|Since 2002, the American Transportation Research Institute (ATRI) has collected and processed truck GPS data in support of the Federal Highway Administration’s 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 metrics that generate from ATRI’S ongoing truck bottleneck analysis quantify the impact of traffic congestion on truck-borne freight at 300 specific locations, a list that has grown since the first iteration of this report. In this most recent 2018 truck bottleneck report, the list of locations monitored has increased from 250 to 300. The increase in monitored locations derives from a 2017 expanded outreach initiative that solicited additional bottleneck locations from public and private sector freight stakeholders. The locations were then assessed using the GPS data processing system.
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 can empower 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 United States (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 truck-freight mobility.
