  1. 1. Evaluation and Modelling of Short Haul Intermodal Transport Systems

    Författare :Behzad Kordnejad; Sebastian Stichel; Bo-Lennart Nelldal; Sebastiaan Meijer; Johan Woxenius; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transportvetenskap; Transport Science;

    Sammanfattning : Conventional intermodal rail freight transport systems have proved themselves competitive and able to offer cost-leadership on long distances and in endpoint relations between two nodes. Several studies within intermodal transports have made contributions in finding the minimum distance, the “break-even” distance that an intermodal door-to-door shipment can compete with unimodal road.

  3. 2. Regional Intermodal Transport Systems : Analysis and Case Study in the Stockholm-Mälaren Region

    Författare :Behzad Kordnejad; Bo-Lennart Nelldal; Rickard Bergqvist; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Järnvägsgruppen - Effektiva tågsystem för godstrafik; Järnvägsgruppen - Effektiva tågsystem för godstrafik;

    Sammanfattning : The global trend of urbanization is evident and also valid in Sweden and for the Stockholm-Mälaren region, also referred to as the Mälaren valley, a region consisting of metropolitan Stockholm and areas around the lake of Mälaren. In this context, efficient urban freight transportation has emerged as essential for sustainable development of urban areas. LÄS MER

  4. 3. Simulation Studies for Improved Efficiency in Road and Rail Freight Transports

    Författare :Ingrid Johansson; Markus Bohlin; Oskar Fröidh; Behzad Kordnejad; Carl-William Palmqvist; C. Tyler Dick; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heavy-duty vehicle platooning; road traffic simulation; intelligent transport systems; optimal control; longitudinal cruise control; fuel economy; railway traffic simulation; microscopic simulation; macroscopic simulation; freight trains; early departures; capacity; railway stations; strategic planning; timetable compression; UIC Code 406; Transportsystem; Transport Systems;

    Sammanfattning : The demand for road and rail freight transport continues to grow with the expanding economy, while the climate crisis requires reduction in greenhouse gas emissions. Therefore, tools and solutions for reducing fossil fuel use and enabling more efficient use of infrastructure are needed. LÄS MER

  5. 4. 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

  7. 5. 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.
