  2. 11. Active school transportation : Understanding the parental decision-making process

    Author : Hanna Forsberg; Stina Rutberg; Anna-Karin Lindqvist; Lars Nyberg; Maria Hagströmer; Luleå tekniska universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Active commuting to school; children; health promotion; parents; theory of planned behavior; physical activity; social norms; Physiotherapy; Fysioterapi;

    Abstract : Few children and adolescents reach the recommended levels of daily physical activity. This trend is evident in the countries examined in this thesis: Sweden and Spain. READ MORE

  4. 12. A Method to Identify Future Potential of Vehicle Safety Technology

    Author : Johan Strandroth; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; future crashes; collision avoidance; evaluation; autonomous braking; Delta-v; active safety; vehicle safety technology; CPR;

    Abstract : In the design of a safe road transport system there is a need to better understand the safety challenges lying ahead. One way of doing that is to evaluate safety technology with retrospective analysis of real world crashes. However, by using retrospective data there is the risk of adapting safety innovations to scenarios irrelevant in the future. READ MORE

  5. 13. Tracking Theory for Preventive Safety Systems

    Author : Lars Danielsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vehicle tracking; sensor data fusion; automotive; active safety systems; sensor models; warning integration; motion models; fusion strategies; human machine interface; preventive safety systems;

    Abstract : Preventive safety systems rely on accurate information from a sensing system regarding the current traffic situation to make decision whether to inform, warn or intervene to avoid an impeding collision or to mitigate its consequences. This thesis mainly considers tracking algorithms to enhance these systems through making the best use of the information supplied by on-vehicle sensors, such as radar and vision sensors. READ MORE

  6. 14. Parallel design optimization of multi-trailer articulated heavy vehicles with active safety systems

    Author : Manjurul Islam; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active safety systems; Active trailer steering; Multi-trailer articulated heavy vehicles; High performance computing; Design optimization;

    Abstract : Multi-trailer articulated heavy vehicles (MTAHVs) exhibit unstable motion modes at high speeds, including jack-knifing, trailer swing, and roll-over. These unstable motion modes may lead to fatal accidents. On the other hand, these vehicle combinations have poor maneuverability at low speeds. READ MORE

  7. 15. Indicators for traffic safety assessment and prediction and their application in micro-simulation modelling : a study of urban and suburban intersections

    Author : Jeffery Archer; Karl-Lennart Bång; Oliver Carsten; KTH; []
    Keywords : Social sciences; Traffic safety; proximal safety indicators; micro-simulation; safety analysis; Samhällsvetenskap; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Abstract : In order to achieve sustainable long-term transport infrastructure development, there is a growing need for fast, reliable and effective methods to evaluate and predict the impact of traffic safety measures. Recognising this need, and the need for an active traffic safety approach, this thesis focuses on traffic safety assessment and prediction based on the use of safety indicators that measure the spatial and/or temporal proximity of safety critical events.
