In-depth crash investigations in South Australia

EXTENDED ABSTRACT: The purpose of in-depth crash investigation is to produce holistic, high quality information on crashes that is not available from any other source, in order to understand the factors that contribute to crashes occurring, and to provide data necessary for countermeasure evaluation. This paper gives an overview of the method used for the Centre for Automotive Safety Research’s (CASR) in-depth crash investigations and demonstrates the value of such data collection through examples of the research that it has enabled on a variety of topics, including: travel speed, alcohol, pedestrians, roadside safety, young drivers, and new vehicle technology.
