Injury-specific Evaluation of Brain Trauma towards Improved Road Safety

Purpose and goal

** Denna text är maskinöversatt ** Traumatic brain injury (TBI) is a significant threat to road safety. It is a heterogeneous disease that affects different road users with different injury mechanisms. Existing evaluation of safety products follows a "one-size-fits-all" approach with little regard for the complexity of TBI and the diversity of traffic environments. More rational strategies are to establish injury-specific criteria to tailor protection principles to the critical injuries to which their intended users are exposed.

Expected effects and result

** Denna text är maskinöversatt ** This project will combine advanced biomechanical modeling with in-depth accident analysis to improve brain injury assessment tools and develop injury-specific risk functions. Once completed, an advanced computational model of the head equipped with damage-specific criteria will be delivered. New knowledge about the damage types that require priority interventions for different road users will be generated by analyzing damage data from four international traffic databases.

Planned approach and implementation

** Denna text är maskinöversatt ** New pedestrian protection test methods will be developed that better mimic real crash scenarios and brain injury mechanics. The intended users of the project´s results are primarily the automotive industry and the helmet industry, which use these tools and injury risk functions to evaluate the effectiveness of head protection products against various brain injuries and thus inform safety optimization. The protective performance of the headgear will be evaluated against the mechanism-specific criteria developed herein.
