Hi François, Currently, no - snapping for coordinates is strictly whichever is nearest (with one exception: https://blog.mapbox.com/robust-navigation-with-smart-nearest-neighbor-search-dbc1f6218be8 ).
I can think of two things: 1. Try using the `/match` API. This API snaps to *many* nearest points (usually within 15m), and tries routes between all combinations, and returns the most likely. As long as your coordinates are reasonably close (<2km), it should be almost usable as a replacement for the `/route` API. 2. You can use the `/nearest` API to return more than one possible snap point within range, then pick one, then request `/route` with the snapped coordinates you have chosen. This is only viable if `/nearest` returns enough information for you to decide which snapping point is best. daniel On Fri, May 4, 2018 at 8:37 AM, François Lacombe <fl.infosrese...@gmail.com> wrote: > Hi all, > > I'm wondering if osrm can weight its snapping choices for start location ? > Especially for footwalk mode. > > There are situations where farer ways can lead to shorter routes. > Currently osrm always snap start location to nearest way but doesn't give > me the shortest route according to my knowledge. > > Is there any trick in the profile to make some ways preferable to snap to? > Should I open an issue regarding this? > > All the best > > *François Lacombe* > > fl dot infosreseaux At gmail dot com > www.infos-reseaux.com > @InfosReseaux <http://www.twitter.com/InfosReseaux> > > _______________________________________________ > OSRM-talk mailing list > OSRM-talk@openstreetmap.org > https://lists.openstreetmap.org/listinfo/osrm-talk > >
