2. 1. Motorists´evaluation of road maintenance management

   Author : Camilla Olsson; KTH; []
   Keywords : stated choice; stated preference; valuations of maintenance management; driving comfort; road standard evaluation;

   Abstract : The road network is extremely valuable. Road Administrationsare expected to invest maintenance funding in a way thatreturns maximum benefit to road users. Cost-benefit analysis isone method to ensure that an adequate return in terms ofbenefits results from committing expenditure. READ MORE

4. 2. Evaluation of Adapted Passenger Cars for Drivers with Physical Disabilities

   Author : Björn Peters; Statens väg- och transportforskningsinstitut; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Disabled person; Driver; Car; Adaptation; Equipment; Vehicle handling; Simulator; Adaptive cruise control; Driving aptitude; Thesis; 911 Road: Components of the vehicle; 911 Road: Components of the vehicle; 841 Road: Road user behaviour; 841 Road: Road user behaviour; 84 Road: Road users; 84 Road: Road users;

   Abstract : Driving can provide independent and efficient mobility. However, according to the driving license directive (91/439/EEC) are persons with locomotor impairments are only allowed drive if their disabilities can be compensated. Compensation can be realised by vehicle adaptations. READ MORE

5. 3. Cooperative Variable Speed Limit Systems : Modeling and Evaluation using Microscopic Traffic Simulation

   Author : Ellen Grumert; Jan Lundgren; Andreas Tapani; Wilco Burghout; Statens väg- och transportforskningsinstitut; []
   Keywords : Variable speed limit; Traffic; Micro; Simulation; Data exchange; Telecommunication; Vehicle; Transport infrastructure; Intelligent transport system; In vehicle information; 23 Road: ITS och traffic; 23 Road: ITS och traffic; 25 Road: Traffic theory; 25 Road: Traffic theory;

   Abstract : During the last decades the road traffic has increased tremendously leading to congestion, safety issues and increased environmental impacts. As a result, many countries are continuously trying to find improvements and new solutions to solve these issues. READ MORE

6. 4. Iterative Road Grade Estimation for Heavy Duty Vehicle Control

   Author : Per Sahlholm; Karl Henrik Johansson; Jonas Sjöberg; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; road grade; estimation; heavy duty vehicle; Kalman filter; automatic control; Automatic control; Reglerteknik;

   Abstract : This thesis presents a new method for iterative road grade estimation based on sensors that are commonplace in modern heavy duty vehicles. Estimates from multiple passes of the same road segment are merged together to form a road grade map, that is improved each time the vehicle revisits an already traveled route. READ MORE

7. 5. Predictive model of perceived driving stability at high speeds under aerodynamic excitations

   Author : Arun Kumar; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; driver-vehicle interaction; unsteady aerodynamics; Driving simulator; on-road tests; predictive model; vehicle stability; subjective evaluation;

   Abstract : The automotive industry is continuously advancing towards more energy-efficient vehicle designs.  Streamlined vehicles have low aerodynamic drag but have the potential to be unstable when  exposed to external excitations such as unsteady aerodynamic forces created by the flow of air  around them.
