Methodological challenges in modelling the choice of mode for a new travel alternative using binary stated choice data - The case of high speed rail in Norway

By critically assessing the practise of translating estimated group scale parameters into nest parameters, we illustrate the inherent limitations of such binary choice data. To overcome some of the problems, we use information from both stated and revealed choice data and propose a model with a cross-nested logit specification, which is estimated on the pooled data set.
