The major findings of this investigation of involvement rate as a function of speed deviation of the accident-involved vehicle from the mean traffic speed are given in this volume. The primary result is that the likelihood of involvement as a function of speed deviation is a U-shaped relationship. The likelihood of involvement is estimated to be greater by a factor of about 6 to 21, depending on the type of road, for large speed deviations as opposed to small speed deviations and ignoring the accidents involving turning maneuvers. The latter include about 44% of all of the observed accidents. This volume contains a brief statement of the objectives, plan of research, a summary of the results, recommendations and conclusions. In addition the pertinent single page tables and figures from Volume II are included and an example page is given of the long tables.
