  1. 1. Estimering av efterfrågan på långväga persontransporter : En ekonomisk-teoretisk belysning av gängse modeller samt en ny ansats till uppskattning av efterfrågesamband

    Sammanfattning : This dissertation deals with the estimation of intercity travel demand. The purpose is to discuss the derivations and characteristics of existing models, to derive a demand model based on microeconomic theory and to estimate the parameters of the model in order to gain information on important characteristics of the transport system.

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

    Författare :Maria Börjesson; Staffan Algers; Kay Axhausen; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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; Travel Demand; ICT; Tele-substitution; Revealed Preference; Stated Preference; Mixed Logit; Unobserved Heterogeneity; Travel Time Uncertainty; Schedule Delay;

    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. 4. Communication technology and travel demand models

    Författare :Maria Börjesson; Infrastruktur KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Travel survey; Transport mode; Telecommuting; Mathematical model; Motivation; 11 Road: Personal transport; 11 Road: Personal transport;

    Sammanfattning : Transportation planners have traditionally focused on physical travel only, and disregarded the fact that other modes of communication may influence travel demand. However, modern telecommunications are rapidly increasing the accessibility to activities that previously only could be reached by physical transportation. LÄS MER

  5. 5. Studies in Local Public Transport Demand

    Författare :Johan Holmgren; Jan Owen Jansson; Lars Westin; Linköpings universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Public transport; Demand; Elasticity; Price; Service; Time series; Panel data; Kollektivtrafik; Efterfrågan; Elasticitet; Pris; Trafikutbud; Inkomst; Bilinnehav; Tidsserieanalys; Paneldata; Economics; Nationalekonomi;

    Sammanfattning : This thesis consists of four papers where the overall purpose is to contribute to the understanding of how local public transport demand is affected by different factors. An underlying theme running trough the thesis is the two-way relationship between public transport demand and the service level caused by the fact that capacity and quality are joint products. LÄS MER
