  1. 1. 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

  3. 2. Optimization Approaches for Design of Congestion Pricing Schemes

    Författare :Joakim Ekström; Jan Lundgren; Richard Connors; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In recent years, there has been a growing interest in congestion pricing as a tool for solving traffic congestion problems in urban areas. However, the transportation system is complex and to design a congestion pricing scheme, i.e. to decide where and how much to charge the road users, is not trivial. LÄS MER

  4. 3. Features of adult neural progenitor cells

    Författare :Lisa Arvidsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :adult neural progenitor cell;

    Sammanfattning : The adult Central Nervous System (CNS) harbors neural progenitor cells (NPCs) in three areas: the subventricular zone (SVZ) of the lateral ventricles and the subgranular zone in the hippocampus and around the central canal in the spinal cord. The NPCs can be isolated and cultured in vitro. LÄS MER
