The human body cannot withstand direct vehicle impacts above 30 km/h but increased protection, such as being inside a safe vehicle, helps manage crash energy and reduce injury risk in crashes. Regardless of protection, injury likelihood still increases with increasing impact speed, and this is dependent on pre-crash travel speed and speed limit compliance. Therefore, the speed limit set on a road is critical to reducing crash injury risk, and while the Safe System considers speed limits and injury risk in the context of different crash types and a population-level injury tolerance, it often overlooks inequities and other key risk factors such as the age of the injured and time to medical care. This research applies a multi variable occupant injury prediction algorithm to demonstrate how injury risk is stratified and varies with age and emergency transport time, offering an approach to a more equitable Safe System approach. | | Conference Name | 2025 Australasian Road Safety Conference | | Conference Abbreviation | ARSC25 | | Conference Location | Perth, Western Australia | | Conference Date | 20-23 October 2025 |
