From page 44... ... 40 These considerations suggest that ensuring a good match between land use classes and the underlying FG and FTG patterns could be accomplished by either one of the following: • Redesigning FG and FTG modeling so that it could be properly linked to the land use classification system being used at a particular jurisdiction, and/or • Fostering the use of land use classification systems that are consistent with the underlying patterns of FG and FTG. An attractive way to redesign FG and FTG modeling to deal with the challenge associated with the potentially significant number of different definitions of land use is to: • Estimate FG and FTG models for the various industry sectors captured by the CFS data.

This alternative, however, does require a complementary step, involving a simple model to estimate freight traffic from the estimates of tonnage. Read the entire page →
From page 46... ... 42 • Develop simple computational tools to convert the FG and FTG models by industry sectors into models that match the land use classes used by the transportation agencies in charge of the analyses as well as estimate freight traffic from the FG models developed from the CFS micro-data. Summary The analyses indicate that the ability of land use variables to explain FG and FTG depend on how well the different land use classes are able to represent the economic/logistic processes that impact FG and FTG.
