ABSTRACT
Demand Model Classic Mobility Passenger Transport consider, within its structure, the stage of Modal Partition. This step estimates the proportion of travelers using different modes of transport available on a network to make your travels. This study is the estimation of disaggregated models of this stage with mixed data stated preference (PD) and Revealed Preferences (PR) collected in the city of Cagliari, Italy. The alternatives considered are: train, car and bus for PR and train versus car, and train versus bus for DP. The proposed model determines the relative influence of each of the variables in the utility functions, concluding that both the bus and the train mode, comfort and frequency are variables that have a higher weight. In the case of the car, the variable that has greater importance is the number of driver's licenses per household. Individuals perceive the walking time and travel time equally, which is found that the parameters associated with these variables have the same value.
