  1. 1. 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

  3. 2. Timetable Analysis based on Social Cost and Simulation

    Författare :Jennifer Warg; Markus Bohlin; Oskar Fröidh; Carl-William Palmqvist; Paola Pellegrini; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway capacity allocation; timetable analysis; social costs; microscopic railway simulation; macroscopic railway simulation; passengers; timetable performance; early departing freight trains; Järnvägskapacitet; tidtabellsanalys; sociala kostnader; mikroskopisk järnvägssimulering; makroskopisk järnvägssimulering; resande; tidtabellseffektivitet; tidiga godståg; Transportsystem; Transport Systems;

    Sammanfattning : The timetable is essential for railway traffic. Its design affects rail operations – and by extension all operators, passengers, and freight clients. International practice for capacity allocation varies and there is no common algorithm for designing and evaluating timetable changes. LÄS MER

  4. 3. 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
