Instructions

As with Ohio/Statistics#Instructions, download the latest .osm.pbf extracts of Ohio, Kentucky, and Indiana from Geofabrik. Then merge them and extract the Cincinnati metropolitan area:

osmium merge data/ohio-latest.osm.pbf data/kentucky-latest.osm.pbf data/indiana-latest.osm.pbf -o data/oki.osm.pbf
curl https://gist.github.com/1ec5/4405a6989ab8a3cac839278b3f6e457a/raw/26c3c168280e9c9b3bedc62d2c3fb5aff7c05945/cincinnati.geojson
osmium extract -p data/cincinnati.geojson data/oki.osm.pbf -o data/cincinnati.osm.pbf

Then install Vainilla and follow the instructions in the tool's readme to generate the pathway statistics.

Notes and references

  1. A one-way road tagged highway=motorway/trunk/primary/secondary/tertiary may or may not be one side of a divided road. The lower bound assumes they all are, causing false positives' lengths to be undercounted by half. The upper bound assumes none of them are, double-counting the length of every false negative.
  2. FHWA calls this category “Other freeways and expressways”, but as seen in TIMS, ODOT classifies expressways and super-twos as principal arterials.
  3. Excluding all highway=service roads and roads with access=* values other than access=yes, access=destination, or access=designated.
  4. Only marked or signposted turn lanes; excludes implicit turns.
  5. 5.0 5.1 Maximum speed limits, including advisory speed limits.
