Since 2002, the American Transportation Research Institute (ATRI) has collected and processed truck GPS data in support of numerous U.S. DOT freight mobility initiatives. Using truck GPS data from nearly 1 million trucks, ATRI develops and monitors a series of key performance measures on the nation’s freight transportation system. ATRI now converts its truck GPS dataset into an ongoing analysis that is used to quantify the impact of traffic congestion on truck-borne freight at 300 specific locations.

Measuring the performance of freight movement across our nation’s highways is critical to understanding where and at what level investment should be made. The information provided through this effort empowers decision-making in both the private and public sectors by helping stakeholders 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 U.S., and an algorithm that quantifies the impact of congestion on truck-based freight. 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 freight mobility.
