A "data-driven" approach to improving map-matching: Part IV — Map-Matching and the Built Environment

The final part of a series on how Mapzen validates, fine tunes, and deploys our map-matching, in support of the Open Traffic platform and other applications.

A "data-driven" approach to improving map-matching, Part III -- Post-processing for Quality

In part three of how Mapzen validates, fine tunes, and deploys our map-matching, we'll describe how we ensure that only the best-quality matches make their way into the Open Traffic datastore.

A "data-driven" approach to improving map-matching, Part II

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.

New and improved bike routing, with low stress options

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

A "data-driven" approach to improving map-matching, Part I

We wanted to take some time to explain exactly how map matching works, and how we use it. This will be the first in a series of three blog posts on how Mapzen validates, fine tunes, and deploys our map-matching services to meet the needs of our users.

Map Matching is ready to Flex

We're excited to release Mapzen Map Matching, the latest addition to the Mapzen Mobility services. Our Map Matching service takes in a trajectory of latitude/longitude coordinates and returns back a route line that is snapped to the OpenStreetMap road network and enriched with attributes, like speed limits and freeway exit signs.
