  2. 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

  4. 2. Evaluating and Improving the Transport Efficiency of Logistics Operations

    Author : Jiali Fu; Harilaos Koutsopoulos; Constantinos Antoniou; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transport efficiency; earthmoving operations; off-peak urban deliveries; simulation; optimization; GPS data; Transportvetenskap; Transport Science;

    Abstract : The thesis focuses on evaluating and improving the transport efficiency of two types of logistics operations in the supply chain.One research area is the production of raw material in construction operations, specifically earthmoving operations. READ MORE

  5. 3. A Simulation-Optimization Approach for Improved Robustness of Railway Timetables

    Author : Johan Högdahl; Markus Bohlin; Oskar Fröidh; Alireza Ahmadi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railroad; Timetabling; Optimization; Simulation; Robustness; Punctuality; Delay prediction.; Järnväg; Tidtabelläggning; Optimering; Simulering; Robusthet; Punktlighet; Förseningsprediktion.; Transportvetenskap; Transport Science; Transportsystem; Transport Systems;

    Abstract : The timetable is an essential part for the operations of railway traffic, and its quality is considered to have large impact on capacity utilization and reliability of the transport mode. The process of generating a timetable is most often a manual task with limited computer aid, and is known to be a complex planning problem due to inter-train dependencies. READ MORE

  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. Application of Predictive Analytics for Shunting Yard Delays

    Author : Niloofar Minbashi; Markus Bohlin; Behzad Kordnejad; Carl-William Palmqvist; Paola Pellegrini; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shunting yards; train delays; machine learning; simulation; freight transport; Godsbangårdar; tåg förseningar; maskininlärning; simulering; godstransport; Transportsystem; Transport Systems;

    Abstract : Increasing the modal share of rail freight transport is one of the main ways to achieve carbon neutrality in Europe. The perceived low reliability and predictability of rail freight services is one of the main challenges to overcome in reaching this target. READ MORE
