Traffic Fatalities and Injuries in the New York Metropolitan Area
In 2007:
– Over 1,000 fatalities in New York metro area
• 273 in New York City proper
– 200,000 injuries in New York metro area
– Comparison:
• 41,000 fatalities nationwide
• 2.5 million injuries nationwide
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
$1 to $5 billion
Cost of Crashes in the New York Metropolitan Area
$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)

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

Comparison To Other Cities (2005 data)
Examples Congestion Crashes Rochester: $64 million $1.0 billion Albany: $86 million $825 million Buffalo: $112 million $1.1 billion Hartford: $166 million $1.3 billion Bridgeport: $280 million $955 million New Haven: $104 million $1.1 billion

Ratio of Costs (2005 data)
Ratio Crash Cost/Congestion Cost NYC: 2.44 Albany: 9.46 Buffalo: 9.74 Rochester: 15.85
Conclusions
The cost of crashes is 2.5 times more than the cost of congestion (2005 data)
Congestion: $67.6 billion
Crashes: $166.7 billion
You can develop your own Cost of Crashes analysis for any geographical area and educate the public
Speed not only kills – it also costs…
