Wrongly car navigation routing over path, badly bicycle routing over grass

SLMapper commented 2 weeks ago

Description

highway=path is clearly not for car navigation, but still is wrongly chosen by Osmand.

highway=track, tracktype=grade5, surface=grass and highway=path, surface=grass is clearly not for bike, but still is wrongly chosen by Osmand, when there ways of better surface around it.

Steps to reproduce

Both appeared in longer route (~30 minute each). Only showing the relevant part here:

car routing from 48.59359° N, 8.87231° E to 48.59435° N, 8.87470° E (routes over https://www.openstreetmap.org/way/551096127)
bike routing from 48.55116° N, 8.94187° E to 48.55221° N, 8.92684° E (routes over https://www.openstreetmap.org/way/938199238)

Actual result

Invalid road is chosen
Road with poor surface was chosen

Expected result

Chosing a valid route
Chosing a route with conditions matching the vehicle (there is a connection via a tracktype=grade1 and tracktype=grade2, which is a bit longer but much more fitting for a bike)

The bug was partially reproduced. Initially, I attempted to reproduce the issue by building navigation for a car, where the navigation is built exactly as specified by the user. Following that, I attempted to build navigation for a bicycle, but the method for bicycle navigation is currently different.

Additionally, car navigation on the Web version is constructed differently compared to the app, despite Live updates.

The bug has been reproduced. In the app, when using the reset car profile, the navigation wrongly routes through bike paths, even with live updates. On the Web version, the navigation works correctly and takes a detour. However, if you enable the "Short way" option on the Web version, it also incorrectly routes through bike paths, just like the app.

Bicycle navigation is now working correctly.

Thank you very much for reproducing the issue with car navigation. I was also able to reproduce the bicycle issue of routing over a highway=path, surface=grass using "short way" on the web version.

Another bike example I experience yesterday even without "Short way enabled" grafik

where OsmAnd unexpectedly

prefers tracks with surface=grass → surface=grass → hw=track without additional information
over continuing on the good tracks that can be seen below surface=gravel, tracktype=grade2 → surface=gravel, tracktype=grade1

Another crazy bike example with "Short way" enabled, where

OsmAnd routes over a foot=designated, highway=footway, lit=no, surface=asphalt, width=0.8
instead of taking the roads appropriate for bikes (this is when disabling "Short way" on the website, but on my phone I had to manually put a way point for OsmAnd to go there, despite that I had "short way" disabled)
