ACQUISITION OF INFORMATION ON EXPOSURE AND ON NON-FATAL CRASHES. VOL. 2. ACCIDENT DATA INACCURACIES. FINAL REPORT

INFORMATION IS PRESENTED ON INACCURACIES IN EXISTING SOURCES OF HIGHWAY ACCIDENT DATA, ON METHODS FOR CORRECTING THESE INACCURACIES, AND ON METHODS FOR IMPROVING ACCIDENT INJURY DATA BY USE OF HOSPITAL RECORDS. THE MAJOR ERROR IN EXISTING ACCIDENT DATA IS BIAS DUE TO UNDER-REPORTING; THIS IS DUE TO LENIENT CRITERIA AND POLICIES FOR REPORTING OF ACCIDENTS. IT WAS DETERMINED THAT CORRECTIONS IN ACCIDENT- FREQUENCY TOTALS MAY BE ACCOMPLISHED BY EXTRAPOLATIONS OF REPORTING DERIVED FROM SAMPLE COMPARISONS BETWEEN OFFICIAL RECORDS AND DRIVER SURVEYS. ALSO, AVAILABLE NATIONAL SUMMARIES OF HOSPITAL RECORDS COULD BE USED TO IMPROVE ESTIMATES OF THE NUMBER AND SEVERITY OF ACCIDENT INJURIES. /HSL/
