  1. 1. Competition in Public Transport : Essays on competitive tendering and open-access competition in Sweden

    Författare :Andreas Vigren; Svante Mandell; Jan-Eric Nilsson; Nash Nash; Statens väg- och transportforskningsinstitut; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Public transport; Contract; Tender; Bus; Economic efficiency; Competition; Location; Transport operator; Depot transp ; Impact study; Railway; Line transp ; 02 Road: Economics; 02 Road: Economics; 111 Road: Public transport; 111 Road: Public transport; J13 Railway: Economics; J13 Railway: Economics; Transportvetenskap;

    Sammanfattning : The results of this work show that the cost efficiency of tendered bus services is similar across all Swedish counties, except for the more high-density counties where efficiency is lower. Considerably lower efficiency is also found for contracts with services run in-house by the Public Transport Authority (PTA), compared to when the same service is run by a private actor. LÄS MER

  3. 2. Costs in Swedish Public Transport : An analysis of cost drivers and cost efficiency in public transport contracts

    Författare :Andreas Vigren; Svante Mandell; Johan Holmgren; Statens väg- och transportforskningsinstitut; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cost; Increase; Efficiency; Contract; Procurement; Public transport; 02 Road: Economics; 02 Road: Economics; Transportvetenskap;

    Sammanfattning : During the last seven years, the total cost for Swedish public transport provision has increased by over 30 percent in real terms according to figures from the government agency Transport Analysis. A similar pattern is found if considering a longer time span. LÄS MER

  4. 3. Modelling and measuring transport in fusion plasmas

    Författare :Istvan Pusztai; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fusion plasmas; ITG stability; microinstabilities; de-convolution; Lorentz operator; gyrokinetic equation; transport; quasilinear flux; beam emission spectroscopy; ion temperature gradient mode; electron density measurement; trapped electron response;

    Sammanfattning : In the present thesis we consider theoretical and experimental aspects of the turbulent transport which is a crucial issue in fusion plasma physics.Experimental observations and gyrokinetic simulations show that collisions strongly influence the turbulent flux of particles.
