Show transcript0:00And finally, on the webcast, we have a dispatch from our digital reporter in South Korea, who discovered that driving down the highway in that country can be a mu- uniquely musical experience,0:09unlike anything you've heard before, and it could even save your life.0:13Intrigued? Here's our Juhee Cho.0:16You see that sign? It says singing highway in Korean. I'm driving about 100 kilometers per hour, and that's about 62 miles per hour in the US.0:27And here we go. Listen to this.0:46Now that was a bit eerie, but just enough to get your attention.0:50The idea came from the Korean Highway Corporation. 68% of highway accidents are caused from falling asleep, speeding, or just not paying attention.1:01We put the melodies in a downhill S-curve road where there's been lots of accidents from dozing and speeding.1:08The road is carved into thousands of grooves. When the car tire hits the groove, the vibration turns into a sound source.1:17It makes different tunes depending on the size of the groove, between 5 to 10 centimeters apart.1:23The rhythm is controlled by the length of the groove. For example, to get one second of the do note, the groove is stretched 28 meters.1:33And the result? Heading to the danger zone, and if you're set just right at the speed limit of 62 miles per hour, you're tuned in for the melody on the singing highway.1:44Ju Hee Cho, ABC News, Sihung, South Korea.
