1. 26. Five papers on large scale dynamic discrete choice models of transportation

   Författare :Oskar Blom Västberg; Anders Karlström; R. Daniel Jonsson; Marcus Sundberg; Karin Brundell-Freij; KTH; []

   Sammanfattning : Travel demand models have long been used as tools by decision makers and researchers to analyse the effects of policies and infrastructure investments. The purpose of this thesis is to develop a travel demand model which is: sensitive to policies affecting timing of trips and time-space constraints; is consistent with microeconomics; and consistently treats the joint choice of the number of trips to perform during day as well as departure time, destination and mode for all trips.

3. 27. Transport system optimization and pricing

   Författare :Jan Owen Jansson; Handelshögskolan i Stockholm; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Sammanfattning : How should the pricing principles prescribed by welfare economic theory be translated into operational pricing policy for different transport services? This question is considered for scheduled transport services in general, and for urban bus transport and cargo shipping in particular, for seaports and for highways. The second main question is: what would the financial result be in these cases of applying a pricing policy aimed at net social benefit mazimization? To answer this second question the tempting short-cut of assuming the whole supply-side as given, which is typical of the prevailing price theory, has to be resisted. LÄS MER

4. 28. Towards electrified public bus transport : The case of Stockholm

   Författare :Maria Xylia; Semida Silveira; Maria Börjesson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electric bus; charging infrastructure; optimisation; public transport; fossil-free; transport planning; Sweden; Energy Technology; Energiteknik;

   Sammanfattning : This thesis addresses the challenge of road transport electrification using a systems approach for the particular context of Stockholm’s public transport system. The objective is to identify the benefits of large-scale bus electrification on energy efficiency and greenhouse gas emissions, as well as the cost and planning considerations required for achieving such a shift.

5. 29. Hepatic Disposition of Drugs and the Utility of Mechanistic Modelling and Simulation

   Författare :Erik Sjögren; Hans Lennernäs; Scott Obach; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hepatic disposition; pharmacokinetics; mechanistic modelling; drug-drug interactions; enzyme kinetics; Vmax; Km; CLint; carrier-mediated transport; active transport; modelling; in vitro-in vivo extrapolation; physiologically based pharmacokinetic model; optimal experimental design; experimental optimization; data analysis optimization; PHARMACY; FARMACI; Biopharmacy; Biofarmaci; Biopharmaceutics; Biofarmaci;

   Sammanfattning : The elimination of drugs from the body is in many cases performed by the liver. Much could be gained if an accurate prediction of this process could be made early in the development of new drugs. However, for the elimination to occur, the drug molecule needs first to get inside the liver cell. LÄS MER

7. 30. Coordination of Heavy-Duty Vehicle Platooning

   Författare :Sebastian van de Hoef; Dimos V. Dimarogonas; Simona Sacone; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; road freight transport; optimization; optimal control; automatic control; fuel-efficiency; match-making; off-board; intelligent transport systems; automated driving; clustering; scheduling; cooperative; large-scale; dynamic programming; trucks; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : A network-wide coordination system for heavy-duty vehicle platooning with the purpose of reducing fuel consumption is developed. Road freight is by far the dominating mode for overland transport with over 60 % modal share in the OECD countries and is thus critically important for the economy.
