Congestion Impact Analysis of Freight Significant Highway Locations – 2015

Nov 182015

Since 2002, the American Transportation Research Institute (ATRI) has collected and processed truck GPS data in support of the Freight Performance Measures (FPM) initiative, a program that maintains and monitors a series of performance measures related to the nation’s truck-based freight transportation system. The measures resulting from this ongoing analysis quantify the impact of traffic congestion on truck-borne freight at 250 specific locations. The information provided through this effort can empower decision-making in both the private and public sectors by allowing stakeholders to better understand the severity of congestion and mobility constraints on the U.S. highway transportation system. This is of particular importance as the nation weighs the needs and resources available for transportation funding. On a state and local level, this research can inform local investment decisions that can directly improve supply chain efficiency. This “bottleneck” analysis incorporates and synthesizes several unique components, including a massive database of truck GPS data at freight-significant locations throughout the United States (U.S.), and an algorithm that quantifies the impact of congestion on truck-based freight. Since its inception, the monitored list has grown to 250 freight-significant locations. In addition, the annual reports provide a chronological repository of mobility profiles, whereby congestion changes can be assessed over time. This, in turn, allows transportation analysts and planners to conduct performance benchmarking and identification of influential factors contributing to congestion and the requisite consequences on truck-freight mobility.
