One the oldest tickets:
is all about this. Your observation is correct, there is currently no separation
between durations and "routing weight". We've been discussing implementing
this recently (at Mapbox), but no definite plans yet. It will increase the
If you take your second option, you can consider encoding the extra metadata
you need in the "name" attribute, and split it out again when you receive your
route results. Note that OSRM emits a turn instruction every time the "name" changes,
so you'd need to cater for that if you're displaying turn-by-turn instructions to users.
