11. Wheelchair Passengers and Local Public Transport Vehicles: Perceptions of Safety and Comfort
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
12. Large-Eddy Simulation for Computing the Flow Around Vehicles
Sammanfattning : The feasibility of the use of large-eddy simulation (LES) in external vehicle aerodynamics is investigated. The computational requirement for LES of the full size car at road conditions is beyond the capability of computers in the near future. Since LES cannot be used for quantitative prediction of this flow, i.e. LÄS MER
13. Competition in Public Transport : Essays on competitive tendering and open-access competition in Sweden
Sammanfattning : The results of this work show that the cost efficiency of tendered bus services is similar across all Swedish counties, except for the more high-density counties where efficiency is lower. Considerably lower efficiency is also found for contracts with services run in-house by the Public Transport Authority (PTA), compared to when the same service is run by a private actor. LÄS MER
14. Barns samspel bortom förskolans väggar : Om yngre barns samspel och platsskapande på förskolegården och i en mobil förskola
Sammanfattning : The general aim of this thesis is to explore the relations between children’s interaction and places within preschool activities. How children’s interaction opportunities are conditioned by the physical and social environment in the preschool yard (study I), as well as place-making processes in various contexts in mobile preschool activities (studies II and III), are examined within the framework of this purpose.
