2. 1. Methods to quantify and qualify truck driver performance

   Author : Iulian Carpatorea; Slawomir Nowaczyk; Thorsteinn Rögnvaldsson; Wahde Mattias; Högskolan i Halmstad; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Driver performance; heavy-duty vehicle; fuel economy; fuel consumption; fuel prediction; truck driver;

   Abstract : Fuel consumption is a major economical component of vehicles, particularly for heavy-duty vehicles. It is dependent on many factors, such as driver and environment, and control over some factors is present, e.g. route, and we can try to optimize others, e. READ MORE

4. 2. Truck Steering System and Driver Interaction

   Author : Kristoffer K D Tagesson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steering system; active safety; driver behaviour; active steering; torque feedback; heavy trucks;

   Abstract : This thesis presents a compilation of methods to consider when mapping steering functions and results as vehicle dimensions change. It is concluded that some final tuning inevitably will be required as major changes are performed. It is however possible to create qualified starting points using a set of simple rules as presented.

5. 3. Detecting Driver Sleepiness

   Author : David Sandberg; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Driver sleepiness has been identified as one of the most prevalent factors in road crashes. Methods for online detection of driver sleepiness may help to prevent such sleepiness-related crashes.The main aims of this thesis have been to improve driver sleepiness detection and to further the understanding of how sleepiness impairs driving behavior.

6. 4. Optimal Truck Scheduling : Mathematical Modeling and Solution by the Column Generation Principle

   Author : Myrna Palmgren; Torbjörn Larsson; Niklas Kohl; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; optimisation; pickup and delivery problem; transportation; scheduling; column generation; integer programming; MATHEMATICS; MATEMATIK;

   Abstract : We consider the daily transportation problem in forestry which arises when transporting logs from forest sites to customers such as sawmills and pulp and paper mills. Each customer requires a specific amount of a certain assortment, and the deliveries to the customers can be made within time intervals, known as time windows. READ MORE

7. 5. Evaluating vehicle stability support systems by measuring, analyzing, and modeling driver behavior

   Author : Gustav M Markkula; Chalmers tekniska högskola; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; driver behavior; driver models; system evaluation; heavy trucks; driving simulators; active safety; electronic stability control;

   Abstract : This thesis presents an investigation of near-accident behavior of truck drivers, with and without support from an electronic stability control (ESC) system. A critical scenario, involving both collision avoidance and vehicle stabilization on a low-friction surface, was studied in a driving simulator. READ MORE
