Of cause it does.
It's a graph made out of nodes (with latitude and longitude)
and ways as an ordered list of such nodes.

You can apply all geometry-calculations you like.

If you are interested in writing specific metrics or routing-algorithms
without caring about the rest of the infrastructure
I suggest to look at Traveling Salesman. You can write
a new metric or algorithm as a plugin and it will be selectable
in the config-dialog.

(I'm the maintainer but haven't done anything on it in a while.
  It does however work well for maps up to the size of a major city.)
