English Before implementing a model of mode choice in urban travel, one needs to solve several problems relating to the framing of the analysis. The present study argues that loglinear models may be usefully applied to the analysis of categorical variables. Two problems are considered. Firstly, the methods proposed by loglinear models for identifying the interrelationships existing between a set of variables are exploited in order to evaluate the possibilities of reducing the dimensions of the table of reference. The case under examination relates to the possible extension of results obtained at national level as estimates of the characteristics of individualregions. The alternative choices open to the user differ according to several circumstances, the length of the journey being among the most important. In the second part of the study choice sets are defined to narrow down the analysis of the essential alternatives, without however sacrificing the representativity of the results.
