1. Simulation Studies for Improved Efficiency in Road and Rail Freight Transports
Sammanfattning : The demand for road and rail freight transport continues to grow with the expanding economy, while the climate crisis requires reduction in greenhouse gas emissions. Therefore, tools and solutions for reducing fossil fuel use and enabling more efficient use of infrastructure are needed. LÄS MER
2. Timetable Analysis based on Social Cost and Simulation
Sammanfattning : The timetable is essential for railway traffic. Its design affects rail operations – and by extension all operators, passengers, and freight clients. International practice for capacity allocation varies and there is no common algorithm for designing and evaluating timetable changes. LÄS MER
3. Timetable evaluation with focus on quality for travellers
Sammanfattning : Punctuality and reliability are important for travellers. Railway lines with heterogeneous and dense traffic have proved to be prone to generate delays. Faster services and increased traffic have to be counterbalanced with measures for increased reliability. Efficient timetable planning can improve the use of such lines. LÄS MER
4. Anisotropy in pearlitic steel subjected to rolling contact fatigue - modelling and experiments
Sammanfattning : In rails and wheels subjected to severe rolling/sliding contact, large plastic deformations accumulate in the surface layer. This decreases the fatigue resistance of components and makes this layer prone to formation of common rolling contact related defects. LÄS MER
