Osmand still shows wrong lane count. This is the real turn lane configuration. Nowhere are 5 lanes per direction. Just before the segment where now it shows correct lane nr. it shows 5 lanes, but there are only 4.

And Уральская street from 3rd video at the end has turn:lanes:backward=reverse;left|through;left|right. Way 868135783. So lanes need to be like this.

[vshcherb]

To do: No 1 (left|through|through|right and instead we see only C|C|C|C|C), No 2 - should be fixed. No 3 - not reproduced.

[razor74]

Hi. the problem is present on map release from may. The map show now 6 lanes instead of 3.

PR https://github.com/osmandapp/OsmAnd/pull/17421 Test case 53.884649, 27.619833, before/after. OsmAnd do not show left turn and reverse at same time (in UI), but code instruction is consist reverse (TU) 34233649 Go ahead (+TL,TU|+TL,C|TR):

Test case 44.386406, 26.139163 after PR https://github.com/osmandapp/OsmAnd/pull/17421 Before/after Lanes configuration of intersection are right, but this way to fuel station also counting as possible lane. I suggest to avoid all service=* roads (but not all highway=service) in lane counting. (Is wrong, see place 35.83824, -78.64158) Will be in separate pull request.

After data fix:

Test case 50.24268, 18.9957 Need to fix data. Way 234238770 (through|through|through;right) is not connected with way 128275340, therefore OsmAnd generate syntetic lanes instruction.

Before/after fix data:

JOSM:

Test case 49.57615, 11.0159 (test "21.Äußere Nürnberger Straße C" with new data is ignore=true in PR) Need to fix data or create virtual syntetic lanes for way 430007222 like TL|C or TL|TL|C|C (from way 515591061). Ways with lanes: Way 30405356 left|left|through|through|right|right that use for instruction. Way 515591061 left|left|through|through

Summary Jun 16 2023

All mentioned cases are fixed except 3

• [x] 1. Topic starter https://github.com/osmandapp/OsmAnd/issues/16752#issuecomment-1592594307 - investigating how to fix
• [x] 2. Data need to be fixed https://github.com/osmandapp/OsmAnd/issues/16752#issuecomment-1592644516 - however we're checking why main lane is turn slight left and not straight
• [x] 3. Data need to be fixed https://github.com/osmandapp/OsmAnd/issues/16752#issuecomment-1592678308 - however we can fix it somehow different (please create new issue)
• [x] 4. Migrate to C++
• [x] 5. Fix PR comments

[vshcherb]

Slightly different fix for a topic starter that we've udpated the map https://www.openstreetmap.org/changeset/137612121 cause service roads could be counted in turn:lanes - https://www.openstreetmap.org/way/693970262
