In conventional traffic safety evaluations, the outcome measure is typically the frequency of police-reported crashes, often with separate estimates for different severity levels. However, some treatments may decrease some crash types but increase others. If these crash types are characterized by different average injury severities, then comparing crash frequencies will not provide the user with an accurate picture of treatment effectiveness. Such a scenario led to the development of the crash cost estimates by crash geometry described in this report.
This paper presents estimates for the economic (human capital) and comprehensive costs per crash for six KABCO groupings (used by police to classify injury) within 22 selected crash types and within two speed limit categories (<=72 kilometers per hour (km/h) (<=45 miles per hour (mi/h)) and >=80 km/h (>= 80 / 50 mi/h)). The comprehensive costs include nonmonetary losses. To produce these cost estimates, previously developed costs per victim keyed on the Abbreviated Injury Scale (AIS) injury severity scale were merged into U.S. traffic crash data files that scored injuries in both AIS and KABCO scales to produce per crash estimates. The detailed estimates of this study make it possible to include crash severity comparisons in the analysis of different types of crashes by attaching costs to them, and to do so in 2001 dollars.
