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

    Author : Joakim Kalantari; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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;

    Abstract : 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. READ MORE

  4. 2. Sustainable Electromobility : A System Approach to Transformation of Transportation

    Author : Harrison John Bhatti; Mike Danilovic; Rune Wigblad; Statens väg- och transportforskningsinstitut; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Energy system; Transportation System; System Approach; Symbiotic Business Model; Innovation Ecosystem; Technology Readiness; Political Readiness; Societal Readiness; Economic Readiness;

    Abstract : This thesis aims to explore, analyze, and develop knowledge that leads to an understanding of identifying the key actors and their symbiotic relationships and dependencies in transforming the energy and transportation system from fossil-based to renewable and fossil fuel-powered vehicles to electric. The research was explorative and categorized into two studies.

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

    Author : Joakim Kalantari; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

  7. 5. Energy efficiency improvements in logistics as a means to environmental sustainability: The case of capacity utilisation in road freight transportation

    Author : Jessica Wehner; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Capacity utilisation; household logistics capability; system levels; distribution structure; logistics system; energy efficiency; last-mile fulfilment; overcapacity; system boundaries; road freight transportation;

    Abstract : The energy consumption in logistics, and especially in road freight transportation, is steadily increasing and with that the greenhouse gas emissions which have a negative impact on the environment. In order to improve environmental sustainability of logistics, a change in the actors’ behaviour and policies is needed since the development of technology alone is not sufficient. READ MORE
