Abstract: This paper describes a Freight Tour Synthesis (FTS) model designed to infer aggregate pick-up/delivery tour flows using secondary data, such as traffic counts and zonal freight trip generation estimates. The formulation combines an entropy maximization demand model together with the secondary data constraints. The entropy function is maximized subject to the system constraints to estimate the most likely freight tours that best fit the secondary data. To assess the role of traffic counts, the authors design four different heuristics to identify the locations of the traffic counts to be used in the estimation, and assess their performance under different scenarios of traffic counts availability.
