City Driving Spikes, Rural Driving Falls as Opportunity Shifts
USA Today: The divide between urban and rural America in widening in another area that has nothing to do with politics: driving.U.S. city driving has spiked since 2000, while rural driving has declined in a sudden turnabout that cannot be explained by population trends, according to a University of Michigan Transportation Research Institute study released Tuesday.

Miles driven in urban environments rose by 33% from 2000 to 2016, according to the study. Miles driven in rural areas fell by 12%. Population changes don't explain the trend. During the same period, the number of people living in urban areas rose by 19%, while the rural population was flat.

U.S. Drivers Log 2.4 Trillion Miles In First Nine Months of 2016
USDOT FHA: New data released today by the U.S. Department of Transportation’s (USDOT) Federal Highway Administration (FHWA) show that U.S. driving topped 2.4 trillion miles in the first nine months of 2016, lengthening a series of consecutive monthly increases that started in April 2014.

The new data, published in FHWA’s latest “Traffic Volume Trends” report – a monthly estimate of U.S. road travel – show that more than 265.5 billion miles were driven in September 2016 alone which is a 2.9 percent increase over the previous September. The increase in driving highlights the growing demands facing the nation’s roads and reaffirms the importance of the “Fixing America’s Surface Transportation” (FAST) Act, which is investing $305 billion in America’s surface transportation infrastructure – including $226 billion for roads and bridges – until 2020.

3% Increase in Travel
The 3% increase in fuel utilization in the first six months of 2016 is the best estimate of overall increase in travel miles.  In just one year there would not be that much of a change in miles per gallon or an increase in non-gas type of vehicles, and the distribution by vehicle type (e.g., CMV,  nonCMV) would not change that much either.  So we can conclude that about 3% of the change, and possibly as much as 4 to 6% over the 2014-2016 was the result of this demographic change.

U.S. Drivers Consumed 71.8 Billion Gallons of Gasoline in First Half of 2016

American vehicles consumed 71.8 billion gallons of gasoline in the first half of 2016, an increase of 3 percent over the same period a year earlier. It is the highest amount on record and the sixth consecutive increase in national gasoline consumption for the first six months of any year on record.

Express Lanes Have a Popularity Problem

Highway express lanes provide a faster trip for carpoolers, people who drive low-emission cars, and solo travelers who are willing to pay more. That’s the idea, anyway. But as Americans drive more miles than ever before, express lanes are facing a challenge: they are too popular. So many drivers of all kinds are using the lanes that it is increasingly difficult for transportation officials to keep them speedy.

Methodologies Used to Estimate and Forecast Vehicle Miles Traveled (VMT)
Texas A&M Transportation Institute: Vehicle miles traveled (VMT) is a measure used in transportation planning for a variety of purposes. It measures the amount of travel for all vehicles in a geographic region over a given period of time, typically a one year period. VMT is calculated by adding up all the miles driven by all the cars and trucks on all the roadways in a region. This metric plays an integral role in the transportation planning, policy making, and revenue estimation processes due to its ability to indicate travel demand and behavior.
