    Sammanfattning : This thesis discusses the implications of research-based decision-making to develop socially robust technologies, policies, and urban planning in the transport sector, aiming for an inclusive and more sustainable transport system. What are the travel patterns of both users and non-users of car sharing and private cars in European cities? What are the main psychological aspects of and motives for making a travel mode choice? Study I presents a classification of motives considered as relevant when selecting a mode of transport, and it examines the relative importance of driving habits, car attitudes, descriptive norms, and motives for transport mode choices for commuting, shopping trips, child-related trips, and leisure trips.

  3. 2. Neighborhood Design and Travel : a Study of Residential Quality, Child Leisure Activity and Trips to School

    Författare :Pia Westford; Dick Urban Vestbro; Anders Hagson; KTH; []
    Nyckelord :urban design; neighborhood; car use; child leisure activity; school trips; lifestyle; perceived environment;

    Sammanfattning : Sustainable urban mobility calls for well-informed design of neighborhoods. Although many studies have been conducted in the field, there is little evidence about the relationships between design elements, urban quality and behavior. Little is also known about residents’ valuation of design and urban quality in this context. LÄS MER

  4. 3. Evaluation of the Random-LOS Measurement System for Vehicular Communication Applications

    Författare :Madeleine Schilliger Kildal; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reverberation Chamber; Over-the-Air; Anechoic Chamber; Random Line-of-Sight; Rich Isotropic Multipath; wireless communication; car measurements; throughput;

    Sammanfattning : The automotive industry is progressively closing on the Telecom industry as wireless data connection and transmission become more and more important for vehicles. In both future and present cars, the safety and infotainment systems depend on reliable wireless data transmission. This is especially the case when autonomous cars will reach the market. LÄS MER

  5. 4. Sound quality evaluation of heavy-duty engines in free field conditions

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

    Sammanfattning : Annoyance response to vehicle noise is commonly reported. The impact reduction measures must therefore be measured scientifically. A scientific system for describing and defining annoyance is therefore required. There is furthermore a need to reduce the annoying components of the sound of vehicles. LÄS MER

  7. 5. The simulation of car and truck tyre vibrations, rolling resistance and rolling noise

    Författare :Carsten Hoever; Chalmers tekniska högskola; []
