US driving distances see continued increase

First publishedon www.WorldHighways.com

New data released by the US Department of Transportation’s (USDOT) Federal Highway Administration (FHWA) shows that US driving topped 2.53 trillion kilometres in the first six months of 2017. This continues a streak of steadily increasing vehicle distances travelled that began in 2011.

The new data, published in FHWA’s latest “Traffic Volume Trends” report – a monthly estimate of US road travel – show that more than 448.4 billion km were driven in June 2017 alone, which is 5.4 billion km more than the previous June. The increase in driving over the first half of the year highlights the growing demands challenging the nation’s roads, and reaffirms the importance of improving US transport infrastructure.

The June 2017 report also includes seasonally-adjusted data, which is conducted by USDOT’s Bureau of Transportation Statistics as a way to even out seasonal variation in travel and enable vehicle distance travelled comparisons with any other month in any year. The seasonally-adjusted total vehicle distance travelled for June 2017 were 426.6 billion km. Seasonally adjusted June distance increased by 1% compared to the previous June. The estimates include passenger vehicle, bus and truck travel.

In June, US drivers increased total mileage among all five regions of the United States. At 2.2%, traffic in the West – a 13-state region stretching from California to Montana, and including Hawaii and Alaska – led the nation with largest percentage increase in unadjusted distance travelled.

At 0.5%, the North Central region – a 12-state area stretching from North Dakota to Ohio – had the smallest percentage increase in unadjusted VMT for the month.

At 3.5%, Oklahoma led the nation with the largest unadjusted single-state traffic increase compared to the same month a year earlier, followed by Nevada and Kansas at 3.4% and 3.3% respectively. At 2.3%, Michigan had the nation’s largest unadjusted traffic decrease for the month.

To review the VMT data in FHWA's "Traffic Volume Trends" reports, which are based on information collected from more than 5,000 continuous count stations nationwide.
