  2. 1. The Origin-Destination Matrix Estimation Problem : Analysis and Computations

    Author : Anders Peterson; Jan Lundgren; Torbjörn Larsson; Lars-Göran Mattsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Traffic modelling; Travel demand; Origin--Destination matrix; Traffic flow observation; Detector allocation; Estimation.; OD-matris; Trafikflödesobservation; Detektorallokering; Skattning; Trafikmodellering; Reseefterfrågan; Optimization; systems theory; Optimeringslära; systemteori;

    Abstract : For most kind of analyses in the field of traffic planning, there is a need for origin--destination (OD) matrices, which specify the travel demands between the origin and destination nodes in the network. This thesis concerns the OD-matrix estimation problem, that is, the calculation of OD-matrices using observed link flows. READ MORE

  4. 2. Origin-destination matrix estimation from traffic counts

    Author : Anders Peterson; Henrik Edwards; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : For most kind of analyses in the field of traffic modeling, there is a need for origin-destination (OD) matrices, which specify the travel demands between the origin and destination nodes in the network. The process of obtaining OD-matrices is long, complicated and expensive. READ MORE

  5. 3. Simulation of rail traffic : applications with timetable construction and delay modelling

    Author : Hans Sipilä; Bo-Lennart Nelldal; Anders Holst; Jan Ekman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis covers both applications where simulation is used on parts of the Swedish rail networks and running time calculations for future high-speed trains with top speed improvements on existing lines. Calculations are part of a subproject within the Green Train research program (Gröna tåget). READ MORE

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

    Author : Maria Börjesson; Staffan Algers; Kay Axhausen; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE

  7. 5. The GMOC Model : Supporting Development of Systems for Human Control

    Author : Simon Tschirner; Bengt Sandblad; Anders Jansson; Sebastiaan Meijer; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Human-Computer Interaction; User-Centered Design; Human Control; Train Traffic Control; Usability; System Development; Human Work; Railway Traffic; Rail Human Factors; Mental Models; Situation Awareness; Datavetenskap med inriktning mot människa-datorinteraktion; Computer Science with specialization in Human-Computer Interaction;

    Abstract : Train traffic control is a complex task in a dynamic environment. Different actors have to cooperate to meet strong requirements regarding safety, punctuality, capacity utilization, energy consumption, and more. The GMOC model has been developed and utilized in a number of studies in several different areas. READ MORE
