  1. 21. Facing failures : interactions between drivers and advanced driver assistance systems

    Författare :Niklas Strand; Håkan Alm; Statens väg- och transportforskningsinstitut; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adaptive cruise control; Driver assistance system; Driver; Behaviour; Thesis; Adaptiva farthållare; Förarstödssystem; Förare; Beteende; Doktorsavhandling; 841 Road: Road user behaviour; 841 Road: Road user behaviour; 914 Road: ITS och vehicle technology; 914 Road: ITS och vehicle technology; 911 Road: Components of the vehicle; 911 Road: Components of the vehicle;

    Sammanfattning : Drivers’ interactions with advanced driver assistance systems based on experiences from real driving and results from driving in a driving simulator were under investigation in this thesis. Questions posed were: - How do drivers perceive and interact with ADAS? - How are (technical) failures handled by drivers, and which are the consequences’ of these failures? - Which are the implications for diagnosis and detection of failures, as well as for system development? Special attention was given to driver behavior in response to technical failures in an adaptive cruise control system. LÄS MER

  2. 22. Cooperative Variable Speed Limit Systems : Modeling and Evaluation using Microscopic Traffic Simulation

    Författare :Ellen Grumert; Jan Lundgren; Andreas Tapani; Wilco Burghout; Statens väg- och transportforskningsinstitut; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 23. Multi-unit common value auctions : theory and experiments

    Författare :Joakim Ahlberg; Lars Hultkrantz; Jan-Eric Nilsson; Jerker Holm; Statens väg- och transportforskningsinstitut; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Multi-Unit Auction; Common Value Auction; Laboratory Experiment; Game Theory; Economics; Q Economics; Q Economics; Economics;

    Sammanfattning : Research on auctions that involve more than one identical item for sale was,almost non-existing in the 90’s, but has since then been getting increasing attention. External incentives for this research have come from the US spectrum, sales, the European 3G mobile-phone auctions,  and Internet auctions. LÄS MER

  4. 24. The development of methods for detection and assessment of safety critical events in car driving

    Författare :Omar Bagdadi; Andras Varhelyi; Nicolas Saunier; Statens väg- och transportforskningsinstitut; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Near miss; Braking; Driving veh ; Driver; Behaviour; Tillbud; Bromsning; Fordonskörning; Förare; Beteende; Road: Road user behaviour; Road: Road user behaviour; Crash involvement; jerk; safety critical event;

    Sammanfattning : Improving our knowledge of drivers’ behaviour, especially in hazardous situations is a key to understanding why accidents occur and how to improve safety on our roads. Crash surrogate measures have proven to be very useful in traffic safety analysis. LÄS MER

  5. 25. Simulation of Surrounding Vehicles in Driving Simulators

    Författare :Johan Olstam; Jan Lundgren; Jonas Jansson; Mikael Adlers; Pontus Matstoms; Martin Fellendorf; Statens väg- och transportforskningsinstitut; []
    Nyckelord :Traffic; Micro; Simulation; Mode; Overtaking; Lane changing; Car following; Rural road; Mathematical model; Simulator; Thesis; Road: Traffic theory; Road: Traffic theory; TECHNOLOGY;

    Sammanfattning : Driving simulators and microscopic traffic simulation are important tools for making evaluations of driving and traffic. A driving simulator is de-signed to imitate real driving and is used to conduct experiments on driver behavior. Traffic simulation is commonly used to evaluate the quality of service of different infrastructure designs. LÄS MER
