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

   Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

   Författare :Andreas Vigren; KTH.; Statens väg- och transportforskningsinstitut.; [2017]
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Transportvetenskap; Transport Science; Competition; Public Transport; Tendering; Procurement; Cost efficient; Bus; Railway; Open access competition; 02 Road: Economics; 02 Road: Economics; 111 Road: Public transport; 111 Road: Public transport; J13 Railway: Economics; J13 Railway: Economics; Public transport; Contract; Tender; Economic efficiency; Location; Transport operator; Depot transp ; Impact study; Line transp ;

   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. Making Equity in Public Transport Count

   Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

   Författare :Isak Rubensson; KTH.; [2019]
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Public transport; Subsidies; Fare-schemes; Accessibility; Crowding; transport justice; Equity; Distribution; Gini index; Lorenz curves; Customer satisfaction; Service quality; Preferences; Reliability; Transportsystem; Transport Systems; Transportvetenskap; Transport Science;

   Sammanfattning : Political and public focus on equity and justice outcomes of public policies is on the rise all over the world. Equity is both philosophically motivated and often decreed by law and in planning directives to be monitored when policies are changed, however oftentimes these equity assessments are vague, qualitative and carries low weight in policy decision processes.

4. 3. Efficiency and acceptability of pricing policies and transport investments in distorted economies

   Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

   Författare :Jonas Westin; KTH.; [2012]
   Nyckelord :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;

   Sammanfattning : 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.

7. 5. Collisional transport in edge transport barriers and stellarators

   Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

   Författare :Stefan Buller; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; plasma physics; pedestal; collisional transport; fusion; stellarator; tokamak; transport; impurity transport;

   Sammanfattning : Nuclear fusion has the potential to generate abundant and clean energy. In magnetic confinement fusion, the temperatures needed to achieve fusion are obtained by confining a hot plasma with magnetic fields. LÄS MER
