route 'flickering' about osrm-backend HOT 15 CLOSED

the correct (shorter) route is often selected when i release the mouse, but not always.

from osrm-backend.

I have a little more insight into the problem now. For some reason, some roads are falsely identified as one-way streets sometimes. So routing goes only into one direction while the shortest path goes actually in the other. Strange, but interesting.

It's a rounding error from the nearest neighbor lookup that matches a coordinate to a nearest point on any street segment.

Fixed in latest set of changes.

cool, works correctly now for me too!
this was an annoying bug :-)

sorry, but the problem is still occuring, even after commit bd2080f (Flickering of route was caused by rounding error in NNGrid. Fixes ticket #35.)

i've send you a few screenshots.

i believe this issue needs to be reopened

from osrm-backend.

Please try again with latest version from git. It should fix a number of things

from osrm-backend.

I need some more information for this. Could you provide screenshots?

Thanks. I am a bit unorganized right now while heading from one airport to the next.

this is still a problem

from osrm-backend.

it seems like it's related to situations where there's a loop of ways, and you're routing from from one side to the other. seems like there's a single 'opposing' way opposite the the start point, where osrm can't decide which way to go. i think the flickering happens only when the the end point is inside the zone where this 'opposing' way is the closest.
