Digital billboards called dangerous to drivers

The anti-billboard group Scenic America is touting a new study that concludes that digital billboards are a potentially dangerous distraction to drivers.

A new study published in the journal Traffic Injury Prevention concludes that digital billboards attract and hold the gazes of drivers for far longer than a threshold that previous studies have shown to be dangerous.

The study, conducted by researchers at the Swedish National Road and Transport Research Institute and funded by the Swedish Transport Administration, found that drivers looked at digital billboards significantly longer than they did at other signs on the same stretch of road, with the digital signs often taking a driver’s eyes off the road for more than two seconds.

A well-regarded 2006 study by Virginia Tech for the National Highway Traffic Safety Administration found that anything that takes a driver’s eyes off the road for more than two seconds greatly increases the risk of a crash. The study also found that nearly 80 percent of all crashes involved driver inattention just prior to (within 3 seconds) of the crash.

“This study validates what is common sense when it comes to digital billboards,” said Mary Tracy, president of Scenic America. “Bright, constantly-changing signs on the side of the road are meant to attract and keep the attention of drivers, and this study confirms that is exactly what they do.”

Here's a 2009 Pittsburgh Post-Gazette story on other research that reached a similar conclusion.
