Abstract
The ability to determine the volumes of freight (specifically trucks) passing through a state or metropolitan area is difficult to determine/forecast because transportation professionals have no direct survey mechanism to collect this data. This paper documents various procedures developed to utilize the Freight Analysis Framework Version 2 Database to determine the number of trucks passing through the entire state and an urban area in Alabama. The procedures developed in this research focus on national level pass through data, trips from one state to another that pass through a state only because of that state’s location; pass through from a port of entry to the country where an urbanized area is located on a major corridor; and statewide level through trip data, trips from one part of a state to another that pass through an urbanized area because of its geographic location. The need for, and application of, the pass through freight forecasting is evident in the transportation planning models each metropolitan area and state are expected to develop and maintain for evaluating transportation projects. The ability to accurately forecast the pass through freight movements will benefit transportation planners by identifying freight volumes that must be accommodated by existing and proposed infrastructure, but for which the state or metropolitan area has no direct method to survey.
