  1. 1. Congestion Charging in Urban Networks : Modelling Issues and Simulated Effects

    Författare :Ida Kristoffersson; Leonid Engelson; Otto Anker Nielsen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transport Modelling; Congestion Charging; Departure Time Choice; Dynamic Traffic Simulation; Welfare Effects; Equity;

    Sammanfattning : One of the major challenges cities face today, in their development towards sustainable urban areas, is the need for an efficient and environmentally friendly transport system. This transport system should manage to tie together the city without strong adverse impact on urban environment, air-quality and climate change. LÄS MER

  3. 2. Designing Urban Road Congestion Charging Systems : Models and Heuristic Solution Approaches

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

    Sammanfattning : 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. LÄS MER

  4. 3. Stockholmarnas resvanor – mellan trängselskatt och klimatdebatt

    Författare :Greger Henriksson; Avdelningen för etnologi; []
    Nyckelord :HUMANIORA; HUMANITIES; climate change; Travel habits; Stockholm county; traffic policy; environmental aspects; city of Stockholm; interdisciplinary research; congestion charging; the Stockholm trial; policy instruments; habits; mobility; urban transport; actor network theory;

    Sammanfattning : This thesis examines the concept of travel habits, public responses to large-scale traffic congestion regulations and how travel patterns of urban dwellers can be made environmentally sustainable in the long term. It also examines the interrelationships of different scientific disciplines dealing with urban travel. LÄS MER

  5. 4. Modelling and Appraisal in Congested Transport Networks

    Författare :Jens West; Maria Börjesson; Oded Cats; Leonid Engelsson; Giulio Cantarella; KTH; []
    Nyckelord :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;

    Sammanfattning : 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.

  7. 5. Aspects of Static Multi-Class Traffic equilibria under Congestion Pricing

    Författare :Per Olov Lindberg; Lars-Göran Mattsson; David Watling; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; traffic; congestion pricing; equilibria; marginal social cost; Other civil engineering and architecture; Övrig samhällsbyggnadsteknik och arkitektur;

    Sammanfattning : Congestion charging is a now accepted means of influencing traffic to behave in a more socio-economic optimal way, like e.g. in the Stockholm project. Already early work, in the 1920’s, showed that road use can be inefficient due externalities, i. LÄS MER
