In part two of how Mapzen validates, fine tunes, and deploys our map-matching, we'll dive a bit deeper into the internals of the algorithm itself to see how we can use our validation metrics to fine-tune the map-matching parameters.

This summer, we have enhanced bicycle costing. Not only is overall routing improved, but `use_roads'` and `use_hills` are now much more versatile.
