  1. 1. Safety Evaluation of Road Characteristics

    Författare :Sarbaz Najib Othman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Accident data; FOT data; Overtaking maneuvers; Road safety; PC-Crash; Critical road parameters; Horizontal curves;

    Sammanfattning : Accidents are rare and widely distributed on the road network, which poses a challenge for road safety improvement. Traditional methods alone, such as accident analyses and experimental studies, do not explain all accident causation factors. LÄS MER

  3. 2. Safety interventions in Swedish small-scale forestry

    Författare :Björn Edlund; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : In private non-industrial forestry, self-employed work has long been associated with high risks for injuries. This thesis is based on four studies that focused on two of the major high-risk activities in this sector in Sweden: two on felling, de-limbing and bucking trees with a chainsaw; and two on off-road use of quad bikes.

  4. 3. The effect of anti-slip devices on pedestrian safety : method development and practical test

    Författare :Glenn Berggård; Christer Hydén; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic Engineering; Trafikteknik;

    Sammanfattning : Every winter, more than 100,000 pedestrians in the Nordic countries receive medical treatment as a result of falls on slippery surfaces. In addition, the risk of injury reduces interest in outdoor activities during the wintertime. LÄS MER

  5. 4. Vibrational energy harvesting for sensors in vehicles

    Författare :Johan Bjurström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; piezoelectric; anti-resonance; electromagnetic induction; prescribed displacement; low frequency; nonlinear dynamics; small amplitude excitation; automotive safety; vibration energy harvesting; unified modeling;

    Sammanfattning : The miniaturization of semiconductor technology and reduction in power requirements have begun to enable wireless self-sufficient devices, powered by ambient energy. To date the primary application lies in generating and transmitting sensory data. LÄS MER

  7. 5. Safety and mobility of children crossing streets as pedestrians and bicyclists

    Författare :Charlotta Johansson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic Engineering; Trafikteknik;

    Sammanfattning : The content of this thesis is safety and mobility of children crossing streets as pedestrians and bicyclists. The risk of fatal injury is higher for pedestrians and bicyclists, especially for children and elderly, than for other road users except motorcyclists. LÄS MER
