Abstract

In this paper, the transferability of person-based standardized regression models is analysed using two large-scale origin-destination household surveys with data collected in two Brazilian cities, Sa˜o Paulo and Bauru. The models are specified in terms of dummy variables linked to socio-economic attributes which are considered relevant. A model, having home-based daily trips as a dependent variable, is calibrated according to data from the Sa˜o Paulo Metropolitan Area and transferred to Bauru, and vice-versa. The transferability of the models is evaluated using the Wald test, which is an objective test applicable to two samples presenting different variances. According to the test, only standardized regression models are transferable. In addition, the performance of the models to estimate the number of trips generated in every zone of the urban areas is verified. The results indicate that the performance of standardized regression models is equivalent to the locally calibrated model.
