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):
123617668315712:error:1000012e:SSL
routines:OPENSSL_internal:KEY_USAGE_BIT_INCORRECT:third_party/openssl/boringssl/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.
Regards,
Thorsten

Hi Ticker,
I'll have a look at the patch during the next days. Please ping me if I
didn't react until August 20.
Gerd

Hi Gerd
Patch attached that, where possible, keeps ~straight roads unchanged
and widens
the sharp angle on the other road.
This should fix the particular example and generally be better,
although it is
difficult to test.
I try and note where I get incorrect turn instructions and later work
out why
and, since the arcHeading_v2.patch in Oct 2020 I haven't found any that
are
fixable; I couldn't find a solution where the major road continues at
an angle
and the minor side road continues straight on.

Hi Gerd
I presume you are just changing SHARP_DEGREES, leaving
COMPACT_DIR_DEGREES
alone.
In this example the arcs on either side of the sharp angle have the
same
priority (class/speed) so there isn't an obvious one to adjust so the
logic
adjusts both.
Also in this example, and very common, is a side turn off a basically
straight
road and the proportions that each arc is adjusted isn't ideal in that
the
straight road is bent slightly more than the side turn is adjusted.
This could be spotted as a special case: when there are 3 arcs and the
available
angle on one side or the other (initial value of deltaPred or
deltaNext) is
close to 180 degrees then just the other side should be adjusted.
Maybe the 3
arcs doesn't really matter as long as there is sufficient space to
adjust the
other side.
I'll do some experiments.
