Accident & Exposure Risk
Likelihood of crashes and exposure pressure driven by crash frequency, severity, and traffic density. This page explains the public signals behind accident & exposure risk and how they tend to show up in claims and pricing pressure in Utah County.
County signal
55
/ 100
Crash frequency is above the national distribution. Fatality severity is below the national distribution. Traffic exposure is near the national midpoint.

Core signals
Primary public inputs that define accident exposure in Utah County.
Accident frequency
Crashes per 100k residents with urban vs rural weighting and trend direction.
Sources: NHTSA (FARS), State DOT crash datasets
Accident severity
Fatal and serious injury weighting to capture loss severity pressure.
Sources: NHTSA fatal & injury stats, State injury severity data
Traffic density & congestion
Vehicle miles traveled per capita with congestion multipliers in metros.

Additional signals
Supplemental exposure signals added as coverage expands.
Intersection risk density
Share of crashes occurring in top 5% of high-risk intersections.
Sources: Local DOT crash maps, Open crash GIS datasets
Why accident exposure matters
Accident exposure captures how often crashes occur, how severe they are, and how much time drivers spend on the road.
- More crashes mean more claims, which can lift pricing pressure over time.
- Severe crashes push claim costs higher even if frequency is stable.
- Congestion and long commutes increase exposure, especially at peak hours.
