Hi @all,
I'm exploring ways to have the matching algorithm work agnostic to
(most) road restrictions and rather 'trust' the trace I pass in.
I receive continuous GPS locations, with moderate to high resolution in
time, from bikes as well as cabs or buses. It just so happens that some
idiots ride their bikes on roads that OSM (and most laws) thinks they
shouldn't, as well as some cars ignoring bus lane restrictions or buses
leave their lanes. In those cases, matching fails one way or another
([No match], or only partial matches).
I have a hard time wrapping my head around if a profile can actually
fullfill restriction and/or even vehicle type (I can easily work with
multiple graphs, though) agnostic matching, which likely implies a
similar agnostic weighting. I imagine a shortest connection/path
matching should do just that, but then I'm at a loss if that is actually
the case and if so, how to generate such a profile.
Your insights would be much appreciated...
André
I think the weighting is the right think to do. Use high weight on way
there is no legal access. It's some kind of soft access restriction. You
can even weight the opposite of a one way restriction.
But you will have to rework all the samples profiles provided in OSRM.
Frédéric.
