  • NCSA Research Note: Validation of the National Estimates Produced From NASS GES (DOT HS 812 099), The National Automotive Sampling System (NASS) General Estimates System, operated by the National Highway Traffic Safety Administration, is responsible for produc¬ing national estimates for all types of motor vehicle traffic crashes that occur throughout the United States each year. The objective of this research note is to validate the GES estimate on the total number of motor vehicle traffic crashes occurring annually. The method used was to compare an annual GES estimate with numbers of motor vehicle traf¬fic crashes reported by the 50 States and the District of Columbia in the same year.

NCSA, an office of the National Highway Traffic Safety Administration, is responsible for providing a wide range of analytical and statistical support to NHTSA and the highway safety community at large.

Data Modernization

NHTSA is conducting a comprehensive review of the National Automotive Sampling System (NASS) research design and data collection methods as part of a major effort to modernize the system. Users of NASS and crash data may comment on the future utility of current data elements, recommend additional data elements and attributes, and describe their anticipated data needs.
