Figure 3-20. Intensity of Truck Freight Congestion on Selected Interstate Highways: 2011

To better understand the intensity of truck congestion and reliably issues, FHWA combined truck volumes from the Freight Analysis Framework with average truck speeds measured in the Freight Performance Measurement Program. This type of information is useful to private- and public-sector freight stakeholders that wish to better understand the severity of congestion and mobility constraints experienced along the highway transportation system. Many major urban areas have Interstates with significant truck volumes that are experiencing average speeds of less than 55 mph.
