  4. 4. Issues in Estimation and Application of Long Distance Travel Demand Models

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Muriel Beser Hugosson; [2003]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Intercity travel; logit model; market segments; stated preference; bootstrap; heteroscedastic extreme value model; nested logit;

    Sammanfattning : Forecasts of the demand for long distance travel areessential for many decisions, such as infrastructureinvestments, operators´management policies etc. Manyresearch issues are related to this field, and the purpose ofthis thesis is to contribute to some of them. LÄS MER

  5. 5. Communication technology and travel demand models

    Detta är en avhandling från Stockholm : Infrastruktur

    Författare :Maria Börjesson; [2003]
    Nyckelord :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
