Alternative methods for transferring Logit models of gap-acceptance behaviour are implemented and compared in this study using experimental data collected at two priority intersections. The effectiveness of model transfer is evaluated on the basis of several indicators proposed in the literature regarding travel demand applications of transferability, and the results are compared to those obtained by locally estimating the model in the application context. The main conclusion is that the accuracy of the transferred models is generally similar to that of the locally estimated ones, and that the method known as Combined Transfer Estimation performs best among the tested approaches. These results are not significantly affected by the size of the sample of observations used for model transfer.

Abstract
Alternative methods for transferring Logit models of gap-acceptance behaviour are implemented and compared in this study using experimental data collected at two priority intersections. The effectiveness of model transfer is evaluated on the basis of several indicators proposed in the literature regarding travel demand applications of transferability, and the results are compared to those obtained by locally estimating the model in the application context. The main conclusion is that the accuracy of the transferred models is generally similar to that of the locally estimated ones, and that the method known as Combined Transfer Estimation performs best among the tested approaches. These results are not significantly affected by the size of the sample of observations used for model transfer.
