Research in this period centered on quantifying risk and injury severity in traffic crashes, with strong emphasis on linking impairment markers such as blood alcohol concentration to crash outcomes and injury severity. Standardization across studies emerged as a key goal, led by the Injury Severity Score, enabling cross-study comparability, trauma registries, and unified triage approaches. Forensic radiology and systematic imaging documentation also gained momentum, shaping understanding of fatal crashes and informing injury classification.
