  1. 1. Train crashes : consequences for passengers

    Författare :Rebecca Forsberg; Ulf Björnstig; Britt-Inger Saveman; Inggard Lereim; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Accident; crash; disaster; experiences; injuries; injury inducing objects; media coverage; railway; safety;

    Sammanfattning : Background: Globally, and in Sweden, passenger railway transport is steadily increasing. Sweden has been relatively free from severe train crashes in the last decades, but the railway infrastructure is alarmingly worn and overburdened, which may be one reason for an increasing number of reported mishaps.

  2. 2. Future Train Traffic Control : Development and deployment of new principles and systems in train traffic control

    Författare :Gunnika Isaksson-Lutteman; Bengt Sandblad; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap med inriktning mot människa-datorinteraktion; Computer Science with specialization in Human-Computer Interaction;

    Sammanfattning : The train traffic control system of the future requires new solutions and strategies in order to better meet tomorrow’s demands and goals. Uppsala University and Trafikverket have been collaborating for several years in research regarding train traffic control and how to improve traffic controllers’ support systems and working environment.

  3. 3. Train your brain : updating, transfer, and neural changes

    Författare :Erika Dahlin; Lars Nyberg; Anna Stigsdotter Neely; Torkel Klingberg; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; cognitive training; executive functioning; transfer; fMRI; brain system; young adults; elderly; practice; neural correlates; individual differences; Experimental brain research; Experimentell hjärnforskning; Cognitive science; Kognitionsforskning; fysiologi; Physiology;

    Sammanfattning : An initial aim of this thesis was to determine whether training of a specific executive function (updating) produces improvements in performance on trained and transfer tasks, and whether the effects are maintained over time. Neural systems underlying training and transfer effects were also investigated and one question considered is whether transfer depends on general or specific neural overlap between training and transfer tasks.

  4. 4. Challenges with Driverless and Unattended Train Operations

    Författare :Emil Jansson; Oskar Fröidh; Nils O.E. Olsson; Ingrid Johansson; Carl-William Palmqvist; Olov Lindfeldt; Ronghui Liu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway; Automatic train operation; Driverless trains; Train driver; Roles; Automation challenges; Human senses; Trackside sensors; Transportsystem; Transport Systems; Transportvetenskap; Transport Science;

    Sammanfattning : Demand for transportation continues to increase, for both freight and passenger services. One of the most energy-efficient modes of transportation is rail. One solution to increase the attractiveness of rail transport is to introduce automatic train operation (ATO) with a high grade of automation (GoA). LÄS MER

  5. 5. Data-driven Train Delay Prediction

    Författare :Kah Yong Tiong; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine learning; Predictive models; Data-driven; Railways; Train Delays;

    Sammanfattning : In Sweden, extensive use and the inherent heterogeneity of train traffic have significantly increased the sensitivity of the train system so that the delay of one train can easily propagate to others. Repeated experiences with train delays can lead passengers to perceive that railway transportation is unreliable. LÄS MER
