Hi Felix,

okay, I'll try to reproduce it.

Hi Felix,

great!
Do you have the log (created with me.parabola.imgfmt.app.net.AngleChecker.level=INFO
in logging.properties)
for this point and the one where the u-turn happens?

Nope - did not use that.

Does it also happen when you chose points which are not on the road
but close to it?

yes. Does not seem to matter.

Hi Gerd - okay now with patched and removing --adjust-turn-headinfs - plus adding both options I can see (vs before with adjust-turns-headings)

a) improvements on some tight turns (though not all tight turns)

b) less of those errors (though some still exist - but much less)

c) less erroneous detours on longer routes

d) valid only for Car/Motorcycle routing - often on the same route shorter times - sometimes longer as well though. The other profiles are much less affected here.

e) no difference at all in the maximum routable distance.

Once a strange degradation (again same place as yesterday):

Routing is alway correct on old map - but times are much slower. Old map nearly always had 1min

Only on Driving profile this bug happens (but no other - even Motorcycle is fine). Still 1min. However all other profiles (except walking) are between 26-28seconds.

Overall I would say it's a clear improvement (but yeah - those additional ways I guess would still be better).

Hi Felix,

if you get the same differences with the unpatched version and
--adjust-turn-headings turned on/off I see no miracles.

Ah - thanks. Well too strange I still got some differences...

I did not know and wondered why I found so little difference.

So more results in 1-3 hours - back to testing now.

Hi Felix,

got your mail with the pictures.
Please check:
You wrote that you used --x-cycle-map, but you did not mention
--x-fix-sharp-angles. I was probably not clear about these options.

If you did not also use --x-fix-sharp-angles you measured the effect
of the removal of the --adjust-turn-headings option, as --x-cycle-map
on it own has no effect with the patch.

Reg. testing: Please try to route to points close to but not on the road.
Maybe this avoids the u-turns when the Garmin algo reaches the target
on the "right" road (but "wrong" arc) and adds a u-turn to get on the road
arc that was selected as target.

Well - I used
--x-cycle-map

but for some intersections it would still not work. In 4 out of 10 long distance routing examples I tried in Basecamp - the result was better. In 4 it was the same, and in 2 it was slightly worse.

So overall it is a modest improvement - but I would have hoped for a bit more. Still - clearly and improvement.

Sorry - I was on an enduro MTB Race for the last week - I will start testing on Tuesday...

Hi all,

attached is v2 of the patch, the binary is here:

Correction: the previous versions did not change angles like this: /\
Improvement: For bicycle maps, the angle is changed up to 90° for arcs
with high road speeds.

Options (--x-fix-sharp-angles and --x-cycle-map) are the same.

@Felix: I wait for your feedback now, as I have no way to test with your style.

Gerd
