Identifying Freight Intermediaries. Implications for Modeling of Freight Trip Generation

Journal article, 2015

This study discusses freight trip generation of pure receiver establishments, establishments that only receive goods, and freight intermediaries, establishments that both receive and ship goods. In addition, freight trip attraction and freight trip production patterns of establishments in different industry sectors were compared by using freight generation models. The analyses indicated important differences between production and attraction between establishments across and within industry segments and between pure receivers and intermediaries. As a result, econometric models (discrete and discrete-continuous models) were estimated to identify intermediary establishments. External data were used to validate the estimated models. The analyses and models could be used to improve modeling of freight trip generation.
