    Författare :Harsha Cheemakurthy; Karl Garme; Joakim Kalantari; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; waterborne public transportation; commuter ferry; modular design; operational requirements; ranking method; sustainable performance; ice operations; ice-hull Interaction; ice load; ice properties; kollektivtrafik på vatten; modulärt färjekoncept; modulär design; rankningsmetod; hållbarhetsparametrar; isbelastning; isförhållanden; isegenskaper; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : There has been a recent surge in interest in waterborne public transportation (WPT). Publictransport providers (PTP) are seeing its potential in complementing the existing transportnetwork and alleviating urban traffic congestion and pollution. But the adoption of WPTtoday is challenging due to a series of technical and implementation challenges. LÄS MER

  4. 3. 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

  5. 4. An infrastructure of freedom : Atlanta, race, and the struggle over public transportation in the capitalist city

    Sammanfattning : This thesis provides a multiscalar analysis of the production and struggle over the Metropolitan Atlanta Rapid Transit Authority (MARTA), the main transit system in metro Atlanta. It examines how the actions and visions of the state, capital, and transportation activists intersect to structure how and to what extent transit systems can be organized to realize their distinctive potential to allow urban residents to meet their basic mobility needs.
