Public Traffic Camera Registry & Live Feed Health - US & Global DOT / Transit Networks

A normalized, analysis-ready registry of publicly operated roadway and transit cameras drawn from 25 government networks across the United States, Canada, the United Kingdom, and Finland - state DOTs, municipal traffic agencies, and 511 systems. Each source carries a stable identifier, geolocation (lat/lng), operating agency/provider, source type, advertised capabilities, and a derived programmability tier. The feed is paired with near-real-time **feed health** (live / degraded / dead, with confidence and reason codes) and an **analysis-readiness** layer (calibration / homography status, rule-readiness, action-proof readiness). Roughly 9,800 cameras, refreshed continuously via change-data-capture. Use it to build live coverage maps, monitor public-camera uptime across agencies, plan sensor or autonomous-vehicle routes, validate geospatial data quality, or seed traffic and mobility models. Free tier. Derived metadata only - no raw video or imagery is included or redistributed.
