    Sammanfattning : Background: The relevance of conducting this thesis is evident by the fact that bus and coach casualties have been “stubbornly stable” in Europe recent years and a need for investigating if a similar trend could be found in Sweden is therefore obvious. It was also important to add new knowledge to the bus and coach research in Sweden, since many areas were scarcely addressed. LÄS MER

  3. 2. Dwell time delays for commuter trains : An analysis of the influence of passengers on dwell time delays

    Författare :Ruben Kuipers; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dwell time; Passengers; Delays; Trains; Railway; Station; Automatic passenger count data;

    Sammanfattning : The thesis presented here delves into why dwell time delays for commuter trains occur, with a specific focus on the impact of boarding and alighting passengers. The overarching aim is to develop knowledge of how time delays arise to identify and describe potential ways in which dwell time delays can be reduced. LÄS MER

  4. 3. Wheelchair Passengers and Local Public Transport Vehicles: Perceptions of Safety and Comfort

    Författare :Anders Wretstrand; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road transport technology; Public transport; Bus; STS; Perception; Comfort; Wheelchair users; Safety; Vägtransportteknik; Care and help to handicapped; Handikappade; vård och rehabilitering;

    Sammanfattning : Eliciting wheelchair-seated passengers’ perspective of safety and comfort is both useful and mandatory, particularly for researchers, clinicians, transit authorities, and for operators during purchase and use of vehicle technologies in existing and planned future transport systems. Therefore, the overarching objective of this thesis was to delineate the question of safety and comfort as perceived by wheelchair-seated passengers using public transport road vehicles. LÄS MER

  5. 4. Odour-mediated nectar foraging in the silver Y moth, Autographa gamma

    Författare :Dainius Plepys; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; predation risk; Noctuidae; Lepidoptera; flight tunnel; GC-EAD; single sensillum; sprayer; ultrasound; floral volatiles; attraction; foraging; mate-finding; lilac aldehydes; olfactory receptor neurones; Ecology; Ekologi; Chemistry; Kemi;

    Sammanfattning : It is well established that floral odours play a significant role in the nectar foraging behaviour in Lepidoptera and other insect orders. Floral odour may elicit searching, alighting and feeding behaviours alone or in concert with visual stimuli. LÄS MER
