16. Analysis of traffic load effects an railway bridges
Sammanfattning : The work presented in this thesis studies the load and loadeffects of traffic loads on railway bridges. The increasedknowledge of the traffic loads, simulated using fieldmeasurements of actual trains, are employed in a reliabilityanalysis in an attempt at upgrading existing railwaybridges. LÄS MER
17. Modelling and Simulation of Train-Track Interaction including Wear Prediction
Sammanfattning : Many problems in railway traffic arise as a result of the dynamic interaction between rolling trains and tracks. The problems include both instantaneous effects due to induced vibrations of track and vehicle, and more long-term processes of a detrimental nature. LÄS MER
18. Flexible Automation in Air Traffic Control Through Adaptation of Human-Automation Collaboration
Sammanfattning : Many domains currently experience an increase in level of automation of their technical systems. However, the increased level of automation must be accompanied with the development of well-functioning human-automation collaboration to avoid undesirable phenomena such as automation surprises or reduced situational awareness.

19. Train-Induced Ground Vibration and Its Prediction
Sammanfattning : This thesis based on a series of ground vibrationmeasurements at different sites presents two differentsemi-empirical models for prediction of ground-borne vibrationdue to train traffic. Ground-borne vibration due to train traffic may causeannoyance to people who live nearby the track or interfere withthe operation of sensitive equipment inside the buildings. LÄS MER
20. Assessment of Robustness in Railway Traffic Timetables
Sammanfattning : A tendency seen for the last decades in many European railway networks is a growing demand for capacity. An increased number of operating trains has led to a delay sensitive system where it is hard to recover from delays, where even relatively small delays are easily propagating to other traffic.
