1. Energy Consumption and Running Time for Trains : modelling of running resistance and driver behaviour based on full scale testing
Sammanfattning : The accuracy in determined energy consumption and runningtime of trains, by means of computer simulation, is dependent upon the various models used. This thesis aims at developing validated models of running resistance, train and of a generaldriver, all based on full scale testing. LÄS MER
2. 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
3. Long freight trains and long-term rail surface damage
Sammanfattning : Track damage due to progressively increasing tonnage, especially due to longer and heavier freight trains, is one of the major problems faced in the European rail sector. In this context, to stay competitive, optimal track maintenance practices, track-friendly vehicles and safe operations of long freight trains assume prominence. LÄS MER
4. Access management for road hauliers and rail operators in intermodal freight terminals
Sammanfattning : A pivotal element in the transport industry, intermodal freight transport, is rather complex due to the numerous transport modes and actors involved. Terminal operators in intermodal freight transport face major challenges to provide seamless flows of containers via their terminals. LÄS MER
5. Development of Small-Scale Intermodal Freight Transportation in a Systems Context
Sammanfattning : An intermodal freight transportation system is characterised by the subsequent use of different transportation modes for moving goods stowed into unit loads from the consignor to the consignee. Typically, it involves a wide variety of activities, actors and resources, which implies a certain degree of technological as well as organisational complexity. LÄS MER
