  1. 11. On Ground and Structural Vibrations Related to Railway Traffic

    Författare :Johan O. Jonsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wave propagation; wave field excitation; soil structure interaction; structural vibration; ground vibration; traffic vibration;

    Sammanfattning : The continuous development and integration of railway infrastructure, especially within urban areas, can cause ground and building vibrations to reach levels that bring discomfort to people. The growing risk of damage to buildings located in areas prone to ground vibration should not be underestimated. LÄS MER

  3. 12. Towards an efficient use of infrastructure and the built environment : Essays in transport and housing economics

    Författare :Lina Jonsson; Fastighetsvetenskap; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Hedonic pricing; Noise; Railway traffic; Road traffic; Congestion pricing; Acceptability; Road user charging; Political Economy; Railway; Marginal cost; Accident probability; Level crossings; Housing Economics; Property tax;

    Sammanfattning : All four papers in the thesis share a common theme: how to achieve an efficient use of infrastructure and the built environment. In the presence of externalities, pricing according to the (short-run) marginal cost is one answer on how this can be achieved and the first two papers estimates parts of the marginal cost of traffic.

  4. 13. Evaluation of passenger train concepts : Methods and results of measuring travellers' preferences in relation to cost

    Författare :Karl Kottenhoff; KTH; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Politicians would like the railways to help to solve futuretransport and environmental problems. People can travel to andfrom work and on business during the day on modern trains whichare faster than any other alternative on journeys ofintermediate length. LÄS MER

  5. 14. Delays and Timetabling for Passenger Trains

    Författare :Carl-William Palmqvist; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rail; delay; timetable; train; punctuality; Rail transportation;

    Sammanfattning : Travel by train has increased steadily in Sweden the last 30 years. The pace has been about two to three percent per year, and we now have twice as many passengers. With growing awareness of the changing climate, the pace is increasing further. A problem that affects both passengers and businesses in Sweden is train delays. LÄS MER

  7. 15. Vibrations from Railway Traffic : Computational Modeling and Analysis

    Författare :Jens Malmborg; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Train-induced vibrations; ground vibration; wave propagation; soil dynamics; finite element method; soil stiffening; critical velocity;

    Sammanfattning : The population is growing, and an increasing proportion of the population lives in urban areas. As a consequence, human exposure to noise and vibrations is increasing; two major sources being railway and road traffic. Larger and denser cities lead to a higher amount of traffic close to where people work and live. LÄS MER
