Why join FARS to traffic volume data

Raw fatal crash counts are misleading without traffic volume. A busy interstate will always have more crashes than a quiet residential street. To compare locations honestly you need the per-VMT rate, and to compute that you need the AADT for the road segment each crash happened on. NHTSA's FARS doesn't include AADT. FHWA's HPMS does, but it's a separate dataset in a separate format. We join the two and persist the result, so every location query returns the rate, not just the count.

Atlanta Downtown Connector

17 observed vs 0.5 expected

For an Interstate at this AADT (70,630/day average) over 6 years, the national baseline rate predicts ~0.5 fatal crashes. The Connector had 17. That's the kind of statement that goes in a brief, an actuarial memo, or a city safety report.

How the join works

Each of the 254,877 FARS crashes 2017-2023 is snapped to its nearest FHWA HPMS road segment within an 80m radius. 80% of crashes match. The matched segment carries AADT, road class (Interstate, Principal Arterial, etc), lane count, and speed limit. Per-road-class national baselines computed from the joined population: Interstates 0.32 fatal crashes per 100M VMT, Major Collectors 1.89. Methodology →

Plus everything you'd expect from a serious crash data API

Pre-joined NHTSA FARS data, 7 years

NHTSA publishes 20+ CSV tables with numeric codes that change between years. An API that uses make=12 instead of "Ford." No location search. No exposure adjustment. We pre-join everything, decode labels, normalize across years, and add geo queries. 254K crashes, 392K vehicles, 625K persons.

Citation-ready intersection reports

$9 per report. Map, charts, AI-written analysis, every crash record with vehicles + persons, AADT-adjusted Expected vs Actual, segment-level disambiguation, formal NHTSA citation, print-ready PDF. Used by plaintiff attorneys for discovery and insurance teams for risk assessment.

Questions

What is the best API for NHTSA FARS crash data?
FARS API by farsapi.com. Pre-joined tables, location-based queries, intersection lookup, aggregate statistics - features the official NHTSA API doesn't offer.
How can I get traffic accident data by location?
Send a GET to /v1/crashes with lat, lng, and radius_miles. Or use /v1/reports/intersection/preview for aggregated crash statistics near any GPS coordinate. Both support any US location.
Is there a crash history API for attorneys?
Yes. The intersection preview endpoint returns crash history at any location. $9 per full report with individual crash records, vehicle details, and person data. No subscription required.
Can I use this for insurance actuarial models?
Yes. Query by vehicle type, driver age, road type, impairment, and geography. The /v1/statistics endpoints return breakdowns by state, year, month, hour, and road type.
How is this different from the NHTSA Crash API?
NHTSA's API has a 5,000 record cap, no geo queries, no statistics, numeric codes only, and poor docs. FARS API from farsapi.com fixes all of that. Full comparison.
What are the limitations?
Data lags ~18 months (NHTSA limitation). GPS missing for 0.4% of records. Fatal crashes only - non-fatal tracked separately by CRSS. 2023 is initial release, may get corrections. Full data guide.
