A Demand Model for International Freight Transport by Road

This paper presents a system of models for the estimation of road international (import/export) freight flows by using a partial share approach. It allows to simulate generation (for export), attraction (for import) and distribution steps for the estimation of freight flows in quantities (commodity approach), from which the conversion in vehicles is made by using vehicle loading models. This modeling system has been specified according to an easy-to-use philosophy (suitable to be used for forecasting) by using aggregate variables, such as GDP. The calibration is carried out by using a set of available data in Italy that allowed to consider import/export flows by road for 3 different freight types (perishable, industrial, and consumption goods).
