ABSTRACT

The gravity models including the entropy maximization model has been applied to almost every trip distribution analyses between regions not only in passenger trips but also in freight movements. In this study, the gravity model and the intervening opportunity model are theoretically compared and empirically examined using TCS(Toll Collecting System) data of Korean Express Highway Company to show the suitability of the models. As a result, the intervening opportunity model is more suitable than the entropy maximization type gravity model in case of heavy truck movements which are usually used for long-distance shipment. This means that long-distance vehicular movements are influenced much more by the opportunities, which reflect the social and economic attractiveness, allowed in destination than by the travel costs to destination. In conclusion, this study suggests that different types of trip distribution models should be applied to estimate the interregional movements of heavy trucks and passenger vehicles.
