  2. 1. Simulation of rail traffic : applications with timetable construction and delay modelling

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

    Abstract : 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). READ MORE

  4. 2. Simulation of rail traffic : Methods for timetable construction,delay modeling and infrastructure evaluation

    Author : Hans Sipilä; Bo-Lennart Nelldal; Thomas Siefer; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Järnvägsgruppen - Kapacitet; Järnvägsgruppen - Kapacitet; Transportvetenskap; Transport Science;

    Abstract : This thesis covers applications and proposes methods for using simulation in a more effectiveway and also in a wider context than normally used. One of the proposed methods deals withdelay modeling that can be used in a calibration process. READ MORE

  5. 3. RAMS and LCC in rail track maintenance

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

    Abstract : Railway infrastructure is a complex system. An important aspect of the rail infrastructure is that the assets have a long useful life. So once installed, it is very difficult to modify the initial design. Thus, the performance of the infrastructure depends on the maintenance and renewal decisions taken during its life cycle.

  6. 4. Welfare Effects of Transport Policies : an analysis of congestion pricing and infrastructure investments

    Author : Jonas Westin; Lars-Göran Mattsson; Lars Hultkrantz; KTH; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; congestion charge; cost-benefit analysis; tax distortions; transport investment; transport policies; welfare effects; Economics; Nationalekonomi; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur; SRA - Transport; SRA - Transport;

    Abstract : Interactions between the transport market and other distorted markets, such as the labor market, can have a large impact on the overall welfare effect of a road pricing policy or a congestion charge. Many road pricing studies therefore try to incorporate effects from other distorted markets in the analysis. READ MORE

  7. 5. On Energy Efficient Mobile Hydraulic Systems : with Focus on Linear Actuation

    Author : Kim Heybroek; Petter Krus; Jan-Ove Palmberg; Torben Ole Andersen; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In this dissertation, energy efficient hydraulic systems are studied. The research focuses on solutions for linear actuators in mobile applications, with emphasis on construction machines. Alongside the aspect of energy efficiency, the thesis deals with competing aspects in hydraulic system design found in the development of construction machines. READ MORE
