  3. 2. Management of condition information from railway punctuality perspectives

    Författare :Rikard Granström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Sammanfattning : Due to the increasing need for transportation and environmental concerns, there is a social and political will to transfer transportation services from roads to rail. The increasing demand for railway transportation services has a significant effect on important stakeholder requirements, such as safety, punctuality, dependability, sustainability and costs.

  4. 3. Green Logistics through Modal Shift - exploring the role of the transport capacity contract

    Författare :Fredrik Eng Larsson; Teknisk logistik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; green logistics; modal shift; mode choice; capacity management; supply chain contracting; intermodal transport;

    Sammanfattning : Among policy-makers in Europe the modal shift - a shift från polluting modes of freight transport to less polluting modes - has been a popular suggestion for reducing CO2-emissions of transportation. In particular, intermodal road-rail solutions, where a combination of road and rail transport is utilized to move trailers and containers, have been stressed as an important measure to reach de desired reduction in emissions.

  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.
