  5. 4. Modelling demand for high speed rail in Sweden. : Business trips

    Master-uppsats, KTH/Transportvetenskap

    Författare :Sida Jiang; [2011]
    Nyckelord :;

    Sammanfattning : Recently conducted revealed preference and stated choice surveys in Sweden have extended data availability for travel demand modelling. Refined models with destination and mode choice are herein developed mainly for the long-distance business-trip market in Sweden. LÄS MER

  7. 5. Travel demand forecasting with stated choice data. : Swedish domestic long-distance trips.

    Master-uppsats, KTH/Transportvetenskap

    Författare :Qian Wang; [2011]
    Nyckelord :;

    Sammanfattning : The travel demand forecasting capability is affected by the model performance and is restricted by the available modes. The Sampers models being used in long distance travel demand forecasting doesn’t deal with nonlinearity and contains no travel service qualitative variables. LÄS MER
