This paper is intended to account spatial structure effects on freight demand using aggregate data. Spatial structure affects travel decisions, if it is not included in the model, then it could lead to a biased model. Spatial structure effects are usually studied using competing destinations models, which need disaggregate data. This paper presents the adaptation of competing destinations model together with intervening opportunities models to account for spatial structure effects using aggregate data. The application of the model shows that competing effects occur at origin zone, while agglomeration effects occur at destination zones
