The movement of freight in terms of specific commodities and motor carriers, is illusive at the national and state levels. At the national level, the Bureau of Transportation Statistics (BTS) uses Freight Analysis Framework (FAF) to approximately estimate the movements of commodities on the nation�s transportation networks. While FAF is an arduous and admirable effort with much success at the national level, its derived routing details at state and metropolitan level can deviate appreciably from the actual local truck and freight movements.
To address this, the state and metropolitan level motor carrier tracking and OD study will provide much needed facts on calibrating FAF�s freight routing algorithm, at the national level, and shed light on the amount Tennessee is under-refunded at the state level. Multiple temporary Automated License Plate Recognition (ALPR) stations will be set up at strategic Interstate locations where motor carriers enter or exit Tennessee. The plates will be read, recognized, and matched so that the origin- destination (OD) information of the vehicles can be used to generate an aggregated picture of freight movements specifically into, out of, and through Tennessee. Results of this effort could serve to calibrate FAF�s truck routing statistics for the State of Tennessee. They could also be used to assess the fairness of IFTA fuel tax refund mechanism. |
