Abstract
Reliably forecasting freight demand has become essential in freight
transportation management in order to systematically plan for future
transportation facility needs. Land use is one of the key factors that affect
commodity flow. Other factors include location factors, physical factors,
operational factors, dynamic factors such as seasonal variations in demand and
changes in customers’ tastes, and pricing factors. Modeling commodity flows
with land use is one possible first step; however, it has some limitations because
land use data lacks detailed information on economic activities in particular land
use. Hence, models that use land use characteristics instead of aggregate land use
type data were developed in this study using the commodity flow data available
from the 2002 Commodity Flow Survey and other data available to the public via
the Internet. These models were used to estimate commodity flow in 2007 and
their estimates were compared with commodity flow values found in the 2007
Commodity Flow Survey. Results of this comparison showed that the models
could produce good estimates of commodity flows and are of practical use
because the model’s input data are available free via the Internet.
Keywords: commodity flow modeling, land use characteristics, economic
factors.
