[OSRM-talk] MLD for multiple routing graphs?

[Daniel Patterson]

Hi Frederick,

  Keep your eye on this issue:
https://github.com/Project-OSRM/osrm-backend/issues/4007

  We're working on something that could be used like this.  It's mostly
targeted at supporting "avoid X" behaviour, but eventually, it will
probably support the use-case you're describing.

  There are a few complications (like different instruction types issued by
different modes) that walk+bike+car would create, but the ticket above is
the first steps in the direction you're thinking of.
