    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Self-driving vehicles; Public transport; Four-step transport model; Societal impacts; Sampers; Machine Design; Maskinkonstruktion;

    Abstract : During the last decade, self-driving technology has become increasingly visible in the news, with the vision that people would enter vehicles that drive themselves, and that people could instead rest, read the newspaper, or have a meeting. However, these visions have mainly focused on the potential for car usage, even though public transport could benefit greatly from self-driving technology. READ MORE

  5. 18. Efficiency and acceptability of pricing policies and transport investments in distorted economies

    Author : Jonas Westin; Lars-Göran Mattsson; Jonas Eliasson; Joel Franklin; Kurt Van Dender; KTH; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; road pricing; transport investment; cost-benefit analysis; tax distortions; transport policies; welfare effects; political economy; acceptability; SRA - Transport; SRA - Transport;

    Abstract : This thesis contains five papers studying the economic efficiency and political acceptability of road pricing policies and transport investments in distorted economies. Interactions between the transport market and other distorted markets, such as the labor market, can have a large impact on the welfare effect of a road pricing policy or a transport investment.

    Abstract : The railway is an important mode of transport, due to its environmental friendliness, high safety level, and low energy consumption, among other reasons. Railways provide a sustainable means of transporting a large amount of freight and passengers, in a cost-effective and comfortable way. READ MORE

  7. 20. 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.
