New Data Show U.S. Drivers Topped 3 Trillion Miles Last Year

Increased Demand on Nation’s Roads Underscores Need for Transportation Investment

WASHINGTON –New estimates released today by the U.S. Department of Transportation’s Federal Highway Administration (FHWA) show that Americans drove nearly 3.02 trillion miles in 2014, the highest point since 2007 and the second-highest since data collection began 79 years ago, fueling calls for greater investment in transportation infrastructure to accommodate growing volumes of traffic.

The new data reaffirm projections made by U.S. Transportation Secretary Anthony Foxx in “Beyond Traffic,” his 30-year vision for transportation, which shows significant increases in gridlock nationwide unless changes are made in the near-term.

“Americans are driving their cars at near-record levels, and being stuck in traffic is costing drivers an average of nearly five days a year,” said Secretary Foxx. “To ensure this problem doesn’t get worse, greater innovations and investments are needed. We can’t keep treating America’s 21st-century traffic needs with 20th-century solutions.”

According to FHWA’s latest “Traffic Volume Trends” report – a monthly estimate of U.S. road travel – Americans drove an estimated 3.015 trillion miles last year, roughly the same distance as 323 round trips from Earth to Pluto.

Drivers in December 2014 logged 251.4 billion miles, the highest level for any December since data collection began in 1939. At 5 percent higher than the previous December, it was the year’s biggest single-month increase and the nation’s tenth consecutive month of VMT growth.

Traffic in the South Gulf – a block of eight states including Texas and Kentucky – rose to nearly 49.1 billion vehicle miles traveled (VMT), a gain of 6.4 percent over the previous December and the tenth consecutive month of increased traffic for the region.

All states recorded traffic increases in December. At 10.5 percent, Indiana led the nation with the largest single-state traffic increase compared to the same month a year earlier, followed closely by Oklahoma at 9.3 percent and Montana at 8 percent.

“Data like these are critical to helping federal and state transportation leaders understand the challenges facing American drivers,” said Deputy Federal Highway Administrator Gregory Nadeau. “The nation’s growing demand on roads and bridges underscores what we have been saying – increased investment is needed if we are to keep our roads from becoming parking lots.”
