1. Foliated Transportation Networks - Evaluating feasibility and potential
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
2. Foliated Transportation Networks - Exploring feasibility and potential
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
3. Transportation Mission Based Optimization of Heavy Vehicle Fleets including Propulsion Tailoring
Sammanfattning : Over decades freight vehicles were produced for a wide range of operational domains so that vehicle-manufacturers were not concerned much about the actual use-cases of the vehicles. Environmental issues, costumer expectations along with growing demand on freight transport created a competitive environment in providing better transportation solutions. LÄS MER
4. Transportation Mission-Based Optimization of Heavy Combination Road Vehicles and Distributed Propulsion, Including Predictive Energy and Motion Control
Sammanfattning : This thesis proposes methodologies to improve heavy vehicle design by reducing the total cost of ownership and by increasing energy efficiency and safety. Environmental issues, consumers expectations and the growing demand for freight transport have created a competitive environment in providing better transportation solutions. LÄS MER
5. On Battery Electric Vehicles: Driving Patterns, Multi-Car Households and Infrastructure
Sammanfattning : The transportation sector is responsible for a quarter of all greenhouse gas emissions in Europe. Though the transport system may be difficult to change into a less polluting system, electric vehicles may be a possible approach. LÄS MER
