Change lanes indication so it's visible lanes split on single lane road

[mdykierek]

Description

I have 3 situations with surprising guidance hints.

1. An intersection (https://www.openstreetmap.org/#map=19/50.26335/18.90335) with a single lane, one way going straight south where hints show and tell - keep left.
   
2. An intersection with two way road with single lane in each direction where hints tell to take left lane (https://www.openstreetmap.org/#map=19/50.25410/18.89678)
   
3. An intersection with two way road with single lane in each direction where hints tell to keep right -well, this at least doesn't cause confusion (https://www.openstreetmap.org/#map=19/50.26335/18.90335)
   

Tried to edit the intersections in osm.org but without success.

How to reproduce?

Your Environment

OsmAnd Version: 4.1.11
Android/iOS version: Android 11
Device model: Mi 9T Pro

Maps used (online or offline):
If you have an issue related to offline maps, tell us the exact name of the map file where the issue occurs and its edition date.

I had a similar problem about two weeks ago. Deleting and redownloading live data fixed it for me. So I suspect this is a bug related to OsmAnd live. Not reproducible so far for me.

Are you using OsmAnd live?

[mdykierek]

I am using OsmAnd live as an active OSM editor.
I have disabled live updates and deleted data - same misbehavior.
Enabled again and downloaded latest updates - same misbehavior.
Since all coordinates are known, you can try on these 3 intersections for yourself with a simulated navigation.

[vshcherb]

it's partially correct behavior prior we have implemented lanes count support. In the end we would like to show that you need to keep left and displayed with 2 lanes though we could generate another Traffic sign with 1 lane and 2 directions i.e. "keep left | keep right".

[mdykierek]

Please note that in case of 2-way single lane each direction case, showing keep left (case no.2 / Wyzwolenia and opposite to case no. 3 Polna) it can be dangerous - left lane is opposite direction. I was surprised as I have not seen guidance like that in my past experience with directions. Will try driving with Sygic and Google more to check.
Isn't it a bit exaggerated? Does it make sense to take left or right side of a single lane?

[scaidermern]

Does it make sense to take left or right side of a single lane?

Definitely not. If there is just a single lane (for the current direction) then there is absolutely no reason to display more than one in the lane guidance.

It should be an icon with road split

Might be related to this issue: #13383

[OpenSourceForEver]

Keep in mind that an icon implies having to look at the device screen, which is dangerous. The voice instructions should be changed so that there are no mistakes if you do not look at the device screen.

We also need to fix this issue #15075

[mdykierek]

This is most annoying in e.g. Finland.All highway parkings cause fake left/right lane guidance and in fact distract and when there is a real manouver to make,one can easily miss.On Aug 15, 2022 14:06, vshcherb ***@***.***> wrote: We also need to fix this issue #15075 —Reply to this email directly, view it on GitHub, or unsubscribe.You are receiving this because you authored the thread.Message ID: ***@***.***>

We would like to have split sign instead of 2 lanes configuration (confusing)

[Prusaker]

When leaving a road (without turn:lanes tag) where there is no braking lane, the program shows an additional non-exist lane:

The road have 3 lanes, however OsmAnd shows 4 lanes.

@Prusaker Have you tried the release version or the latest nightly build?
Cannot reproduce with Nightly and fresh (from February) maps.

[Prusaker]

Yes, in the latest OsmAnd nightly build, lanes are displayed correctly.
Sorry for inconvenience.
