Summary: 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. General Estimates System data come from a nationally representative sample of police reported motor vehicle crashes of all types, from minor to fatal. The information is used to estimate how many crashes of different kinds take place, and what happens when they occur. The Crashworthiness Data System has detailed data on a representative, random sample of thousands of minor, serious, and fatal crashes.
