Q: What is the ACIR?
A: Early Automotive Crash Injury Research (ACIR) study (Reference 1), which was initiated in 1952 and aimed at (1) identification of injury causes and (2) measurement of the effectiveness of countermeasures, relied on relatively gross evaluations of vehicle damage as a basis for the classification of exposure severity. Photographs of the damaged vehicles were compared with reference photographs (see below) to segregate individual cases into four accident categories (front, side, rear and rollover) and five categories of severity (minor, moderate, moderately severe, severe and extremely severe). Travel speeds were based on police estimates.
