  1. 16. Challenges for ERTMS related to implementation, technology and railway capacity

    Författare :Vahid Ranjbar; Oskar Fröidh; Nils Olsson; Olov Lindfeldt; Johan Silfwerbrand; Anders Peterson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transportsystem; Transport Systems;

    Sammanfattning : The main purpose of European Rail Traffic Management System (ERTMS) is to remove crossborder barriers and create an interoperable railway network across European countries (Smithet al. 2012). Since its birth, ERTMS has faced several issues regarding interoperability andimplementation. LÄS MER

  3. 17. Evaluation of Train Driving with Lineside ATPand ERTMS Signaling

    Författare :Tomas Rosberg; Markus Bohlin; Birgitta Thorslund; Behzad Kordnejad; Ziemke Tom; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transportsystem; Transport Systems;

    Sammanfattning : From many perspectives there is a need to understand more of how capacity, signal systems, anddriving behavior interact, and naturally since ERTMS is in its early stage, some areas are stillunexplored. The number of retrofitted ERTMS lines and new designed ERTMS lines are increasing inEurope, which implies extra focus on the capacity optimization in the network planning process. LÄS MER

  4. 18. Going from Lineside to In-cab Railway Signaling : Driveability Issues and Solutions

    Författare :Tomas Rosberg; Oskar Fröidh; Thorslund Birgitta; Behzad Kordnejad; Birgit Milius; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ERTMS; ETCS; Driving behavior; signaling; Transportsystem; Transport Systems;

  5. 19. Improvement of departure time suitability for interregional rail timetables

    Författare :Félix Vautard; Oskar Fröidh; Chengxi Liu; Camilla Byström; Henrik Andersson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Transportsystem; Transport Systems;

    Sammanfattning : In order to respond to growing interregional rail traffic, rail capacity should be allocated better. To achieve this, one possibility is to optimise suitability of departure times for rail passengers in the timetabling process. LÄS MER

  7. 20. 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
