  2. 1. Increased bicycle helmet use in Sweden : needs and possibilities

    Author : Sixten Nolén; Kent Lindqvist; Staffan Janson; Linköpings universitet; []
    Keywords : Bicycle helmet us; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Abstract : Background: From the perspective of what is called "vision zero" in Sweden, fatalities and injuries among bicyclists are unacceptable. Despite that, bicyclists constitutes approximately one third of all road user inpatients in Swedish hospitals, which is about the same proportion seen for drivers and passengers of motor vehicles.

  4. 2. Prevention and prediction of head and neck injury in traffic accidents - using experimental and numerical methods

    Author : Peter Halldin; KTH; []
    Keywords : Head injuries; neck injuries; prevention; roll-over; motorcycle; helmet;

    Abstract : Injuries to the head and neck system are potentially amongthe most serious injuries in humans, since they may damage thespinal cord. It is therefore important to develop safetysystems that can prevent injuries to the neuro- system, therebyreducing human suffering and costs to society. READ MORE

  5. 3. Searching for causal effects of road traffic safety interventions : applications of the interrupted time series design

    Author : Carl Bonander; Ragnar Andersson; Finn Nilson; Claes Tingvall; Karlstads universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Causal inference; Repeated measures; Methodology; Econometrics; Injury Epidemiology; Vulnerable Road Users; Time series analysis; Risk- och Miljöstudier; Risk and Environmental Studies;

    Abstract : Traffic-related injuries represent a global public health problem, and contribute largely to mortality and years lived with disability worldwide. Over the course of the last decades, improvements to road traffic safety and injury surveillance systems have resulted in a shift in focus from the prevention of motor vehicle accidents to the control of injury events involving vulnerable road users (VRUs), such as cyclists and moped riders.

  6. 4. Towards improved motorcycle helmet test methods for head impact protection : Using experimental and numerical methods

    Author : Shiyang Meng; Svein Kleiven; Peter Halldin; Mazdak Ghajari; KTH; []
    Keywords : Head Injuries; Helmet; Injury Prevention; Motorcycle; Test Standard; Finite Element Method; Applied Medical Technology; Tillämpad medicinsk teknik;

    Abstract : Head injury is the leading cause of death and major trauma for users of powered two-wheelers (PTWs). Helmet use can prevent and reduce head injuries when a crash is inevitable. However, today’s motorcycle helmets do not protect equally against all types of head injuries. READ MORE

  7. 5. Subband Beamforming for Speech Enhancement within a Motorcycle helmet

    Author : Per Cornelius; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Beamfroming; Microphone array system;

    Abstract : The increased mobility in society has led to a need for convenient mobile communication in many different type of environments. Environments such as a motorcycle helmet, engine rooms and most industrial sites share a common challenge in that they often offer significant acoustic background noise. READ MORE
