Actual route

Expected route

Turning right and going straight through (works with a via point, works with shortest route, doesn't work in balanced mode, works on OsmAnd website even in balanced mode).

Your Environment

OsmAnd Version: 4.8.6
Android version: 10
Device model: Galaxy S9

Anything else?

Not sure if this is a bug or expected behavior in balanced mode. Looks very suspicious / strange, nobody would choose this route.

The bug was not reproduced. To reproduce , I created navigation using the provided coordinates: start at 51.88060, -9.58480, and finish at 51.87994, -9.58320, with the bicycle profile and tried both Balanced and Shorter riding styles.

The navigation was built correctly without any detours, both in the app and in the web version. I recommend updating your maps and resetting your profile settings by going to Menu → Settings → App profile (Bicycle) → Reset to default.

Here’s the link to the web version for reference: OsmAnd Navigation.

OsmAnd~ 4.9.0#3212m, released: 2024-09-18

I recommend updating your maps and resetting your profile settings by going to Menu → Settings → App profile (Bicycle) → Reset to default.

My map is up to date, the app is the latest stable version and I can reproduce this with a freshly created bicycle profile.

I see only detour for safety - driving_style_safety https://osmand.net/map/navigate/?start=51.880600,-9.584800&end=51.879736,-9.582648&profile=bicycle&params=bicycle,driving_style_safety,driving_style_balance:false#18/51.88047/-9.58329, not for balance

I've tried with and without, the result is the same.

cycleway:both = no https://www.openstreetmap.org/way/24231331

This is a physical property, not a legal one. Does it affect the balanced routing?

The other roads involved also don't have dedicated cycleways.

For safety it's deprioritized secondary vs tertiary

For safety it's deprioritized secondary vs tertiary

That makes sense. But crossing a secondary is probably as dangerous as riding a short stretch along it. Are there penalties for crossing roads that are of higher priority than the current one?

Your report is about - Bicycle, balanced, no live data. So in the end we didn't reproduce it.
