2. 6. Modelling and Appraisal in Congested Transport Networks

   Author : Jens West; Maria Börjesson; Oded Cats; Leonid Engelsson; Giulio Cantarella; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transport modelling; Transit Assignment; Appraisal; Congestion; Crowding; Cost-benefit analysis; Value of time; Congestion charge; Dynamic traffic assignment; Transportvetenskap; Transport Science;

   Abstract : Appraisal methodologies for congestion mitigation projects are relatively less well developed compared to methodologies for projects reducing free flow travel times. For instance, static assignment models are incapable of representing the build-up and dissipation of traffic queues, or capturing the experienced crowding caused by uneven on-board passenger loads.

4. 7. Dynamic modeling of Internet congestion control

   Author : Krister Jacobsson; Håkan Hjalmarsson; Douglas Leith; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Congestion control; TCP; Control theory; Fluid flow modeling; Internet; Telecommunication; Telecommunication; Telekommunikation;

   Abstract : The Transmission Control Protocol (TCP) has successfully governed the Internet congestion control for two decades. It is by now, however, widely recognized that TCP has started to reach its limits and that new congestion control protocols are needed in the near future. READ MORE

5. 8. Control of vehicle platoons and traffic dynamics : catch-up coordination and congestion dissipation

   Author : Mladen Čičić; Karl H. Johansson; Daniel Work; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic Congestion; Intelligent Transport Systems; Moving Bottlenecks; Platoon Coordination; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Traffic congestion is a constantly growing problem, with a wide array ofnegative effects on the society, from wasted time and productivity to elevated air pollution and increased number of accidents. Classical traffic control methods have long been successfully employed to alleviate congestion, improving the traffic situation of many cities and highways. READ MORE

6. 9. Designing Urban Road Congestion Charging Systems : Models and Heuristic Solution Approaches

   Author : Joakim Ekström; Jan Lundgren; Anders Karlström; Linköpings universitet; []
   Keywords : transport modeling; congestion pricing; network design; bi-level optimization; toll locations; traffic assignment; user equilibrium; collection cost; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : The question of how to design a congestion pricing scheme is difficult to answer and involves a number of complex decisions. This thesis is devoted to the quantitative parts of designing a congestion pricing scheme with link tolls in an urban car traffic network. READ MORE

7. 10. Welfare Effects of Transport Policies : an analysis of congestion pricing and infrastructure investments

   Author : Jonas Westin; Lars-Göran Mattsson; Lars Hultkrantz; KTH; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; congestion charge; cost-benefit analysis; tax distortions; transport investment; transport policies; welfare effects; Economics; Nationalekonomi; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur; SRA - Transport; SRA - Transport;

   Abstract : Interactions between the transport market and other distorted markets, such as the labor market, can have a large impact on the overall welfare effect of a road pricing policy or a congestion charge. Many road pricing studies therefore try to incorporate effects from other distorted markets in the analysis. READ MORE
