  2. 1. Having a New Pair of Glasses : Applying Systemic Accident Models on Road Safety

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

    Abstract : 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. READ MORE

  4. 2. Predictive models for accidents on urban links - A focus on vulnerable road users

    Author : Thomas Jonsson; Trafik och väg; []
    Keywords : 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;

    Abstract : 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.

  5. 3. The Effective Convectivity Model for Simulation and Analysis of Melt Pool Heat Transfer in a Light Water Reactor Pressure Vessel Lower Head

    Author : Chi Thanh Tran; Tomas Lefvert; Harri Tuomisto; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; light water reactor; hypothetical severe accident; accident progression; accident scenario; core melt pool; heat transfer; turbulent natural convection; heat transfer coefficient; phase change; mushy zone; crust; lower plenum; analytical model; effective convectivity model; CFD simulation; Thermal energy engineering; Termisk energiteknik;

    Abstract : Severe accidents in a Light Water Reactor (LWR) have been a subject of intense research for the last three decades. The research in this area aims to reach understanding of the inherent physical phenomena and reduce the uncertainties in their quantification, with the ultimate goal of developing models that can be applied to safety analysis of nuclear reactors, and to evaluation of the proposed accident management schemes for mitigating the consequences of severe accidents.

  6. 4. Development of traffic conflicts technique for different environments: A comparative study of pedestrian conflicts in Sweden and Jordan

    Author : Lina Shbeeb; Trafik och väg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; perception of conflicts.; non-signalised junctions; signalised junctions; accident prediction; accident to conflict conversion factors; TA-speed graphs; conflict speed; time to accidents; conflict sub-grouping; severity index; threshold; relevant road-user; pedestrian conflict; Traffic safety; traffic conflict technique; Technological sciences; Teknik; Social sciences; Samhällsvetenskaper;

    Abstract : This study is aimed at improving the current Swedish Traffic conflicts Technique [TCT] in relation to vehicle-pedestrian conflicts. The present definition of conflict severity appears to produce less severe conflicts than they might be, particularly if the relevant road user (RRU) is the pedestrian. READ MORE

  7. 5. The Prediction of Traffic Accident Involvement from Driving Behavior

    Author : Anders af Wåhlberg; Lennart Melin; Frank McKenna; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Psykologi; Psychology; Psykologi;

    Abstract : The aim of the studies was to predict individual traffic accident involvement by the quantification of driving style in terms of speed changes, using bus drivers as subjects. An accident database was constructed from the archives of the bus company whose drivers were used as subjects. READ MORE
