the problem still with node https://www.osm.org/node/27550903 and
ways
36138336 / 144732811
Yes. That's one.
Else see below.
I've loaded this example and looked at the angles before and after
adjustment
with my patch. From the south the way enters the node with heading
161.6 and
leaves with heading -16, giving an angle of 178.6 (almost straight).
The other
way leaves with heading -32.4, giving a sharp angle of 15.4 degrees
that the
logic will want to increase.
After the adjustments, the main way isn't changed and the other way is
given a
new heading of -63 degrees.
In compactDir format the main way enters in seg 7 and leaves in seg 15
(direct
opposite) and the other way now leaves in seg 13 (a clear segment
between the
other exit). This, I thought, would be enough to get the turn
instruction on the
correct road.
I've forgotten how some of the forward and reverse arc stuff works and,
if there
is still a problem, I need to re-understand it to make sure that the
manipulations that we do to the angles at a node make sense for all
routes
through it
I don't know anything about the format.
Is there somehow a flag what is the main road, or is this navigation
instruction purely based on the degree of the turn?
Because, I have more similar situations like here:
https://www.openstreetmap.org/#map=18/49.43041/10.99213
If you go from north to the south and have to turn right no instruction
is coming, if you have to go straight forward, a "turn left" is coming.
Difference to the point above is, that the main road is make a turn
right and the straight forward is a new, smaller way.

Hi,
trying from another email account, with the other I always get an
error
when trying to send to the mailing list:
TLS Negotiation failed: FAILED_PRECONDITION: starttls error (71):

l/src/ssl/ssl_cert.cc:431:
I tried the patch from Ticker, it fixes routing problems with sharp
angles for me,
where previously Garmin devices would avoid the Junction.
But it does not fix the wrong turn instruction for me.
