2. 1. Passenger Car Wheel Aerodynamics

   Author : Christoffer Landström; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; tyres; wind tunnel; Passenger car aerodynamics; ground simulation; wheel rotation; drag; wheels;

   Abstract : Current and future requirements for efficiency force the automotive industry to consider all aspects of reducing the energy consumption of road going vehicles. An important aspect of reducing fuel consumption is reduced aerodynamic drag, which at highway cruising speeds is dominating the total drag force for both cars and heavy goods vehicles. READ MORE

4. 2. Passenger assessments of quality in local public transport- measurement, variability and planning implications

   Author : Helena Sjöstrand; Trafik och väg; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; passenger; public transport; quality; survey; Stated Preference; assessment; assignment; planning; Transportteknik; Transport technology; Road transport technology; Vägtransportteknik;

   Abstract : The aim of this work was to get a more detailed basis for planning of local public transport. With more knowledge of how segments of travellers assess different parts of a journey, bus routes can be planned to fit either all passengers or selected groups better. READ MORE

5. 3. Human aspects on the evacuation of a passenger ship - passengers' and crew's capabilities and limitations to cope with a dangerous and demanding situation

   Author : Monica Andersson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stress; passenger groups; reactions; passenger ships; group reactions; evacuation;

   Abstract : Todays evacuation systems and equipment are not adapted to realistic circumstances. The equipment is complicated, difficult and dangerous to handle. The equipment is furthermore tested and approved in limited weather conditions which make it more or less impossible to launch the equipment, if the weather conditions are too bad. READ MORE

6. 4. Evaluation of passenger train concepts : Methods and results of measuring travellers' preferences in relation to cost

   Author : Karl Kottenhoff; KTH; []
   Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : Politicians would like the railways to help to solve futuretransport and environmental problems. People can travel to andfrom work and on business during the day on modern trains whichare faster than any other alternative on journeys ofintermediate length. READ MORE

7. 5. Tyre aerodynamics of passenger vehicles

   Author : Erik Josefsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; drag; wind tunnel; tyres; aerodynamics; wheels;

   Abstract : To decelerate climate change and limit global warming, there is a need for reducing the environmental impact of vehicles, which can be achieved by increasing their energy efficiency. For a passenger vehicle, one of the largest resistive forces is aerodynamic drag. READ MORE
