  2. 1. 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

  4. 2. 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

  5. 3. Heterogeneous goods in transportation systems

    Author : Per-Olof Arnäs; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; object-orientation; heterogeneous goods; transportation; complexity; systems science;

    Abstract : 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. READ MORE

  6. 4. Freight Transportation Operations and Information Sharing

    Author : Henrik Sternberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; RFID; Logistics; Information sharing; Information systems; Transportation;

    Abstract : Freight transportation operations are becoming increasingly complex due to an escalating number of actors and infrastructure capacity bottlenecks. Today’s transportation operations rely on static procedures instead of being actively controlled to achieve effective synchronization of the actors’ operations, resulting in slow responses to events and long waiting times in the transportation setup.

  7. 5. Complexity in transportation and logistics systems : A conceptual approach to modelling and analysis

    Author : Jonas Waidringer; Chalmers; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; management; measurement; logistics; modelling; complexity; transportation;

    Abstract : The basis for the thesis is to assess the usefulness of describing and analysing transportation and logistics systems as being complex systems. The reason and assumption being that in the future more integrated and sophisticated systems and solutions will be demanded. READ MORE
