16. Data-driven Train Delay Prediction
Abstract : In Sweden, extensive use and the inherent heterogeneity of train traffic have significantly increased the sensitivity of the train system so that the delay of one train can easily propagate to others. Repeated experiences with train delays can lead passengers to perceive that railway transportation is unreliable. READ MORE

17. Fatigue of Asphalt Mixes - Theory of Viscoelasticity and Continuum Damage Mechanics Applied to Uniaxial Fatigue Data from Laboratory Tests
Abstract : The advance of analytic (mechanistic) design methods increases the need for fundamental material properties. Fatigue cracking due to traffic loading, in combination with permanent deformation (rutting), thermal cracking, irregularities, frost heave and reflective cracking are some of the major criteria used when designing an asphalt concrete pavement.

18. Rut Depth Prediction on Flexible Pavements - Calibration and Validation of Incremental-Recursive Models
Abstract : In later years the development of pavement design has gone towards more and more analytically based methods. Future design will probably be based on incremental deterioration models. The objective is to evaluate different types of rut depth prediction models for an incremental design process. READ MORE

19. Simulation Studies of Impact of Heavy-Duty Vehicle Platoons on Road Traffic and Fuel Consumption
Abstract : The demand for road freight transport continues to grow with the growing economy, resulting in increased fossil fuel consumption and emissions. At the same time, the fossil fuel use needs to decrease substantially to counteract the ongoing global warming. READ MORE

20. Wheelchair Passengers and Local Public Transport Vehicles: Perceptions of Safety and Comfort
Abstract : Eliciting wheelchair-seated passengers’ perspective of safety and comfort is both useful and mandatory, particularly for researchers, clinicians, transit authorities, and for operators during purchase and use of vehicle technologies in existing and planned future transport systems. Therefore, the overarching objective of this thesis was to delineate the question of safety and comfort as perceived by wheelchair-seated passengers using public transport road vehicles. READ MORE
