One REST API covering 65 jurisdictions across the US and Canada. Events, cameras, truck routes, bridge clearances — all normalized, all GeoJSON, all real-time.
Stop juggling dozens of incompatible 511 sources. Road511 normalizes 65 jurisdictions plus FHWA, NBI, NREL and WZDx into a single REST contract.
50 US states, 13 Canadian provinces, plus FHWA, NBI, NREL and WZDx — all normalized into one consistent REST schema.
Incidents, construction, closures, weather. Severity levels, lifecycle tracking, line/point geometry. Sub-minute polling on hot feeds.
60+ feature types: cameras, rest areas, weigh stations, EV charging, signs, ferries, border crossings, truck parking, and more.
RFC 7946 compliant. Drop into Leaflet, Mapbox, deck.gl, QGIS — zero transformation, zero glue code.
Filter by radius, bbox, jurisdiction, road, severity. PostGIS spatial indexing for fast, ranked results.
P50/P95 clearance times, corridor reliability scores, time-series volumes. Raw data → operational insights.
HMAC-SHA256 signed payloads. Exponential backoff retries, delivery logs, auto-disable on 5xx streaks.
FHWA STAA-designated truck routes, NHFN freight corridors, NBI bridge clearances and load ratings, plus state-published weight restrictions and truck parking.
Per-adapter circuit breaker (closed/open/half-open) with adaptive backoff. Live status dashboard for every feed.
Two primary resources cover all traffic data: events for time-bounded incidents, features for points of interest. Filter by jurisdiction, type, severity, bbox, or radius.

Road511 tracks every event's full lifecycle and surfaces the metrics fleet ops, engineering, and public-sector teams actually care about.
Time-series volumes by type, severity, and region. Spot seasonal patterns across jurisdictions.
Real-time stream of lifecycle events: created, status changed, severity updated, archived.
Full audit log per event — when it was created, every status change, when it was archived.
Reliability scores for major highway corridors based on incident frequency, duration, severity.
Events for time-bounded incidents. Features for points of interest. Plus national trucking and freight data, all in the same schema.
All 50 US states + DC + HI/AK, and 13 Canadian provinces and territories. 60+ adapter sources, normalized into a single API.
