GOODS©
(General Optimization of Distribution Systems) is a modeling framework
designed to support the analysis of freight traffic flows at the
regional or urban level.
The GOODS©
model uses data on current traffic flows, regional
economic growth potentials, and specific industrial development
proposals to develop total freight traffic flows and forecasts.
The methods used in the GOODS©
model include specific and different analysis systems for bulk,
unitized traffic (container or trailer on flat car or truck), and
parcel traffic. Bulk traffic is forecast on a product-specific basis
(e.g., coal, ores, grains, and oil), while non-bulk traffic is forecast
using more aggregate maket-related techniques. The impact of new
routes, infrastructure, costs, or service implications is assessed
to provide both modal and route choice traffic predictions.
The evaluation processes of the GOODS©
model include both financial and economic analyses
that identify the commercial potential of new transportation infrastructure,
as well as the economic benefits to users and surrounding communities.
The GOODS©
model operates directly in conjunction with
the Economic Rent Model RENTS©
to provide output benefits (employment, income, and property values)
associated with any specific freight infrastructure improvement.
