2. 6. Driver behavior models for evaluating automotive active safety: From neural dynamics to vehicle dynamics

   Author : Gustav M Markkula; Chalmers tekniska högskola; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; simulation; active safety; control behavior; system evaluation; Driver models;

   Abstract : The main topic of this thesis is how to realistically model driver behavior in computer simulations of safety critical traffic events, an increasingly important tool for evaluating automotive active safety systems. By means of a comprehensive literature review, it was found that current driver models are generally poorly validated on relevant near-crash behavior data. READ MORE

4. 7. Mechanistic-Empirical Modelling of Flexible Pavement Performance : Verifications Using APT Measurements

   Author : Abubeker W. Ahmed; Sigurdur Erlingsson; Hervè Di Benedetto; Statens väg- och transportforskningsinstitut; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Performance; Deformation; Model not math ; Rutting wheel ; Viscoelasticity; Elasticity; Axle load; Flexible pavement; Laboratory not an organization ; Test; Thesis; Heavy vehicle simulator; Wheel tracking test; 32 Road: Pavement design; 32 Road: Pavement design; Transportvetenskap; Civil and Architectural Engineering;

   Abstract : Mechanistic-Empirical  (M-E)  pavement  design  procedures  are  composed  of  a  reliable  response model to estimate the state of stress in the pavement and distress models in order to predict the different types of pavement distresses due to the prevailing traffic and environmental conditions. One of the main objectives of this study was to develop a response model based on multilayer elastic  theory   (MLET)  with  improved  computational  performance  by   optimizing  the   time consuming parts of the MLET processes.

5. 8. Analyses of Resilient Behavior of Unbound Materials for the Purpose of Predicting Permanent Deformation Behavior

   Author : Jan Englund; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Permanent Deformation; Unbound Material; Resilient Deformation; Post Compaction; Falling Weight Deflectometer FWD ; Triaxial Testing; Heavy Vehicle Simulator HVS ; Modulus;

   Abstract : Post compaction is the unintended compaction of the unbound material that commences immediately after a road is brought into service and caused by densification of the material. Analogies to this post compaction can also be seen in laboratory and field tests. READ MORE

6. 9. On Path Planning and Path Following for Wheeled Mobile Robots

   Author : Ferenc Weiczer; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The aim of the research documented and discussed in this thesis is to develop navigation methods including Path Planning, Location Measurement, and Path Following for supporting the navigation of wheeled mobile robots (WMR). The concept provides methods for path planning, i.e. READ MORE

7. 10. Prediction of permanent deformations in asphalt concrete using the mechanistic-empirical pavement design guide

   Author : Erik Oscarsson; Trafik och väg; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; permanent deformation; design guide; asphalt concrete; mechanistic empirical;

   Abstract : Permanent deformations, or rutting, are internationally considered to be one of the most serious distress mechanisms in asphalt pavements. Deterioration modeling is an important tool for performance prediction and diagnostics of pavements. READ MORE
