Samenvatting
A design is presented for a national accident investigation program based on sampling theory. The system described has 3 major facets (1) a program for continuous acquisition of data of a random sample of all towaway pedestrian-bicycle-motorcycle accidents occurring in the U.S.; (2) a program for occasional acquisition of additional data on selected topics quickly and on-call, and (3) a program for conducting in-depth or multidisciplinary accident investigations for accidents of particular interest.
