  1. 1. 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

  3. 2. Delays and Timetabling for Passenger Trains

    Författare :Carl-William Palmqvist; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rail; delay; timetable; train; punctuality; Rail transportation;

    Sammanfattning : Travel by train has increased steadily in Sweden the last 30 years. The pace has been about two to three percent per year, and we now have twice as many passengers. With growing awareness of the changing climate, the pace is increasing further. A problem that affects both passengers and businesses in Sweden is train delays. LÄS MER

  4. 3. Application of Predictive Analytics for Shunting Yard Delays

    Författare :Niloofar Minbashi; Markus Bohlin; Behzad Kordnejad; Carl-William Palmqvist; Paola Pellegrini; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shunting yards; train delays; machine learning; simulation; freight transport; Godsbangårdar; tåg förseningar; maskininlärning; simulering; godstransport; Transportsystem; Transport Systems;

    Sammanfattning : Increasing the modal share of rail freight transport is one of the main ways to achieve carbon neutrality in Europe. The perceived low reliability and predictability of rail freight services is one of the main challenges to overcome in reaching this target. LÄS MER

  5. 4. Applying Data Analytics to Freight Train Delays in Shunting Yards

    Författare :Niloofar Minbashi; Markus Bohlin; Behzad Kordnejad; Carl-William Palmqvist; C. Tyler Dick; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shunting yards; delay prediction; congestion; delay probability distributions; temporal delay distributions; Rangergodsbangårdarna; förseningsprediktion; trängsel; fördröjning av sannolikhetsdistributioner; tidsfördröjningsdistributioner; Transportsystem; Transport Systems;

    Sammanfattning : The European Commission has foreseen a modal share of 30% by 2030 for rail freight transport. To achieve this increase in the modal share, enhanced reliability of rail freight services is required. Optimal functioning of shunting yards is one of the areas that can improve this reliability.

  7. 5. Timetable evaluation with focus on quality for travellers

    Författare :Jennifer Warg; Markus Bohlin; Olsson Nils; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Capacity evaluation; railway simulation; economic assessment; delays; timetable analysis; Transportvetenskap; Transport Science;

    Sammanfattning : Punctuality and reliability are important for travellers. Railway lines with heterogeneous and dense traffic have proved to be prone to generate delays. Faster services and increased traffic have to be counterbalanced with measures for increased reliability. Efficient timetable planning can improve the use of such lines. LÄS MER
