TRANSFERABILITY OF DISAGGREGATE TRIP GENERATION MODELS

This paper investigates the transferability of travel demand models describing the frequency of travel undertaken by members of a household. Travel activity is represented in terms of the number of tours and number of non-home stops made by members of a household instead of the conventional representation in terms of the number of trips. Two disaggregate data bases, collected in Minneapolis and Baltimore, are used to empirically investigate intra-and inter-regional transferability of tours-and stops-generation models. A set of measures is used to evaluate the effectiveness of model transfer. The high variability in transfer effectiveness obtained from the empirical analyses suggests that model transfer should be employed with care to assure that the transferred model is useful in the application context. The results indicate that adjustment of the transfer model, by updating the intercept constant of the regression model using data from the application context, produces an important increase in transfer effectiveness.
