Performing Organisation Accident Research Centre Building 70 Monash University, 3800, Victoria Australia Sub-Task Participants Pilot: Monash University Accident Research Centre Sub-contractors: Monash University Accident Research Centre BASt Advisors: LAB Observers: NASVA GDV JARI UK Department for Transport Ford Abstract In previous SARAC work comparing the relationship between injury outcomes in real crashes and the results of EuroNCAP testing, injury outcomes in real crashes have been assessed at the broadest level with the real crash outcome measure being an average overall risk of death or serious injury to the vehicle driver across all body regions. Being able to make comparisons between injury outcomes on a finer injury severity scale and by body region with results from EuroNCAP testing by body region on the crash test dummy would allow much finer assessment of the ability of EuroNCAP to reflect real world outcomes in crashes. The aim of this sub task was to assess the suitability of available European in-depth crash data sources for comparing real world crash outcomes by body region and on a finer injury severity scale with results of EuroNCAP testing by body region. This study examines the suitability of two existing European databases for in-depth analysis and summarises the data requirements for future analysis.

Being able to make comparisons between injury outcomes on a finer injury severity scale and by body region with results from EuroNCAP testing by body region on the crash test dummy would allow much finer assessment of the ability of EuroNCAP to reflect real world outcomes in crashes. The aim of this sub task was to assess the suitability of available European in-depth crash data sources for comparing real world crash outcomes by body region and on a finer injury severity scale with results of EuroNCAP testing by body region. Earlier Australian analysis shows the potential for comparing injury severity outcomes in real crashes and NCAP testing score components by body region and using the finer AIS injury severity scoring system. It was able to identify significant correlations between score components and real crash outcomes in specific body regions in each of the test configurations considered. The analysis was limited, however, in that it did not include adjustment for differences in driver characteristics and crash circumstances between vehicle models that may have confounded the results presented. Ideally, analysis should have included adjustment of such differences. However, the limited data available for analysis meant the adjusted analysis was not feasible. Two European in-depth crash inspection data sources were made available for assessing the general suitability of such data sources for examining the relationship between real crash outcomes and EuroNCAP test results by body region of injury. Suitability of both the CCIS and PENDANT databases for assessing the relationship between EuroNCAP tests and real crash outcomes by body region and more specific injury severity outcome are related to the content and coverage of the data. Both databases appear in theory to be suitable for comparing to EuroNCAP results by body region and more specific levels of injury severity. Both have the information on injury severity by body region and sufficient details on vehicle model and year of manufacture to match with EuroNCAP test data. They also both appear to contain the
