  1. 1. Simulation Studies for Improved Efficiency in Road and Rail Freight Transports

    Author : Ingrid Johansson; Markus Bohlin; Oskar Fröidh; Behzad Kordnejad; Carl-William Palmqvist; C. Tyler Dick; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heavy-duty vehicle platooning; road traffic simulation; intelligent transport systems; optimal control; longitudinal cruise control; fuel economy; railway traffic simulation; microscopic simulation; macroscopic simulation; freight trains; early departures; capacity; railway stations; strategic planning; timetable compression; UIC Code 406; Transportsystem; Transport Systems;

    Abstract : The demand for road and rail freight transport continues to grow with the expanding economy, while the climate crisis requires reduction in greenhouse gas emissions. Therefore, tools and solutions for reducing fossil fuel use and enabling more efficient use of infrastructure are needed. READ MORE

  2. 2. Efficiency of the trackwork scheduling process in Sweden

    Author : Daria Ivina; Trafik och väg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railways; Maintenance management; Trackwork scheduling; Project Uncertainties; Lean; Efficiency;

    Abstract : Efficient scheduling is vital for railway maintenance, which is increasingly challenged by rising train traffic and infrastructure wear. Trackwork often necessitates the reduction of train speeds and the partial or complete closure of tracks. READ MORE

  3. 3. A System-of-Systems Approach for Enhancing Asset Management of Railway System

    Author : Jaya Kumari; Ramin Karim; Adithya Thaduri; Pierre Dersin; Miguel Castaño Arranz; Mirka Kans; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; railways rolling stock; system-of-systems; asset management; maintenance; fleet management; industrial AI; digitalisation; Operation and Maintenance Engineering; Drift och underhållsteknik;

    Abstract : In Sweden, railway transport of freight and passengers is a significant portion of the total transport system. The demand for railway transport is forecasted to increase in the coming decades. One of the main reasons for this ever-increasing demand is the requirement for sustainable transport, nationally and globally. READ MORE

  4. 4. Railway capacity analysis : Methods for simulation and evaluation of timetables, delays and infrastructure

    Author : Anders Lindfeldt; Bo-Lennart Nelldal; Ullrich Martin; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Järnvägsgruppen - Kapacitet; Järnvägsgruppen - Kapacitet;

    Abstract : 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 transportation. To meet this new demand, railways play an important role. READ MORE
