  1. 21. Reducing the effects of driver distraction : a comparison of distraction alerts on driver attention

    Författare :Lisbeth Almén; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : With the advancement of technology the traffic environment is becoming increasingly complex. Not only is there an increase in the number of in-vehicle displays and systems that are installed or brought into the car, there is also an increasing number of vehicles as well as other road users and messages on the road.

  3. 22. Energy Consumption and Running Time for Trains : modelling of running resistance and driver behaviour based on full scale testing

    Författare :Piotr Lukaszewicz; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy consumption; Running time; running resistance; driver behaviour; freight; train; energy coasting method; aerodynamic drag; driver model; degree of coasting; slippage; wind; Energy saving; braking ratio; powering ratio; full scale testing; Vehicle engineering; Farkostteknik;

    Sammanfattning : The accuracy in determined energy consumption and runningtime of trains, by means of computer simulation, is dependent upon the various models used. This thesis aims at developing validated models of running resistance, train and of a generaldriver, all based on full scale testing. LÄS MER

  4. 23. Speed characteristics of urban streets based on driver behaviour studies and simulation

    Författare :Karin F. M. Aronsson; Karl-Lennart Bång; Bengt Holmberg; KTH; []
    Nyckelord :Speed; Characteristics; Urban area; Road network; Street; Traffic; Driver; Side-friction element; Driving simulator; Simulation; Measurement; Behaviour; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The objective of the study was to gain in-depth knowledge of speed relationships for urban streets. The speed characteristics were examined using a number of methods for data collection. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  7. 25. Truck Steering System and Driver Interaction

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

    Sammanfattning : 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.
