  1. 1. Foliated Transportation Networks - Evaluating feasibility and potential

    Författare :Joakim Kalantari; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; hybrid transportation systems; transportation network modeling; intelligent transportation systems.; transportation planning and control; transportation network simulation; transportation network optimization; Transportation networks; transportation network performance; mixed model transportation; transportation network efficiency;

    Sammanfattning : Neither the critical role that transportation plays for economic activities nor its negative external effects can be denied. At the same time, the resources required to sustain and develop the transportation system to an adequate degree and at the required pace are limited. LÄS MER

  3. 2. Foliated Transportation Networks - Exploring feasibility and potential

    Författare :Joakim Kalantari; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transportation network modeling; hybrid transportation systems; transportation network optimization; transportation network simulation; transportation planning and control; Transportation networks; mixed model transportation;

    Sammanfattning : In transportation systems in general the issue of overcapacity coupled with low resource utilization has been identified for some time now. It has also been shown that the growth in transportation demand in the past is not absorbed by the existing overcapacity; rather the low levels of resource utilization are maintained. LÄS MER

  4. 3. Energy transition in transportation : Applying TIMES-based energy system optimisation models to sub-national levels

    Författare :Jonas Forsberg; Anna Krook-Riekkola; Andrea Toffolo; Åsa Lindman; Krister Sandberg; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Energy system analysis; ESOM; Transportation; Climate change; Air quality; Energiteknik; Energy Engineering;

    Sammanfattning : Transportation is embedded in the fabric of society and a key enabler of socio-economic development, but it is also a major source of carbon dioxide (CO2) and local air pollution (AP). Cities collectively account for around three quarters of total energy-related CO2 emissions, and the negative health impacts from local APs are most felt in dense urban environments. LÄS MER

  5. 4. Heterogeneous goods in transportation systems

    Författare :Per-Olof Arnäs; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; object-orientation; heterogeneous goods; transportation; complexity; systems science;

    Sammanfattning : This thesis presents research regarding the impact differences in goods type have on the control of a transportation process. It also explores how the object-oriented family of methods are used and can be used in analysing and designing transportation systems. LÄS MER

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

    Författare :Marcus Mohall; Don Mitchell; David Jansson; Theresa Enright; Uppsala universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; public transportation; transit; transit struggles; transportation; planning; mobility; politics of mobility; transportation politics; infrastructure; capitalism; race; USA; US South; Atlanta; Social and Economic Geography; Kulturgeografi;

    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.
