Transferability of Fuzzy Models of Gap-Acceptance Behavior

The transferability of fuzzy models of gap-acceptance behavior between different intersections is evaluated in this paper using a method known as ROC curve analysis. The results of an application to four unsignalized intersections indicate that, even if transferred models generally perform adequately, intersection geometric and traffic characteristics may be very important in determining the capability of a model developed in a given context to reproduce gap-acceptance behavior observed in other contexts.
