Modeling Heterogeneity in Trip-distributions with Partial Information
(), Gisle Kleppe
(), Inge Thorsen
() and Jan Ub°e
Abstract: In this paper we propose a modified gravity model that
takes into account that a population generally consists of heterogeneous
groups, and we suggest a new statistical test for heterogeneity. We apply
our new model to two real world data sets, and it turns out that this new
model fits the data surpricingly well. Not only is the effect of
heterogeneity strongly significant, the model also provides far better fits
than traditional trip-distribution models on these particular data sets.
