2. 16. Fatigue of Asphalt Mixes - Theory of Viscoelasticity and Continuum Damage Mechanics Applied to Uniaxial Fatigue Data from Laboratory Tests

   Author : Richard Nilsson; Trafik och väg; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; asphalt mixture; viscoelastic; Fatigue; deterioration models; Continuum Damage Mechanics; laboratory test; uniaxial; hydraulic engineering; Civil engineering; offshore technology; soil mechanics; Väg- och vattenbyggnadsteknik;

   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.

4. 17. Rut Depth Prediction on Flexible Pavements - Calibration and Validation of Incremental-Recursive Models

   Author : Sven Agardh; Trafik och väg; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; offshore technology; Civil engineering; hydraulic engineering; Teknik; Technological sciences; PM-system; deterioration models; rutting; pavement design; soil mechanics; Väg- och vattenbyggnadsteknik;

   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

5. 18. Simulation Studies of Impact of Heavy-Duty Vehicle Platoons on Road Traffic and Fuel Consumption

   Author : Ingrid Johansson; Xiaoliang Ma; Wilco Burghout; Henrik Pettersson; Xiaobo Qu; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heavy-duty vehicle platooning; microscopic traffic simulation; intelligent transport systems; optimal control; longitudinal cruise control; fuel economy; Transportvetenskap; Transport Science;

   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

6. 19. Wheelchair Passengers and Local Public Transport Vehicles: Perceptions of Safety and Comfort

   Author : Anders Wretstrand; Trafik och väg; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road transport technology; Public transport; Bus; STS; Perception; Comfort; Wheelchair users; Safety; Vägtransportteknik; Care and help to handicapped; Handikappade; vård och rehabilitering;

   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

7. 20. Extended target tracking using PHD filters

   Author : Karl Granström; Thomas Schön; Fredrik Gustafsson; Ba-Ngu Vo; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The world in which we live is becoming more and more automated, exemplified by the numerous robots, or autonomous vehicles, that operate in air, on land, or in water. These robots perform a wide array of different tasks, ranging from the dangerous, such as underground mining, to the boring, such as vacuum cleaning. READ MORE
