1. 1. 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

3. 2. 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

4. 3. Railway operation analysis : Evaluation of quality, infrastructure and timetable on single and double-track lines with analytical models and simulation

   Författare :Olov Lindfeldt; Bo-Lennart Nelldal; Lars-Göran Mattsson; Ingo Hansen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway operation; Railway capacity; Single-track; Double-track; Partial double-track; Inter-station distance; Delay; Delay propagation; Crossing; Overtaking; Timetable flexibility; Simulation; Experimental design; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

   Sammanfattning : This thesis shows the advantages of simple models for analysis of railway operation. It presents two tools for infrastructure and timetable planning. It shows how the infrastructure can be analysed through fictive line designs, how the timetable can be treated as a variable and how delays can be used as performance measures. LÄS MER

5. 4. Simulation of rail traffic : applications with timetable construction and delay modelling

   Författare :Hans Sipilä; Bo-Lennart Nelldal; Anders Holst; Jan Ekman; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : This thesis covers both applications where simulation is used on parts of the Swedish rail networks and running time calculations for future high-speed trains with top speed improvements on existing lines. Calculations are part of a subproject within the Green Train research program (Gröna tåget). LÄS MER

7. 5. Congested railways : influence of infrastructure and timetable properties on delay propagation

   Författare :Anders Lindfeldt; Bo-Lennart Nelldal; Markus Bohlin; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : In this thesis the symptoms and underlying behaviour of congestion on railways are analysed and discussed. As well as in many other countries, Sweden faces increasing demand for transport. To meet this new demand, railways play an important role. LÄS MER
