1. 11. Highway Traffic State Estimation and Short-term Prediction

   Författare :Andreas Allström; Jan Lundgren; Clas Rydergren; Balázs Adam Kulcsár; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Sammanfattning : Traffic congestion is increasing in almost all large cities, leading to a number of negative effects such as pollution and delays. However, building new roads is not a feasible solution. Instead, the use of the existing road network has to be optimized, together with a shift towards more sustainable transport modes. LÄS MER

3. 12. Exploring societal impacts of self-driving public transport using four-step transport models

   Författare :Erik Almlöf; Mikael Nybacka; Erik Jenelius; Mia Hesselgren; Clas Rydergren; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Self-driving vehicles; Public transport; Four-step transport model; Societal impacts; Sampers; Machine Design; Maskinkonstruktion;

   Sammanfattning : 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. LÄS MER

4. 13. 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

5. 14. Mode choice modelling of long-distance passenger transport based on mobile phone network data

   Författare :Angelica Andersson; Maria Börjesson; Ida Kristoffersson; Clas Rydergren; Leonid Engelson; Jonas Westin; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Demand model; Mode choice; Latent class; Mobile phone network data; Travel behaviour; Long-distance travel;

   Sammanfattning : Reliable forecasting models are needed to achieve the climate related goals in the face of increasing transport demand. Such models can predict the long-term behavioural response to policy interventions, including infrastructure investments, and thus provide valuable pre-dictions for decision makers. LÄS MER

7. 15. Third Party Logistics : Outsourcing Logistics in Partnerships

   Författare :Dan Andersson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Logistics; Third-Party Logistics; Contract Logistics; Outsourcing; Partnerships; Operational Alliances; Physical Distribution; Materials Management;

   Sammanfattning : The purpose of this dissertation is to contribute the body of knowledge of the outsourcing of logistics services in integrated relationships between a shipper ( e.g. a manufacturer) and a logistics service provider (e.g. LÄS MER
