  1. 1. Passenger Car Wheel Aerodynamics

    Författare :Christoffer Landström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; tyres; wind tunnel; Passenger car aerodynamics; ground simulation; wheel rotation; drag; wheels;

    Sammanfattning : Current and future requirements for efficiency force the automotive industry to consider all aspects of reducing the energy consumption of road going vehicles. An important aspect of reducing fuel consumption is reduced aerodynamic drag, which at highway cruising speeds is dominating the total drag force for both cars and heavy goods vehicles. LÄS MER

  3. 2. Passenger assessments of quality in local public transport- measurement, variability and planning implications

    Författare :Helena Sjöstrand; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; passenger; public transport; quality; survey; Stated Preference; assessment; assignment; planning; Transportteknik; Transport technology; Road transport technology; Vägtransportteknik;

    Sammanfattning : The aim of this work was to get a more detailed basis for planning of local public transport. With more knowledge of how segments of travellers assess different parts of a journey, bus routes can be planned to fit either all passengers or selected groups better. LÄS MER

  4. 3. Den riskfyllda gemenskapen : Att hantera säkerhet på ett passagerarfartyg

    Författare :Christer Eldh; Boel Berner; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; cultural processes; organization; gender; risk; safety culture; passenger ship; safety management; passagerarfartyg; säkerhetsaspekter; riskhantering; risk; fartyg; kulturella aspekter; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : The purpose of this study was to examine how cultural processes and organisational conditions influence safety management in complex sociotechnical contexts. The object of investigation was a passenger ship where interviews and observations had been conducted for one year. LÄS MER

  5. 4. Human aspects on the evacuation of a passenger ship - passengers' and crew's capabilities and limitations to cope with a dangerous and demanding situation

    Författare :Monica Andersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stress; passenger groups; reactions; passenger ships; group reactions; evacuation;

    Sammanfattning : Todays evacuation systems and equipment are not adapted to realistic circumstances. The equipment is complicated, difficult and dangerous to handle. The equipment is furthermore tested and approved in limited weather conditions which make it more or less impossible to launch the equipment, if the weather conditions are too bad. LÄS MER

  7. 5. Evaluation of passenger train concepts : Methods and results of measuring travellers' preferences in relation to cost

    Författare :Karl Kottenhoff; KTH; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Politicians would like the railways to help to solve futuretransport and environmental problems. People can travel to andfrom work and on business during the day on modern trains whichare faster than any other alternative on journeys ofintermediate length. LÄS MER
