The MUARC-TAC enhanced crash investigation study: study update, analysis of crash types and contributing factors [Abstract]

This paper presents an update of the Monash University Accident Research Centre (MUARC) – Transport Accident Commission (TAC) Enhanced Crash Investigation Study (ECIS) as well as an exploration of the characteristics of injured drivers, crash types and factors implicated in crash occurrence. Three configurations are of particularly high frequency and severity, whilst crashes involving young and older drivers are different in nature and have different contributing factors. Fatigue, driver error, and pre-crash driver blackouts due to medical conditions were prominent contributing factors. Injury severity would be significantly lower in 32% of cases if either front or side airbags were fitted. The findings point to key risk factors that can be addressed in road safety strategies.
