Freight Transportation System Condition & Performance
Condition of U.S. roadways by functional system
U.S. bridges rated in poor condition
Highway tunnels with limiting characteristics for freight transportation
Class I railroad locomotive fleet by year built
Automated Track Inspection Program (ATIP) exceptions per 100 miles
U.S. flag vessels by type and age
U.S. flag vessels include a wide range of shallow draft and oceangoing vessels that are used to move freight and passengers. Shallow draft vessels (barges and towboats) make up the majority of the fleet and operate domestically on intercoastal waterways and river systems. Inland waterways provide an alternative to truck and rail transportation. A single barge can carry an amount equal to 16 railcars or 70 large semi-truck trailers of dry cargo.
Lock characteristics and delays on rivers with 10,000 or more lockages
Condition of airport runway pavement
Gas distribution pipelines by decade installed
Average truck speeds on select Interstate Highways
The Federal Highway Administration and its private-sector partners measure truck speeds and travel times in urban and rural areas across the United States. This information, available in the National Performance Management Research Data Set, shows average truck speeds tend to drop below the base free-flow speed of 55 miles per hour (mph) on interstates near major urban areas, border crossings and gateways, and in mountainous terrain.

Top 10 metropolitan area congestion rankings
The physical capacity of the U.S. transportation system has not kept pace with growth in travel and commerce. The resulting congestion and delays have significant impacts on passengers and freight shippers. Congestion measures on a national scale are reported in the FHWA Urban Congestion Report based on vehicle probe data. The report tracks congestion measures in the 52 largest metropolitan statistical areas (MSAs). The freeway traffic speeds database used by FHWA provides day-to-day travel time in 5-minute intervals for trucks, passenger vehicles, and all vehicles.

Peak-period congestion on the National Highway System
On weekdays, average speeds during peak periods (between 6:00 a.m. and 9:00 a.m. and between 4:00 p.m. and 7:00 p.m.) are typically lower than those recorded during nonpeak periods. Freight traveling across urban interstate interchanges is affected to the greatest degree by peak-period congestion.
Peak-period congestion on high-volume truck portions of the National Highway System
Congested highways carrying a large number of trucks substantially impede interstate commerce, and trucks on those segments contribute significantly to congestion. On highways carrying more than 8,500 trucks per day, recurring congestion slows traffic on 4,516 miles and creates stop-and-go conditions on another 5,013 miles of the National Highway System.
