  1. 16. Optimization-Based Methods for Revising Train Timetables with Focus on Robustness

    Författare :Fahimeh Khoshniyat; Jan Lundgren; Johanna Törnquist Krasemann; Steven Harrod; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : With increase in the use of railway transport, ensuring robustness in railway timetables has never been this important. In a dense railway timetable even a small disturbance can propagate easily and affect trains' arrival and departure times. In a robust timetable small delays are absorbed and knock-on effects are prevented effectively. LÄS MER

  3. 17. Styrning av tågtrafik på Malmbanan

    Författare :Kristina Nilsson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell logistik; Industrial Logistics;

    Sammanfattning : The single-track Swedish iron ore line Malmbanan stretches from Luleå to the Norwegian city of Narvik. The mine company LKAB transport iron ore on Malmbanan from the mines in Kiruna and Malmberget to the harbours in Narvik and Luleå for export. The daily traffic also consists of passenger trains and freight trains. LÄS MER

  4. 18. Parallel algorithms for real-time railway rescheduling

    Författare :Sai Prashanth Josyula; Johanna Törnquist Krasemann; Lars Lundberg; Mats Brorsson; Blekinge Tekniska Högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In railway traffic systems, it is essential to achieve a high punctuality to satisfy the goals of the involved stakeholders. Thus, whenever disturbances occur, it is important to effectively reschedule trains while considering the perspectives of various stakeholders. LÄS MER

  5. 19. Assessment of Robustness in Railway Traffic Timetables

    Författare :Emma V. Andersson; Jan Lundgren; Anders Peterson; Johanna Törnquist Krasemann; Thorsten Büker; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : A tendency seen for the last decades in many European railway networks is a growing demand for capacity. An increased number of operating trains has led to a delay sensitive system where it is hard to recover from delays, where even relatively small delays are easily propagating to other traffic.

  7. 20. Quality on single-track railway lines with passenger traffic : Anlytical model for evaluation of crossing stations and partial double-tracks

    Författare :Olov Lindfeldt; Bo-Lennart Nelldal; Lars-Göran Mattsson; Nils Olsson; KTH; []
    Nyckelord :Railway operation; Railway capacity; single-track; crossing station; partial double-track; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Railway transportation is showing a substantial increase. Investments in new infrastructure, new fast and comfortable vehicles, and high frequency of service are important factors behind the increase.Infrastructure configuration and timetable construction play important roles in the competitiveness of railway transportation.
