1. Foliated Transportation Networks - Evaluating feasibility and potential
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

2. Foliated Transportation Networks - Exploring feasibility and potential
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

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

4. Freight Transportation Operations and Information Sharing
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.

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