In some situations the voicehint calculation brings up an error for roundabouts. P

Hello,

Yes, I had also some times problem with roundabouts..
But just for understanding:
For the first roundabout in the example I get:

Where is the problem, "take exit-2 is for me Ok"?

from brouter.

@EssBee59

RNLB is a roundabout left instruction, where all roundabouts in the example are right (RNDB).

from brouter.

EssBee59 commented on June 20, 2024

thank for the explanation..
OK, I never had this problem...
Strange is, the behavior seems to depend on the profile: Using my profiles I get RNDB, not RNLB

(to test, you can use profile=racebike-verylowtraffic or &profile=trekking_SB
then set the parameter assign turnInstructionMode = 3 AND assign turnInstructionRoundabouts = true because I deactivated this option)

There are more problems inside roundabout.
To make it visible here an export with timode=4

     $turn$ RNDB2;    11;  1.521596; 42.506310;   186; 22(1)24$
     $turn$ RNDB2;    26;  1.521980; 42.504736;   474; 24(2)26 (168)6$
     $turn$ RNDB1;    47;  1.527428; 42.505226;   363; 26(14)26$
     $turn$ RNLB2;    63;  1.531711; 42.505927;   215; 26(9)26$
     $turn$ RNDB1;    75;  1.534200; 42.506397;   221; 26(-5)26$
     $turn$ RNDB2;    88;  1.536711; 42.506933;   208; 26(-4)26$
     $turn$    TR;   109;  1.537869; 42.508118;   224; 6(87)6 (1)6$

First you see the wrong RNLB command - as discussed before. You can also see the RNDB2 command has two exits but only one angle and its an angle of 1 - nothing very meaningful.
So here is an additonel rework on roundabout problems.

     $turn$ RNDB2;    11;  1.521596; 42.506310;   186; 22(-113)24 (-27)24$
     $turn$ RNDB2;    26;  1.521980; 42.504736;   474; 24(-156)26 (-18)26$
     $turn$ RNDB2;    47;  1.527428; 42.505226;   363; 26(-76)26 (-49)26$
     $turn$ RNDB2;    63;  1.531711; 42.505927;   183; 26(-89)26 (-36)26$
     $turn$ RNDB1;    75;  1.534200; 42.506397;   221; 26(-95)26$
     $turn$ RNDB2;    88;  1.536711; 42.506933;   208; 26(-131)26 (-37)26$
     $turn$    TR;   109;  1.537869; 42.508118;   224; 6(87)6 (1)6$

And a small graphic output for the situation here
