  3. 12. Predictive models for accidents on urban links - A focus on vulnerable road users

    Författare :Thomas Jonsson; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road transport technology; Transportteknik; Transport technology; Teknik; Technological sciences; Stads- och glesbygdsplanering; Town and country planning; speed; links; urban; safety; vulnerable road users; modelling; prediction; crash; traffic safety; accident; Vägtransportteknik;

    Sammanfattning : Much of earlier work on predictive models for accidents has been focused on rural traffic or urban intersections. This work has aimed at identifying and investigating possible improvements to predictive models for accidents on urban links. A special focus has been on the accidents of vulnerable road users.

  4. 13. Fire safety design of road tunnels

    Författare :Jonatan Gehandler; Avdelningen för Brandteknik; []
    Nyckelord :HUMANIORA; HUMANITIES; Brandsäkerhet; vägtunnlar; design; Riskbedömning; Road tunnel fire safety; Fire safety engineering; design framework; risk evaluation;

    Sammanfattning : This thesis can be described as a journey in performance-based fire safety design. Along the way questions such as what fire safety is, how it can be measured, whether we are posing the right questions, or engineer the best solutions, have arisen. LÄS MER

  5. 14. Having a New Pair of Glasses : Applying Systemic Accident Models on Road Safety

    Författare :Yu-Hsing Huang; Erik Hollnagel; Pietro Carlo Cacciabue; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; accident model; road safety; accident prevention; accident analysis; Cognitive science; Kognitionsvetenskap;

    Sammanfattning : The main purpose of the thesis is to discuss the accident models which underlie accident prevention in general and road safety in particular, and the consequences of relying on a particular model have for actual preventive work. The discussion centres on two main topics. LÄS MER

  7. 15. Modelling and evaluation of the effects of traffic safety measures Comparative analysis of driving assistance systems and road infrastructure

    Författare :Meng Lu; Trafik och väg; []
