  2. 1. Aspects of improving punctuality : from data to decision in railway maintenance

    Author : Birre Nyström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Abstract : The increasing demand for transportation and sustainability makes railways attractive. The ongoing deregulation of state-owned railways means that many new organisations are entering the railway sector. READ MORE

  4. 2. A Simulation-Optimization Approach for Improved Robustness of Railway Timetables

    Author : Johan Högdahl; Markus Bohlin; Oskar Fröidh; Alireza Ahmadi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railroad; Timetabling; Optimization; Simulation; Robustness; Punctuality; Delay prediction.; Järnväg; Tidtabelläggning; Optimering; Simulering; Robusthet; Punktlighet; Förseningsprediktion.; Transportvetenskap; Transport Science; Transportsystem; Transport Systems;

    Abstract : The timetable is an essential part for the operations of railway traffic, and its quality is considered to have large impact on capacity utilization and reliability of the transport mode. The process of generating a timetable is most often a manual task with limited computer aid, and is known to be a complex planning problem due to inter-train dependencies. READ MORE

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

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

    Abstract : 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. READ MORE

  6. 4. Management of condition information from railway punctuality perspectives

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

    Abstract : 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.

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

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

    Abstract : 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. READ MORE
