  2. 21. The GMOC Model : Supporting Development of Systems for Human Control

    Author : Simon Tschirner; Bengt Sandblad; Anders Jansson; Sebastiaan Meijer; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Human-Computer Interaction; User-Centered Design; Human Control; Train Traffic Control; Usability; System Development; Human Work; Railway Traffic; Rail Human Factors; Mental Models; Situation Awareness; Datavetenskap med inriktning mot människa-datorinteraktion; Computer Science with specialization in Human-Computer Interaction;

    Abstract : Train traffic control is a complex task in a dynamic environment. Different actors have to cooperate to meet strong requirements regarding safety, punctuality, capacity utilization, energy consumption, and more. The GMOC model has been developed and utilized in a number of studies in several different areas. READ MORE

  4. 22. Simulation of Surrounding Vehicles in Driving Simulators

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

    Abstract : 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. READ MORE

  5. 23. Learning for safety in health care and air traffic control

    Author : Sven Ternov; Ergonomi och aerosolteknologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Risk management; accident models; complex systems; health care; air traffic control; MTO analysis; DEB-analysis; proactive risk analysis.;

    Abstract : Introduction Risk management in enterprises, organisations and companies has had a long and complicated history. During the eighties, and at least during the beginning of the nineties, the notion concerning risk management was that if an accident happened in an otherwise perfect system it was due to the human operator in some way being the cause of the error.

  6. 24. Emission estimation based on traffic models and measurements

    Author : Nikolaos Tsanakas; Jan T. Lundgren; Joakim Ekström; Johan Olstam; Marcus Gerstenberger; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Traffic congestion increases travel times, but also results in higher energy usage and vehicular emissions. To evaluate the impact of traffic emissions on environment and human health, the accurate estimation of their rates and location is required. READ MORE

  7. 25. Sensitivity analysis methods for road traffic emission models

    Author : Olle Eriksson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Abstract : Many systems, and some of their properties, are studied in simulation models. The models may be very complex and difficult to understand if the systems they are meant to simulate are complex in themselves. Even small, simple and well-described models can have properties that cannot easily be seen in the model formulations. READ MORE
