What is NASS?

Split from prior combined 'What is' about PDOF and NASS (now topic is What is PDOF?)

What is NASS?
  • Collecting Relevant Data and Information
    • The National Automotive Sampling System (NASS) provides NHTSA an efficient and reusable resource with which to conduct data collection representing a broad spectrum of American society. Using a core set of crash data components, NASS has proven a reliable resource for a variety of agency sponsored electronic data collection efforts over the past 10 years.

      NASS is composed of two systems - the Crashworthiness Data System (CDS) and the General Estimates System (GES). These are based on cases selected from a sample of police crash reports. CDS data focus on passenger vehicle crashes, and are used to investigate injury mechanisms to identify potential improvements in vehicle design. GES data focus on the bigger overall crash picture, and are used for problem size assessments and tracking trends.
The SMAC computer program and then CRASH computer program were invented and developed by Raymond R McHenry/ Calspan as part of research related to NASS investigations for the improvement of safety on our nation's highways
