  1. 1. Issues in Urban Travel Demand Modelling : ICT Implications and Trip timing choice

    Författare :Maria Börjesson; Staffan Algers; Kay Axhausen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Journey; Mathematical model; Origin traffic ; Time; Telecommuting; Journey time; Variability; Stated preference; Delay; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur; 11 Road: Personal transport; 11 Road: Personal transport;

    Sammanfattning : Travel demand forecasting is essential for many decisions, such as infrastructure investments and policy measures. Traditionally travel demand modelling has considered trip frequency, mode, destination and route choice. This thesis considers two other choice dimensions, hypothesised to have implications for travel demand forecasting. LÄS MER

  4. 3. Modeling of phase transformations and cyclic plasticity in pearlitic steels

    Författare :Björn Andersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase transformations; TRIP; Pearlitic steel; FEM; Cyclic plasticity; Homogenization;

    Sammanfattning : The low rolling resistance in railway transportation is a key factor for its high efficiency, but it comes at the price of very high contact pressure between the rail and wheel. Due to the high stresses and the large number of load cycles during railway operation, both the rail and the wheel can be susceptible to fatigue crack initiation and propagation. LÄS MER

  5. 4. A Large Eddy Simulation Based Fluid-Structure Interaction Methodology with Application in Hydroelasticity

    Författare :Andreas Feymark; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydroelasticity; subgrid modeling; large eddy simulation; trip model; fluid- structure interaction; numerical simulation; forced oscillation; naval architecture; hydrodynamics;

    Sammanfattning : The phenomenon of hydroelasticity is a subarea of Fluid-Structure Interaction (FSI) and of major importance in many engineering applications related to hydrodynamics and naval architecture e.g. LÄS MER

  7. 5. Analyzing car ownership and route choices using discrete choice models

    Författare :Bijun Han; KTH; []
    Nyckelord :car ownership; accessibility; logit model; route choice; heterogeneity; mixed logit model;

    Sammanfattning : This thesis consists of two parts. The first part analyzesthe accessibility, generation and license holding effects incar ownership models. The second part develops a route choicemodeling framework with an attempt to address the differencesin drivers' route choice behavior. LÄS MER
