Which highways & railtracks datasets should journalists cite first?
We rank for citability, not brand familiarity: relevance to this persona first, then Datadory's 10-point quality score inside each band. The wider inventory sits in our highways-railtracks data hub.
Where do official US highway statistics come from?
FHWA Highway Statistics Series (1945-present) is the top-scored record here at quality 10: eighty years of state-level tables, legacy XLS, PDF, zipped bridge tables and ASCII inventories, with CSV available through datahub.transportation.gov mirrors.
Highway Performance Monitoring System (HPMS) carries FHWA's official route-level inventory, built from state submissions since 1978 and distributed as per-state shapefiles plus ArcGIS FeatureServer REST queries returning JSON and GeoJSON. National Bridge Inventory (NBI) ASCII Files publishes an annual structure-level census with a published format dictionary - fixed-width ASCII, CSV, ZIP and PDF - which is what makes an investigation reproducible: any reader can re-download the same file and re-derive your table.
What can you map without paying for geometry?
Geometry for published maps comes from the OpenStreetMap family, and licensing decides how you may reuse it.
OpenStreetMap Overpass API teaches and verifies claims through transparent, citable query syntax: the query itself is publishable evidence of what you extracted, returned as JSON, GeoJSON, XML, PBF or CSV. Overture Maps Transportation Theme sits beside it for scholarship, citing versioned monthly releases with changelogs in GeoJSON, Parquet and GeoParquet.
Two lower-maintenance layers finish the toolkit. Natural Earth Roads and Railroads relies on versioned public-domain snapshots through 5.0.0 - static shapefiles, no update risk, ideal for reproducible teaching maps. OpenRailwayMap renders commercial delivery terms-credited rail styles daily as PNG tiles with a JSON facility-search API; it holds relevance 2 rather than 3, so treat it as illustration, not as the evidentiary base.
How fresh is this data, and what should a citation include?
Against the catalog, where 22.6% of datasets.8% at least weekly, this slice is fresher than typical precisely because mapping platforms dominate it.
Annual inventories deserve a lag caveat - a condition rating describes the last inspection cycle, not today's bridge.
