Locus navigation roundabout errors

It seems Locus has problem with proper counting of roundabout exits (LoRouter online/offline). Unlike all other navigation apps whenever it should show 2nd exit, it always calls it 1st exit. Is it a know problem?

Hello,

please, can you send me the coordinates where the problem occurs?

Everything works fine for me, so I need to try to simulate your exact route.

Thank you.

Now, that is werd!

OK, here it goes, coordinates are as shown by Locus web planner.

Starting point: N52.23002 E20.98424


First roundabout: N52.23002 E20.98424 (Locus should say "2nd exit but it says "1st exit")

Second roundabout: N52.23280 E20.99804 (Locus should say "2nd exit but it says "1st exit")

Third roundabout: N52.23728 E21.02003 (Locus should say "1st exit" and it does so correctly)

Fourth roundabout: N52.23658 E21.02045 (Locus should say "1st exit" and it does so correctly)


Trip back (now I use the same roundabout descriptions as above but in reverse order):


Fourth roundabout: N52.23658 E21.02045 (Locus should say "2nd exit but it says "1st exit")

Third roundabout: N52.23728 E21.02003 (Locus should say "2nd exit" and it does so correctly)

Second roundabout: N52.23280 E20.99804 (Locus should say "2nd exit but it says "1st exit")

First roundabout: N52.23002 E20.98424 (Locus should say "2nd exit but it says "1st exit")

Attached is a GPX file with above track, as generated by Locus web planner.

This is probably caused by non-optimal osm roundabout mapping.


https://wiki.openstreetmap.org/wiki/Tag:junction%3Droundabout

"Connecting ways. Connect the approaching roads/ways with the roundabout. Do not directly connect approaching with departing roads. A segment of the roundabout is required between these roads.

This way, routers can safely recognize that a section of the roundabout has to be driven through"

Complex subject anyway.
