NATIONAL ACCIDENT SAMPLING SYSTEM--NASS--REPORT ON TRAFFIC ACCIDENTS AND INJURIES FOR 1979

The National Accident Sampling System (NASS) is described, followed by statistics compiled from the first year of data collection. The tabulations are unbiased national estimates based on a sample of 3418 accidents from the ten existing NASS sites. Basic figures show the number and percent of accidents by first harmful event, vehicles by body type, and injured persons. Percent distributions are given for accidents and injured persons by day of week and time of day, and by road type and speed limit; vehicles by type and first harmful event; passenger cars in towaway accidents and injury rate for occupants with Abbreviated Injury Scale of 2 or over by magnitude of compartment intrusion; and vehicle drivers and occupants by age, accident type, injury severity, and seat belt usage. Injury consequence statistics show length of hospitalization and time lost from work. Comments are made on the potential of NASS, and appendices cover NASS data elements and statistical design. A national estimate of 48,819 fatalities is extrapolated from the NASS data. The number of fatalities counted in the Fatal Accident Reporting System for 1979 is 51,083 (5% difference).
