Abstract

Objective: In Europe, Powered Two-Wheelers (PTW) riders are involved in 15% of all traffic fatalities and the most serious injuries are sustained on the trunk and the head. The aim of this work is to study motorcyclist impact conditions through the reconstruction of 8 real accidents leading to AIS3+ trunk injuries.

Methods: Based on multi-body simulations, key parameters such as impact speed, body impact angles and impacted obstacles are deeply analyzed to determine their influence on injury severity.

Results: Oblique and lateral impacts tend to increase the risk of rib fractures. Trunk impacts against vehicles show predominant normal speed components (25-40 km/h), while impacts with the ground have higher tangential speeds (40-50 km/h). Two main impact configurations for the trunk are proposed to reproduce impact conditions during PTW accidents causing AIS3+ trunk injuries.

Conclusion: This study allows a better understanding of trunk injury mechanisms in PTW accidents and can be used to improve protective device design.

期刊介绍： The purpose of Traffic Injury Prevention is to bridge the disciplines of medicine, engineering, public health and traffic safety in order to foster the science of traffic injury prevention. The archival journal focuses on research, interventions and evaluations within the areas of traffic safety, crash causation, injury prevention and treatment. General topics within the journal''s scope are driver behavior, road infrastructure, emerging crash avoidance technologies, crash and injury epidemiology, alcohol and drugs, impact injury biomechanics, vehicle crashworthiness, occupant restraints, pedestrian safety, evaluation of interventions, economic consequences and emergency and clinical care with specific application to traffic injury prevention. The journal includes full length papers, review articles, case studies, brief technical notes and commentaries.
