Abstract
This thesis studies the effects of spatial attributes of establishments and other relevant attributes, e.g., employment, fleet size by type, and establishment area on the estimation of nationwide Freight Generation (FG) and Freight Trip Generation (FTG) models. Spatial attributes can help explaining the influence of ports, and major cities on freight activity of establishments across the nation. Although employment has proved to be highly significant in producing unbiased estimates for freight activity, some FG/FTG models that only consider employment have low explanatory power, exhibited by low R2 values. Hence, the need to include other attributes, to increase the explanatory power of the model. Among these attributes, spatial attributes have proved to be highly significant in explaining FG/FTG patterns.
