Bizarre Routing

[P Wat]

Has bizarre routing recently increased or is it only affecting me more than it used to?

I've recently been experiencing numerous different instances.

See attached picture for an example.

Location is

51°30'52.9"N 1°00'43.0"W

51.514694, -1.011944

Anyone know the cause and/or solution?

Thanks

Hi! I had a look at OSM (as I'm sure you have) and didn't spot errors or changes in the last couple of months that would explain this (I could have missed something).

I tried to replicate your problem using car routing like this:

 but it didn't happen. (Android OsmAnd+ 3.7.2, England map 1 May 2020.) I also tried cycling, with and without elevation.

But my own observation of poor routing recently has been for walking when a bridleway should be used but isn't. I thought I'd try it at this location, and sure enough:

The bridleway (in green, this is Touring View) should have been used but wasn't, with or without elevation.

Then I thought I'd place an intermediate destination part way down the bridleway, and the turn-by-turn directions go haywire!

I have no idea what's going on! I hope somehow this helps...

Hi A Thompson - Thanks for your input (and sorry for my slow response).
It does seem there is a link between the existence of an intermediate destination, and the bizarre routing.
Fortunately in this instance I know the area, but it could be more of a nuisance in an "unknown" area.
I'll continue to monitor and experiment to see what might be the cause.
