[OSRM-talk] Extra backward track?

[Dennis Luxen]

Hi,

> On the other hand, if you move the via point up the right road, it doesn't make the detour: http://map.project-osrm.org/?loc=-30.177584,135.648081&loc=-29.915912,135.154241&loc=-29.013368,134.753616

Yes, that sums it up pretty much.

> I think it would be better if OSRM allowed u-turns in cases like this. Ie. allow u-turns, but with a penalty so they will only be used when no better option exists. Nobody would take a detour of 26 km to avoid a u-turn on road in the countryside.

Right. What we will do is check a couple of nearby road segments and see which one the most reasonable to start/end.
