Abstract:Transshipment has large implications for the provision of public infrastructure, and most of the available data on commodity shipments within a single country do not identity any transshipment points along their way. The Ontario Commercial Vehicle Survey (CVS) is one of the few databases that contain substantial transshipment information. The analysis of the Ontario CVS focused on the commodities of truck trips and trip origin/destination facilities. The Ontario CVS dealt with all commodities that are shipped by truck, with manufactured products leading the list of commodities shipped. Probable transshipment points within the Ontario CVS are terminals and warehouses. Chi-square tests demonstrated that the various commodities have differing trip length distributions and that trip origin/destination facility types also differ with respect to their trip length distributions. The Ontario Commercial Vehicle Survey proved to have useful data on transshipment that can suggest relationships that would be applicable to goods movements in the United States.
