Study: No Matter How You Slice it, Americans Driving Less

Miles driven by U.S. motorists in light-duty vehicles are down about five percent since its peak in 2006, says a University of Michigan researcher.

Following up his recent research that showed that the number of registered vehicles reached a maximum five years ago, Michael Sivak of the U-M Transportation Research Institute found that driving rates, no matter how you measure it (per person, per licensed driver, per household or per registered vehicle), have all declined significantly in recent years. His study also suggests that the cause is not purely economic.

The new study is significant in that it examines recent trends in distances driven by light-duty vehicles (cars, pickup trucks, SUVs, and vans) in the U.S. fleet. This is in contrast to other studies that analyze distances driven by all vehicles (including medium and heavy trucks, buses, and motorcycles).

Sivak found that Americans drove 2.647 trillion miles in 2011 (the latest year available), down from a high of 2.773 trillion miles in 2006. In 1984, the distance driven by light vehicles stood at 1.559 trillion miles. His study also showed that the distance-driven rates per person, per licensed driver and per household all dropped 9 percent since 2004, while the rate per registered vehicle fell 5 percent during that time.

The latest rates (2011) are: distance driven per person, 8,494 miles (down from 9,314 in 2004); distance driven per licensed driver, 12,492 miles (down from 13,711 in 2004); distance driven per household, 22,069 miles (down from 24,349 in 2004); and distance driven per registered vehicle, 11,318 miles (down from 11,946 in 2004).

"All of these rates reached their maxima in 2004, four years prior to the beginning of the current economic downturn," Sivak said. "These reductions likely reflect, in part, noneconomic changes in society that influence the need for vehicles, such as increased telecommuting, increased use of public transportation, increased urbanization of the population and changes in the age composition of drivers.

"Because the onset of the reductions in the driving rates was not the result of short-term economic changes, the 2004 maxima in the distance-driven rates have a reasonable chance of being long-term peaks as well."

In separate research earlier this year, Sivak found that the absolute number of registered vehicles reached a maximum of 236.4 million in 2008, 2.6 million more than in 2011.
