PSI | Session 2 | 3-4 Mar 2011 |
Mr Petit provided an update on the progress on the development of the ISO/WG6 WorldSID 50th injury risk curves (PSI-02-15). Mr Petit advised that the ISO/WG6 had agreed to use the survival analysis statistical method to construct the injury risk curves. To enable injury criteria limits to be finalised the ISO/WG6 will now need to establish the most suitable injury risk predictors for each body region (e.g. pelvis injury risk could be predicted by 3ms pelvis acceleration and/or pubic force) and the recommended thresholds. The same process would need to be followed for the WorldSID 5th. WG6 would meet again in May. Mr Belcher presented data (2000-2009) on fatalities and serious injuries in Victorian (Australian state) side impact crashes by occupant age (PSI-02-16). It was noted that the 45 year age, which is currently used for the age scaling of current side impact dummy injury risk curves, exceeds (by age) around 85% of Victorian pole/tree side impact crash fatalities, but only around 50% of other side impact fatalities. Mr Ridella presented a summary of an UMTRI investigation of the effects of occupant age on AIS 3+ injury outcomes (PSI-02-17). Mr Ridella undertook to investigate with UMTRI the possibility of separating pole side impacts from other side impacts in the data presented in this study. In response to a question from Ms Tylko, Mr Ridella indicated that while it would decrease the number of available cases, it was possible to identify contact point in the NASS data base. |
