1. 1. Stochastic finite element simulations of real life frontal crashes : With emphasis on chest injury mechanisms in near-side oblique loading conditions

   Författare :Johan Iraeus; Mats Lindquist; Ulf Björnstig; Mats G Larsson; Joel Stitzel; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; EDR; Real life crashes; Oblique; Finite element; Simulation; HBM; Injury mechanism; Pulse shape; Stochastic; Rib fracture; THUMS; Generic; Statistics; biomechanics; biomekanik; skadeförebyggande; injury prevention;

   Sammanfattning : Introduction. Road traffic injuries are the eighth leading cause of death globally and the leading cause of death among young people aged 15-29. Of individuals killed or injured in road traffic injuries, a large group comprises occupants sustaining a thorax injury in frontal crashes. The elderly are particularly at risk, as they are more fragile. LÄS MER

3. 2. Neck Injury Risk in Rear-End Impacts. Risk Factors and Neck Injury Criterion Evaluation with Madymo Modelling and Real-Life Data

   Författare :Linda Eriksson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; injury criteria; rear-end impacts; neck injuries; mathematical modelling; injury probability; head restraints; BioRID; NICmax; risk factors; WAD; car seats;

   Sammanfattning : Soft-tissue neck injuries, also termed AIS 1 neck injuries, are common after low-speed rear-end impacts. These injuries, which can be long-lasting, have increased in frequency during the past few decades. There is no consensus regarding injury mechanisms; however, injury criteria have been proposed, without yet being fully evaluated. LÄS MER

4. 3. Validity and reliability of vehicle collis : crash pulse recorders for impact severity and injury risk assessment in real-life frontal impacts

   Författare :Anders Kullgren; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :crash recorder; crash pulse recorder; impact severity; injury risk; real-life impacts; measurement accuracy; neck injuries; long-term consequences; reconstruction;

   Sammanfattning : The general objectives of this thesis were to study the importance of valid and reliable data from real- life collisions, especially the effects of inaccurate data on analyses of eg injury risks. Furthermore an objective was to develop and validate an on-board measurement device for acceleration measurements, to be used in reconstructions of primarily frontal impacts. LÄS MER

5. 4. Fatal car crash configurations and injury panorama : with special emphasis on the function of restraint system

   Författare :Mats Lindquist; Ulf Björnstig; Anders Kullgren; Umeå universitet; []
   Nyckelord :Surgery; Deep studies; fatal crashes; small overlap; human FE-modeling; body kinematics; real life safety; Kirurgi; kirurgi; Surgery;

   Sammanfattning : Background: Most traffic safety research projects require accurate real world data which is collected in different databases around the world. This is especially important since the results of these projects form the basis for new crash test procedures and standards. LÄS MER

7. 5. Understanding the system-level for Mobility as a Service : A framework to evaluate full-scale impacts of MaaS

   Författare :Bhavana Vaddadi; Anna Pernestål Brenden; Yusak Susilo; Mia Xiaoyun Zhao; Jeppe Rich; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mobility as a Service; system-level; perspective; framework; experiments; Machine Design; Maskinkonstruktion;

   Sammanfattning : Mobility as a Service (MaaS), as a concept, has been widely popularised and considered to hold promising potential in reducing travel-related environmental impacts and transforming our current transport system. MaaS enables intermodal travel by providing enhanced features for users to access multiple mobility services. LÄS MER
