Traffic Deaths Soar—Is Cheap Gas a Culprit?
"Traffic fatalities are up 14% so far in 2015, according to new data from the nonprofit National Safety Council," which tracks nationwide fatalities, reports CNN. "That puts the year on pace to be the deadliest for drivers since 2007."
There were more than 18,600 motor-vehicle deaths from January through June this year, compared to 16,400 deaths in the first six months of 2014.
The NSC partly attributes the jump in fatalities to the fact that people are driving more because gas is cheaper. On average, gas prices are down 30% from 2014.
The relationship between cheap gas and increased traffic fatalities was the topic of a "hidden brain" National Public Radio report (listen here) by science correspondent Shankar Vedantam. Increased vehicle miles traveled (VMT) is the chief culprit, be it from cheap gas, improved economy, or both.
I came by this analysis of the relationship between gasoline prices and road fatalities in 144 countries. And what it finds is that higher gas prices are associated with fewer fatalities. Lower gas prices are associated with a larger number of traffic deaths.
"So, Shankar, why is this happening?" asks David Greene, host of NPR's Morning Edition.
"The biggest factor of course is that people simply drive a lot less when gas prices are high," responds Vedantam.
Kim Bellware of the The Huffington Post wrote about the research of "South Dakota State University sociology professor Guangqing Chi, who analyzes the relationship between gas prices and road fatalities" and was also interviewed by Vedantam on NPR.
NPR science correspondent Shankar Vedantam said his "jaw dropped" when he heard the "scary" number. A more conservative calculation based on Chi's research translates into 3,000 more road deaths per year, Vedantam said.
"If the trend continues, traffic deaths this year could exceed 40,000 for the first time since 2007, when there were nearly 44,000 deaths, said Deborah A.P. Hersman, president of the National Safety Council (and former chair of the National Transportation Safety Board ), reports The Oregonian in an article focused on a 32% increase in Oregon traffic deaths from this date last year.
The other factor causing an increase in fatalities is the improved economy. "There are also more commuters on the road heading to work, since the U.S. economy has been steadily adding jobs throughout 2015," notes CNN.
Back to NPR: "Is there something that government officials should be thinking about doing to raise awareness of this problem?" asks Greene.
"Well, David, the obvious answer is that higher gas prices are probably going to save lives," responds Vedantam. "Chi himself thinks that we should maybe impose gasoline taxes, raise the price of gasoline - and that would not make consumers happy - but it probably would save lives."
