  1. 1. 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

  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

  5. 4. Improving Timetable Robustness and Punctuality of Railway Traffic : A Combined Simulation-Optimization Approach for Nonperiodic Timetabling on Double-Track Lines

    Författare :Johan Högdahl; Markus Bohlin; Oskar Fröidh; Rob Goverde; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Timetabling; Train scheduling; Delay prediction; Punctuality; Railroad; Robustness; Transportsystem; Transport Systems;

    Sammanfattning : To evaluate the robustness of a timetable against minor delays, it can be simulated. A natural question following a simulation is how the results can be used to improve the timetable, which has received limited attention in the literature. LÄS MER

  7. 5. Parallel algorithms for solving the train timetable rescheduling problem

    Författare :Sai Prashanth Josyula; Johanna Törnquist Krasemann; Lars Lundberg; Blekinge Tekniska Högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Parallel computing; Parallel heuristic search algorithms; Computer Science; Datavetenskap;

    Sammanfattning : In railways, it is essential to achieve high train punctuality. Thus, whenever disturbances occur, it is important to reschedule the trains effectively. This task is typically handled manually by traffic controllers in real-time. LÄS MER
