This research provides an example delay calculation for long-haul single unit and combination trucks on Interstate-75 (I-75) in Georgia. Truck profiles on Georgia interstates are used to calculate the value of freight by truck type and commodity moved. Determining the types of trucks and commodities moved within the state of Georgia allows the researcher to monetize the effect of recurring congestion by location in addition to the cost of lost time. A more accurate calculation of delay based on truck type and commodity moved will better inform the Georgia Department of Transportation about the performance of Georgia's major truck routes and its potential effect on the local economy. A review of past research on this topic found that the calculated cost of delay in previous studies varied widely based on truck and commodity type. The identification of the types of commodities moved can assist in better monetizing the value of truck freight. Using forecast data on future truck traffic volume increases in the corridor, the growing importance of putting a value on different types of truck freight delay costs are demonstrated.

Efficient, reliable, and safe freight transportation is critical to the economic prosperity of any region. In the U.S., the dramatic increase in freight volumes has resulted in the growing disparity between demand and capacity. Thus, freight planning is needed to ensure a seamless and effective Texas's transportation system. A clear understanding on the performance of Texas's transportation system, as perceived by the private sector is a critical component in the development of such planning efforts. Against this background, the objective of this research study was to start engaging Texas's shippers and freight stakeholders in a dialogue to provide insight into the adequacy of Texas's transportation system in serving business needs, and any improvements deemed necessary to better serve Texas businesses. The emphases of this study were on the freight concerns and needs, freight policies and strategies, and freight performance measures as expressed by Texas freight stakeholders. / text
