Problems arising in the Logit approach : an example from the transportation economy,
by Pascal Bouyaux.
This article presents a survey of the traditional foundations and interpretations of a Logit approach, applied to the urban travel demand modelling. Using the notion of stochastic rationality introduced by Falmagne (1978), it formalises the theoretical framework from which McFadden (1974) derived the Logit model with the maximisation of a random utility function. This framework, corresponding solely to the modelling of preferences heterogeneousness of a population, is too limited because it doesn't take into account the non-repeated character of the travellers choice's process. Therefore, an alternative model is proposed, originally elaborated by Beggs, Cardell and Hausman (1981) : the ordered Logit model. Beyond the preferences' heterogeneousness, this new approach allows to give back to the urban travel demand modelling all his behavioral character. Source : Éditeur (via Persée) |
