    Författare :Anders Peterson; Jan Lundgren; Torbjörn Larsson; Lars-Göran Mattsson; Linköpings universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 2. Five papers on large scale dynamic discrete choice models of transportation

    Författare :Oskar Blom Västberg; Anders Karlström; R. Daniel Jonsson; Marcus Sundberg; Karin Brundell-Freij; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transportvetenskap; Transport Science;

    Sammanfattning : Travel demand models have long been used as tools by decision makers and researchers to analyse the effects of policies and infrastructure investments. The purpose of this thesis is to develop a travel demand model which is: sensitive to policies affecting timing of trips and time-space constraints; is consistent with microeconomics; and consistently treats the joint choice of the number of trips to perform during day as well as departure time, destination and mode for all trips.

  4. 3. Improvement of departure time suitability for interregional rail timetables

    Författare :Félix Vautard; Oskar Fröidh; Chengxi Liu; Camilla Byström; Henrik Andersson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Transportsystem; Transport Systems;

    Sammanfattning : In order to respond to growing interregional rail traffic, rail capacity should be allocated better. To achieve this, one possibility is to optimise suitability of departure times for rail passengers in the timetabling process. LÄS MER

  5. 4. Transport, Mobility, and Workplace Location : Models and Applications

    Författare :Fatemeh Naqavi; Muriel Beser Hugosson; Nathalie Picard; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transportsystem; Transport Systems;

    Sammanfattning : Travel demand analysis is one of the core constituents of transportation studies. Therequired insight to maintain and develop a sustainable transportation system, in additionto learning from previous research globally and locally, is generated from studyingthe effects of previous policies, investigating future possibilities and potential outcomes,and describing the current situation.
