2. 1. Health Losses in Motorcycle Crashes - Injury Analysis of Crashes into Road Barriers and Evaluation of Antilock Braking Systems

   Author : Matteo Rizzi; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Antilock Braking Systems; Powered Two Wheelers; Safety; Injury; Stability; Road Barrier; Health Loss; Crash; Motorcycle;

   Abstract : Motorcycles crashes are a growing road safety problem. While the traditional safety approach has focused on protective gear and rider education, with the Vision Zero approach, the designers of the road transport system are considered responsible for its design and operation.

4. 2. Injury Biomechanics in Car-Pedestrian Collisions: Development, Validation and Application of Human-Body Mathematical Models

   Author : Jikuang Yang; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; impact biomechanics; car; mathematical dynamic model; pedestrian; safety countermeasure;

   Abstract : The aim of this study was to develop and validate human-body mathematical models which can be used to simulate the dynamic responses of pedestrians in a car impact. The main focus has been on simulations of bumper impact to the lower extremities, since lower extremity injuries most frequently occur in car-pedestrian accidents and result in long-term consequences and high social costs.

5. 3. Mathematical Simulation of Vehicle-Pedestrian Collisions: Influence of Vehicle Impact Speed and Front-End Structure on the Dynamic Responses of Child and Adult Pedestrians

   Author : Xuejun Liu; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; child pedestrian; impact biomechanics; mathematical model; vehicle front-end structure; safety countermeasure; impact speed; parametric study; scaling method;

   Abstract : The development of effective countermeasures for pedestrian protection requires an understanding of how the impact speed and front-end design of the vehicle influence the injury risks of pedestrians. Because of the high involvement of children in pedestrian accidents, there is also a need for child pedestrian mathematical models. READ MORE

6. 4. Safety for Children in Cars – Focus on Three Point Seatbelts in Emergency Events

   Author : Isabelle Stockman; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steering; Crash test dummies; Run-off road; Child restraint systems; Child safety; Emergency events; Braking; Pre-pretensioners;

   Abstract : Child safety in vehicles has improved over time. One of the main factors is due to the increased restraint use by children. Nevertheless, studies show that although children are restrained, injuries still occur indicating that restraint systems have the potential for further improvement. READ MORE

7. 5. Characteristics of nearside car crashes : an integrated approach to side impact safety

   Author : Cecilia Sunnevång; Maria Krafft; Mats Lindkvist; Christer Hydén; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; side impact; WorldSID; thorax; injuries; side airbag; sidokollision; WorldSID; thorax; injuries; side airbag; biomechanics; biomekanik; Epidemiology; epidemiologi;

   Abstract : Introduction: Approximately 1.25 million people globally are killed in traffic accidents yearly. To achieve the UN Global Goal of a 50% reduction of fatal and serious injuries in 2020 a safer infrastructure, as well as new safety technologies, will be needed. Side crashes represent 20% of all serious and 25 % of fatal injuries. READ MORE
