FHWA Crash Costs Estimation
Comprehensive crash costs
based on:
– Medically-related costs
– Emergency medical services
– Property damage
– Lost productivity
– Monetized Quality-Adjusted
Life Years (QALYs)
Value of Fatalities and Injuries
Based on FHWA guidance document on comprehensive cost
of crashes
Severity of Crash
2007 dollars
Fatality
$5,800,000
Injury
$72,000

Cost of Crashes in the New York
Metropolitan Area
$1 to $5 billion
$5 to $10 billion
$10 to $15 billion
$15 to $20 billion
Over $20 billion
Cost of Crashes in the New York
Metropolitan Area
$20.2 Billion (2007)
Unreported Crashes
Crash data is as good as the
agencies charged with producing
the data
Property Damage Only (PDO)
crash numbers may not reflect
the actual number of PDO crashes
due to threshold reporting for the
state
