  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. 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

  6. 4. Intermodal Road-Rail Transportation for Express Transport Services

    Author : Sofia Ohnell; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transport services; Intermodal transportation; transport systems; modelling; express transportation;

    Abstract : Express transport services are produced in highly modularised transport systems, a fact that implies that one subsystem can be exchanged for another without causing a need for major changes in other parts of the system. Express goods are not common on a large scale in freight railway transport systems, as those are often not considered reliable enough for time-critical goods. READ MORE

  7. 5. Modelling and Simulating Demand-Responsive Transport

    Author : Sergei Dytckov; Jan A. Persson; Paul Davidsson; Erik Jenelius; Malmö universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; On-Demand Mobility; Demand Responsive Transport; Modelling and Simulation; Sustainability;

    Abstract : Public transport is an efficient way to transport large volumes of travellers. However, there are systemic issues that make it hard for conventional public transport to provide efficient service on finer levels, like first- and last-mile problems or low-demand areas. READ MORE
