This report presents the results of a pilot study to determine the utility of developing a particular travel forecasting technique. The technique in question is a gravity-based model which requires ramp volume data as inputs. The model is used to forecast ramp-to-ramp trip tables. The preliminary study indicates that this technique is sufficiently accurate to warrant further investigation.
