Abstract
A comparative analysis of detailed road crash data from four different environments is presented. Three of the studies were on-scene investigations of crashes from Adelaine, Australia: Birmingham, and Worcestershire, England. The fourth set of data was taken from ACIR reports by Cornell Aeronautical Lab., Inc. of predominantly rural crashes in the United States. Where necessary the data were reanalyzed so that the variables being discussed were compatible. Comparisons are drawn between speeds at impact, areas of impact, vehicle damage severity, seated position, injury severity, anatomical injury distribution, and causes of injury for the four sets of data.
