Samenvatting
The NASS CDS provides an automated, comprehensive national traffic crash database. Data collection is accomplished at 24 geographic sites, called Primary Sampling Units (PSUs). These data are weighted to represent all police reported motor vehicle crashes occurring in the USA during the year involving passenger cars, light trucks and vans that were towed due to damage. This manual and the NASS 2011 Crashworthiness Data System's Data Collection, Coding and Editing Manual are the primary documentation supporting the automated 2011 file. (Author/publisher)
