  2. 1. 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. 2. Railway Infrastructure Robustness : Attributes, evaluation, assurance and improvement

    Author : Per Norrbin; Ragnar Hedström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance Engineering;

    Abstract : According to the European program Horizon 2020, multifaceted challenges in transportinfrastructure include 1) making infrastructure more resilient to keep pace with the increasing mobility needs; 2) reducing the impact of infrastructure on the environment;and 3) dealing with declining resources to maintain and upgrade transport infrastructure. New design and maintenance approaches must be developed to handle these issues, ascurrent methods are inadequate. READ MORE

  5. 3. Interpretation of Railway Track Alignment Measurements in a Geodynamic Perspective

    Author : Jonas Majala; Jan Laue; Thorkild Maack Rasmussen; Kenneth Viking; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic load; Railway; Frequency; Track measurement; Geoteknik; Soil Mechanics;

    Abstract : The development in society means that infrastructure like ballasted railway systems are facing challenges due to request for increased number of high-speed trains and heavier freight trains. This implies that ballasted railways get an increased impact from larger dynamic loads. READ MORE

  6. 4. Accident Risk and Environmental Assessment : Development of an Assessment Guideline with Examination in Northern Scandinavia

    Author : Markus Lundkvist; Lennart Strömquist; Christer Jonasson; Rolf Nyberg; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geography; accident; risk; hazard; environmental assessment; geomorphology; railway; road; avalanche; debris flow; rock fall; slush flow; torrent; moose; reindeer; environmental impact assessment; proposal alternatives; Kiruna; Narvik; Geografi; Other earth sciences; Övrig geovetenskap;

    Abstract : In environmental impact assessment (EIA), accident risk should be considered as one impact. However, few studies have compared assessed risk levels with documented accidents. There is thus a need for assessing accuracy of risk assessment methodologies. READ MORE

  7. 5. Railway track dynamic modelling

    Author : Blas Blanco; Leif Kari; Stefano Bruni; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Track modelling; Timoshenko element; local deformation; response discontinuity; distributed supports; Engineering Mechanics; Teknisk mekanik;

    Abstract : The railway vehicles are an increasing mean of transportation due to, its reduced impact on environment and high level of comfort provided. These reasons have contributed to settle a positive perception of railway traffic into the European society. READ MORE
