1. 36. Steering green buses : The opportunities and challenges of introducing renewable fuel in public transport

   Författare :Malin Aldenius; Miljö- och energisystem; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Public transport; Renewable fuel; Electric buses; Sustainable transport; Green public procurement; Environmental requirements;

   Sammanfattning : The aim of this thesis is to compare and analyse the introduction of renewable fuel in the public transport sector, focusing on the challenges and opportunities encountered by involved stakeholders on the regional and local levels. The results contribute to answering three research questions: 1) How do organisational factors and local and regional contextual factors influence the introduction of renewable fuel? 2) What are the challenges and opportunities of using green public procurement as a policy tool to introduce renewable fuel in the public transport sector? 3) How do the challenges and opportunities regarding the introduction of renewable fuel differ depending on the type of renewable fuel? Four papers are included in the thesis. LÄS MER

3. 37. Three essays on transport CBA uncertainty

   Författare :Peter Almström; Anders Karlström; Svante Berglund; Westin Lars; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cost-Benefit Analysis; Transport planning; Land-use planning;

   Sammanfattning : Cost Benefit Analysis (CBA) has for a long time been used in transport planning, but it is often questioned. One main argument against CBA is that the results depend largely on assumptions regarding one or a few input factors, as for example the future fuel price or valuation of CO2 emissions. LÄS MER

4. 38. Policy Integration for Sustainable Transport Development : Case Studies of Two Swedish Regions

   Författare :Linnea Eriksson; Jenny Palm; Lisa Hansson; Dick Magnusson; Magdalena Fallde; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Policy integration; sustainable transport; region; policy; planning; public administration; institutional logics; organizational identity; boundary object; Sweden; Policy integration; samverkan; hållbara transporter; regional nivå; policy; planering; offentlig förvaltning; institutionella logiker; organisationsidentiteter; gränsobjekt;

   Sammanfattning : It has been argued that for the management of complex issues such as sustainability, which transcend traditional policy sectors and require coordination between several different interests and actors, policymaking depends upon collaboration and integration processes between different sectors and tiers of government. The overall aim of this thesis is therefore to study how and why (or why not) policy integration processes are being developed in regional policymaking and what this means for the achievement of sustainable transport.

5. 39. New Opportunities in Urban Transport Data : Methodologies and Applications

   Författare :Masoud Fadaei Oshyani; Anders Karlström; Oded Cats; Marcus Sundberg; Kari Edison Watkin; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transportvetenskap; Transport Science;

   Sammanfattning : The deployment of Information and Communication Technologies (ICT) is growing in transportation which may contribute to a more efficient and effective service. The data acquired from ICT based systems could be used for many purposes such as statistical analysis and behavior learning and inference. LÄS MER

7. 40. Solute transport in fractured rocks : Analysis of analytical solutions and determination of transport parameters

   Författare :Shuo Meng; Longcheng Liu; Ivars Neretnieks; Lanru Jing; Klaus-Peter Kröhn; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fractured rock; Radionuclide transport; Analytical solution; Dispersion mechanisms; Electromigration.; Sprickigt berg; Radionukidtransport; analytisk lösning; Dispersionsmekanismer; Elektromigration.; Chemical Engineering; Kemiteknik;

   Sammanfattning : In order to facilitate the assessment of the safety and function of deep geological repositories for radioactive waste, several models have been developed to describe water flow and transport of solutes in fractured crystalline rock. The rock around the repository is described and modelled as a network of water-bearing fractures. LÄS MER
