NAPSPAN provides the traffic infrastructure data that fleet managers, navigation developers, logistics platforms, and risk analysts actually need — and can't get anywhere else.
Send an origin, a destination, and your truck's profile to one endpoint. NAPSPAN builds a truck-aware route, then hands back the hazards on the corridor — bridge clearances and posted limits where each NAP publishes them, ADR tunnel-category routing for hazardous loads, live RTTI/SRTI incidents, and weather — each one severity-ranked with a projected arrival time. You see the conflicts before dispatch, not after a driver is already on the road.
One POST /routing/route call returns the route geometry plus a ranked warnings[] list: clearances, restrictions, incidents, weather.
Pass your hazardous-goods class and tunnel category — the route stays out of tunnels your cargo is barred from under the ADR tunnel-restriction codes.
Height, width, length and weight limits as each Member State publishes them, flagged per violated dimension along the corridor.
Auto-saved for re-checking against live conditions at no quota cost; persist a route to keep it and get webhook alerts as hazards change.
HERE and TomTom sell traffic flow. NAPSPAN gives you the infrastructure data they don't — 10,000+ camera feeds, DMS sign messages, road surface conditions, and weather station readings. GeoJSON-native, ready for Leaflet or Mapbox.
Direct image and stream URLs from 40+ states. Refresh every 1–5 minutes.
Real-time text displayed on highway dynamic message signs across 30+ jurisdictions.
Surface state (dry, wet, icy, snow-covered) and chain requirements from 15+ states.
Every endpoint has a /geojson variant. Drop responses directly into your map layer.
Check corridor reliability, active closures, and seasonal restrictions before dispatching. NAPSPAN tracks event lifecycles — when an incident started, how it escalated, and when it cleared — so you can build smarter ETAs.
Incidents, construction, closures, and weather events across 57 jurisdictions with severity levels.
Full event history — severity changes, lane updates, ETAs — for clearance time prediction.
Top corridors by incident frequency, clearance time P50/P95, and reliability scoring.
Weekly state-level diesel prices (EIA), rest stops with amenity data, and truck parking availability.
NAPSPAN's analytics endpoints give you the data to build risk models. Incident frequency by corridor, clearance times by severity, weather conditions at the time of each event, and geographic clustering — all via API.
Nearest weather station conditions captured at event creation time. Aggregate stats by precipitation and road surface.
Geographic clustering of incidents by configurable grid size. See where events concentrate.
Event time-series by hour, day, or week — grouped by type, severity, or jurisdiction.
P50 and P95 clearance times by event type, jurisdiction, and severity for SLA modeling.
Municipal and regional agencies need to see traffic conditions beyond their own borders. NAPSPAN normalizes data across jurisdictions so you can monitor a metro area that spans multiple states or provinces without integrating each one separately.
Monitor events across state and provincial borders with consistent data format and severity levels.
Query by geographic area, not jurisdiction — get everything within your region of interest.
Bridge conditions, weather stations, road conditions, and EV charging for infrastructure planning.
Track fetch success rates and data freshness per source for data quality assurance.
