  4. 2. 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

  5. 3. Analysis of side friction impacts on urban roads : Case study Dar-es-Salaam

    Author : Masatu L. M. Chiguma; Karl-Lennart Bång; Christer Hydén; KTH; []
    Keywords : Side friction factors; urban road links; speed-flow relationships; macroscopic method; microscopic method; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Abstract : Side friction factors are defined as all those actions related to the activities taking place by the sides of the road and sometimes within the road, which interfere with the traffic flow on the travelled way. They include but not limited to pedestrians, bicycles, non-motorised vehicles, parked and stopping vehicles. READ MORE
