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.

TransitFlow — using Python and Processing to visualize regional transit frequency

Transitflow is an experimental set of tools that generate spatial-temporal transit frequency datasets and visualizations from the command line.

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.

Mapzen Flex expands your travel horizons!

Timed-distance matrix, Isochrone, Optimized route and Elevation services are coming to Mapzen Flex.

OSMLR traffic segments for the entire planet

OSMLR provides a stable linear-referencing system atop the ever-changing network of roadways in OpenStreetMap. We're now releasing a preview build of OSMLR segment tiles for the entire planet.
